We get user preferences from the URL query string and use them to filter the products.\n3. We use a `SELECT` query to retrieve the filtered products from the database.\n4. We display the filtered products in a table.\n5. We close the database connection.\n\n**Example Use Case**\n\n1. Open `index.html` in a web browser.\n2. Select a brand and category from the dropdown menus.\n3. Enter a price range in the input fields.\n4. Click the \"Filter\" button.\n5. The filtered products will be displayed in a table.\n\nNote: This is a basic example and you may want to add additional functionality such as pagination, sorting, and error handling.","**Creating a Dynamic Product Filtering Website with PHP and Database**\n\nTo create a dynamic website that displays information about a specific set of products and allows users to filter them by various attributes, you can use PHP to interact with a database. In this example, we'll use MySQL as the database management system and PHP to create a simple product filtering system.\n\n**Database Design**\n\nFirst, let's design a basic database schema to store product information and user preferences:\n\n```sql\nCREATE TABLE products (\n id INT PRIMARY KEY AUTO_INCREMENT,\n name VARCHAR(255) NOT NULL,\n brand VARCHAR(255) NOT NULL,\n category VARCHAR(255) NOT NULL,\n price DECIMAL(10, 2) NOT NULL\n);\n\nCREATE TABLE user_preferences (\n id INT PRIMARY KEY AUTO_INCREMENT,\n user_id INT,\n product_id INT,\n category VARCHAR(255),\n price_range VARCHAR(255)\n);\n```\n\n**PHP Code**\n\nNext, let's create a PHP script to connect to the database, retrieve products, and filter them based on user preferences:\n\n**config.php**\n```php\nconnect_error) {\n die(\"Connection failed: \" . $conn->connect_error);\n}\n?>\n```\n\n**filter.php**\n```php\nquery($query);\n\n// Define filters\n$categories = array();\n$price_ranges = array();\n\n// Retrieve user preferences\n$query = \"SELECT category, price_range FROM user_preferences\";\n$result = $conn->query($query);\nwhile ($row = $result->fetch_assoc()) {\n $categories[] = $row['category'];\n $price_ranges[] = $row['price_range'];\n}\n\n// Filter products\n$filtered_products = array();\nforeach ($result as $product) {\n if (in_array($product['category'], $categories) && in_array($product['price'], $price_ranges)) {\n $filtered_products[] = $product;\n }\n}\n\n// Display filtered products\nforeach ($filtered_products as $product) {\n echo \"Product Name: \" . $product['name'] . \"
\";\n echo \"Brand: \" . $product['brand'] . \"
\";\n echo \"Category: \" . $product['category'] . \"
\";\n echo \"Price: $\" . $product['price'] . \"

\";\n}\n?>\n```\n\n**filter_form.php**\n```php\nquery($query);\nwhile ($row = $result->fetch_assoc()) {\n $categories[] = $row['category'];\n $price_ranges[] = $row['price_range'];\n}\n\n// Display filter form\necho \"Select category: \";\necho \"\";\nforeach ($categories as $category) {\n echo \"$category\";\n}\necho \"\";\n\necho \"
Select price range: \";\necho \"\";\nforeach ($price_ranges as $price_range) {\n echo \"$price_range\";\n}\necho \"\";\n\n// Process filter form\nif (isset($_POST['filter'])) {\n $category = $_POST['category'];\n $price_range = $_POST['price_range'];\n\n // Filter products\n $query = \"SELECT * FROM products WHERE category = '$category' AND price BETWEEN \" . $price_range[0] . \" AND \" . $price_range[1];\n $result = $conn->query($query);\n while ($product = $result->fetch_assoc()) {\n echo \"Product Name: \" . $product['name'] . \"
\";\n echo \"Brand: \" . $product['brand'] . \"
\";\n echo \"Category: \" . $product['category'] . \"
\";\n echo \"Price: $\" . $product['price'] . \"

\";\n }\n}\n?>\n```\n\n**Example Use Case**\n\n1. Run `filter.php` to display all products.\n2. Run `filter_form.php` to display the filter form.\n3. Select a category and price range from the form.\n4. Click the \"Filter\" button to display the filtered products.\n\nNote: This is a basic example and does not include any validation or error handling. You should consider adding these features to make your website more secure and user-friendly.

\\n Reset Filter\\n \\n\\n\\n```\\n\\n**Explanation**\\n\\n1. We create a database connection using MySQLi in PHP.\\n2. We get user preferences from the URL query string and use them to filter the products.\\n3. We use a `SELECT` query to retrieve the filtered products from the database.\\n4. We display the filtered products in a table.\\n5. We close the database connection.\\n\\n**Example Use Case**\\n\\n1. Open `index.html` in a web browser.\\n2. Select a brand and category from the dropdown menus.\\n3. Enter a price range in the input fields.\\n4. Click the \\\"Filter\\\" button.\\n5. The filtered products will be displayed in a table.\\n\\nNote: This is a basic example and you may want to add additional functionality such as pagination, sorting, and error handling.\",\n \"**Creating a Dynamic Product Filtering Website with PHP and Database**\\n\\nTo create a dynamic website that displays information about a specific set of products and allows users to filter them by various attributes, you can use PHP to interact with a database. In this example, we'll use MySQL as the database management system and PHP to create a simple product filtering system.\\n\\n**Database Design**\\n\\nFirst, let's design a basic database schema to store product information and user preferences:\\n\\n```sql\\nCREATE TABLE products (\\n id INT PRIMARY KEY AUTO_INCREMENT,\\n name VARCHAR(255) NOT NULL,\\n brand VARCHAR(255) NOT NULL,\\n category VARCHAR(255) NOT NULL,\\n price DECIMAL(10, 2) NOT NULL\\n);\\n\\nCREATE TABLE user_preferences (\\n id INT PRIMARY KEY AUTO_INCREMENT,\\n user_id INT,\\n product_id INT,\\n category VARCHAR(255),\\n price_range VARCHAR(255)\\n);\\n```\\n\\n**PHP Code**\\n\\nNext, let's create a PHP script to connect to the database, retrieve products, and filter them based on user preferences:\\n\\n**config.php**\\n```php\\nconnect_error) {\\n die(\\\"Connection failed: \\\" . $conn->connect_error);\\n}\\n?>\\n```\\n\\n**filter.php**\\n```php\\nquery($query);\\n\\n// Define filters\\n$categories = array();\\n$price_ranges = array();\\n\\n// Retrieve user preferences\\n$query = \\\"SELECT category, price_range FROM user_preferences\\\";\\n$result = $conn->query($query);\\nwhile ($row = $result->fetch_assoc()) {\\n $categories[] = $row['category'];\\n $price_ranges[] = $row['price_range'];\\n}\\n\\n// Filter products\\n$filtered_products = array();\\nforeach ($result as $product) {\\n if (in_array($product['category'], $categories) && in_array($product['price'], $price_ranges)) {\\n $filtered_products[] = $product;\\n }\\n}\\n\\n// Display filtered products\\nforeach ($filtered_products as $product) {\\n echo \\\"Product Name: \\\" . $product['name'] . \\\"

\\\";\\n echo \\\"Price: $\\\" . $product['price'] . \\\"

\\\";\\n }\\n}\\n?>\\n```\\n\\n**Example Use Case**\\n\\n1. Run `filter.php` to display all products.\\n2. Run `filter_form.php` to display the filter form.\\n3. Select a category and price range from the form.\\n4.

The FSM is a mathematical model that can be in one of a finite number of states and can change from one state to another when events occur.\n\n### Installation\n\nTo use this library, you need to install it using Composer:\n```bash\ncomposer require fsmlib/fsm\n```\n\n### API Documentation\n\n#### FSM Class\n\nThe `FSM` class is the core of the library. It takes three arguments: `states`, `events`, and `transitions`. `states` is an array of state names, `events` is an array of event names, and `transitions` is an array of transition rules.\n\n```php\nclass FSM\n{\n private $states;\n private $events;\n private $transitions;\n\n public function __construct(array $states, array $events, array $transitions)\n {\n $this->states = $states;\n $this->events = $events;\n $this->transitions = $transitions;\n }\n\n public function transition(string $currentState, string $event, array $args = []): string\n {\n $transitionRule = $this->getTransitionRule($currentState, $event);\n if ($transitionRule === null) {\n throw new Exception(\"No transition rule found for state '$currentState' and event '$event'\");\n }\n return $transitionRule['nextState'];\n }\n\n private function getTransitionRule(string $currentState, string $event): ?array\n {\n foreach ($this->transitions as $transition) {\n if ($transition['fromState'] === $currentState && $transition['event'] === $event) {\n return $transition;\n }\n }\n return null;\n }\n}\n```\n\n#### Mod-Three Procedure Example\n\nThe `mod-three` procedure is a simple example of a FSM. It has three states: `start`, `success`, and `failure`. When an event `input` occurs, the FSM transitions from `start` to `success` if the input is divisible by 3. Otherwise, it transitions from `start` to `failure`. If the FSM is already in `success` or `failure`, the event `input` has no effect.\n\n```php\n$states = ['start', 'success', 'failure'];\n$events = ['input'];\n$transitions = [\n ['fromState' => 'start', 'event' => 'input', 'condition' => function ($input) { return $input % 3 === 0; }, 'nextState' => 'success'],\n ['fromState' => 'start', 'event' => 'input', 'nextState' => 'failure'],\n];\n\n$fsm = new FSM($states, $events, $transitions);\n\n// Test the FSM\nprint($fsm->transition('start', 'input', [5]) . \"\\n\"); // Output: failure\nprint($fsm->transition('start', 'input', [6]) . \"\\n\"); // Output: success\nprint($fsm->transition('success', 'input', [5]) . \"\\n\"); // Output: success\n```\n\n### Unit Tests\n\n```php\nclass FSMTest extends TestCase\n{\n public function testTransitionRuleFound()\n {\n $states = ['start', 'success', 'failure'];\n $events = ['input'];\n $transitions = [\n ['fromState' => 'start', 'event' => 'input', 'nextState' => 'success'],\n ];\n $fsm = new FSM($states, $events, $transitions);\n $this->assertEquals('success', $fsm->transition('start', 'input'));\n }\n\n public function testTransitionRuleNotFound()\n {\n $states = ['start', 'success', 'failure'];\n $events = ['input'];\n $transitions = [\n ['fromState' => 'start', 'event' => 'input', 'nextState' => 'success'],\n ];\n $fsm = new FSM($states, $events, $transitions);\n $this->expectException(Exception::class);\n $fsm->transition('start', 'non-existent-event');\n }\n\n public function testTransitionRuleWithCondition()\n {\n $states = ['start', 'success', 'failure'];\n $events = ['input'];\n $transitions = [\n ['fromState' => 'start', 'event' => 'input', 'condition' => function ($input) { return $input % 3 === 0; }, 'nextState' => 'success'],\n ];\n $fsm = new FSM($states, $events, $transitions);\n $this->assertEquals('success', $fsm->transition('start', 'input', [6]));\n $this->assertEquals('start', $fsm->transition('start', 'input', [5]));\n }\n}\n```\n\n### README\n\nFSM Library\n------------\n\nThis library provides a simple implementation of a Finite State Machine (FSM) in PHP. It can be used to model systems that can be in one of a finite number of states and can change from one state to another when events occur.\n\nFeatures\n--------\n\n* Simple API for creating FSM instances\n* Supports multiple transitions with conditions\n* Throws an exception when no transition rule is found for a given state and event\n\nInstallation\n------------\n\nTo use this library, run the following command in your terminal:\n```bash\ncomposer require fsmlib/fsm\n```\n\nUsage\n-----\n\nCreate a new FSM instance by passing the states, events, and transitions to the constructor:\n```php\n$states = ['start', 'success', 'failure'];\n$events = ['input'];\n$transitions = [\n ['fromState' => 'start', 'event' => 'input', 'nextState' => 'success'],\n];\n$fsm = new FSM($states, $events, $transitions);\n```\nUse the `transition` method to transition to a new state:\n```php\nprint($fsm->transition('start', 'input') . \"\\n\"); // Output: success\n```\nNote that if no transition rule is found for a given state and event, an exception will be thrown.\n\nExample Use Cases\n----------------\n\nThe `mod-three` procedure is a simple example of a FSM. It has three states: `start`, `success`, and `failure`. When an event `input` occurs, the FSM transitions from `start` to `success` if the input is divisible by 3. Otherwise, it transitions from `start` to `failure`.

You can then set the initial state using the `setInitialState` method and add final states using the `addFinalState` method.\n\nTransitions between states can be defined using the `addTransition` method on individual states. The `transition` method can then be used to determine the next state given a current state and input symbol.\n\n### API Documentation\n\n* `State` class:\n * `__construct($name)`: Creates a new state with the given name.\n * `addTransition($inputSymbol, $nextState)`: Adds a transition from this state to the next state given an input symbol.\n* `FiniteStateMachine` class:\n * `__construct()`: Creates a new finite state machine.\n * `addState($name)`: Adds a new state to the FSM.\n * `setInitialState($name)`: Sets the initial state of the FSM.\n * `addFinalState($name)`: Adds a final state to the FSM.\n * `transition($currentState, $inputSymbol)`: Returns the next state given a current state and input symbol.\n* `ModThreeFSM` class:\n * `__construct()`: Creates a new instance of the Mod-3 FSM.\n\n### Example Usage\n\n```php\n$fsm = new ModThreeFSM();\necho \"Initial state: \" . $fsm->initialState->name . \"\\n\";\necho \"Final states: \";\nprint_r($fsm->finalStates);\necho \"\\n\";\n\n$currentState = $fsm->initialState;\n$inputSymbol = '0';\nfor ($i = 0; $i < 10; $i++) {\n $nextState = $fsm->transition($currentState, $inputSymbol);\n echo \"Current state: \" . $currentState->name . \", Next state: \" . $nextState->name . \"\\n\";\n $currentState = $nextState;\n $inputSymbol = ($i % 2) === 0 ?

Here's an example:\n```php\nuse FiniteStateMachine\\FSM;\n\nclass ModThreeFSM extends FSM\n{\n private const INITIAL_STATE = 'zero';\n private const STATES = [\n 'zero' => [],\n 'one' => ['next' => 'two'],\n 'two' => ['next' => 'three'],\n 'three' => ['next' => 'zero'],\n ];\n}\n```\nIn this example, we've defined an FSM called `ModThreeFSM` with four states: `zero`, `one`, `two`, and `three`. The `INITIAL_STATE` property specifies the initial state of the FSM.\n\n### Transitioning between states\n\nTo transition between states, you can use the `transition` method:\n```php\n$fsm = new ModThreeFSM();\n$fsm->transition('zero'); // Transition to state 'one'\n$fsm->transition('one'); // Transition to state 'two'\n$fsm->transition('two'); // Transition to state 'three'\n$fsm->transition('three'); // Transition to state 'zero'\n```\n### Checking the current state\n\nTo check the current state of the FSM, you can use the `getState` method:\n```php\n$fsm = new ModThreeFSM();\n$fsm->getState(); // Returns 'zero'\n$fsm->transition('zero'); // Transition to state 'one'\n$fsm->getState(); // Returns 'one'\n```\n### Implementation\n\nHere's the implementation of the FSM library:\n```php\nnamespace FiniteStateMachine;\n\nclass FSM\n{\n private $states;\n private $currentState;\n\n public function __construct(array $states, string $initialState)\n {\n $this->states = $states;\n $this->currentState = $initialState;\n }\n\n public function transition(string $state): void\n {\n if (!isset($this->states[$this->currentState] ?? null) || !isset($this->states[$this->currentState]['next']) || !isset($this->states[$this->states[$this->currentState]['next'] ?? null])) {\n throw new \\InvalidArgumentException('Invalid state or transition');\n }\n\n $this->currentState = $this->states[$this->currentState]['next'];\n }\n\n public function getState(): string\n {\n return $this->currentState;\n }\n}\n```\n## Unit Tests\n\nHere's an example of how you can write unit tests for the FSM library using PHPUnit:\n```php\nnamespace FiniteStateMachine\\Tests;\n\nuse PHPUnit\\Framework\\TestCase;\nuse FiniteStateMachine\\FSM;\n\nclass FSMTest extends TestCase\n{\n public function testTransition()\n {\n $states = [\n 'zero' => [],\n 'one' => ['next' => 'two'],\n 'two' => ['next' => 'three'],\n 'three' => ['next' => 'zero'],\n ];\n\n $fsm = new FSM($states, 'zero');\n $fsm->transition('zero');\n $this->assertEquals('one', $fsm->getState());\n\n $fsm->transition('one');\n $this->assertEquals('two', $fsm->getState());\n\n $fsm->transition('two');\n $this->assertEquals('three', $fsm->getState());\n\n $fsm->transition('three');\n $this->assertEquals('zero', $fsm->getState());\n }\n\n public function testInvalidState()\n {\n $states = [\n 'zero' => [],\n 'one' => ['next' => 'two'],\n 'two' => ['next' => 'three'],\n 'three' => ['next' => 'zero'],\n ];\n\n $fsm = new FSM($states, 'zero');\n $this->expectException(\\InvalidArgumentException::class);\n $fsm->transition('four');\n }\n}\n```\n## README\n\n### Installation\n\nTo install the library, run the following command:\n```bash\ncomposer require finite-state-machine\n```\n### Usage\n\nTo use the library, create a class that extends the `FSM` class and defines the states and transitions.

The `transition` method can then be used to determine the next state given a current state and input symbol.\\n\\n### API Documentation\\n\\n* `State` class:\\n * `__construct($name)`: Creates a new state with the given name.\\n * `addTransition($inputSymbol, $nextState)`: Adds a transition from this state to the next state given an input symbol.\\n* `FiniteStateMachine` class:\\n * `__construct()`: Creates a new finite state machine.\\n * `addState($name)`: Adds a new state to the FSM.\\n * `setInitialState($name)`: Sets the initial state of the FSM.\\n * `addFinalState($name)`: Adds a final state to the FSM.\\n * `transition($currentState, $inputSymbol)`: Returns the next state given a current state and input symbol.\\n* `ModThreeFSM` class:\\n * `__construct()`: Creates a new instance of the Mod-3 FSM.\\n\\n### Example Usage\\n\\n```php\\n$fsm = new ModThreeFSM();\\necho \\\"Initial state: \\\" . $fsm->initialState->name . \\\"\\\\n\\\";\\necho \\\"Final states: \\\";\\nprint_r($fsm->finalStates);\\necho \\\"\\\\n\\\";\\n\\n$currentState = $fsm->initialState;\\n$inputSymbol = '0';\\nfor ($i = 0; $i < 10; $i++) {\\n $nextState = $fsm->transition($currentState, $inputSymbol);\\n echo \\\"Current state: \\\" . $currentState->name . \\\", Next state: \\\" . $nextState->name . \\\"\\\\n\\\";\\n $currentState = $nextState;\\n $inputSymbol = ($i % 2) === 0 ?

The library is designed to be extensible and allows for easy creation of custom FSMs using the provided API.\\n\\n## Installation\\n\\nTo install the library, run the following command:\\n```bash\\ncomposer require finite-state-machine\\n```\\n## Usage\\n\\n### Creating an FSM\\n\\nTo create an FSM, you need to define the states and transitions. Here's an example:\\n```php\\nuse FiniteStateMachine\\\\FSM;\\n\\nclass ModThreeFSM extends FSM\\n{\\n private const INITIAL_STATE = 'zero';\\n private const STATES = [\\n 'zero' => [],\\n 'one' => ['next' => 'two'],\\n 'two' => ['next' => 'three'],\\n 'three' => ['next' => 'zero'],\\n ];\\n}\\n```\\nIn this example, we've defined an FSM called `ModThreeFSM` with four states: `zero`, `one`, `two`, and `three`. The `INITIAL_STATE` property specifies the initial state of the FSM.\\n\\n### Transitioning between states\\n\\nTo transition between states, you can use the `transition` method:\\n```php\\n$fsm = new ModThreeFSM();\\n$fsm->transition('zero'); // Transition to state 'one'\\n$fsm->transition('one'); // Transition to state 'two'\\n$fsm->transition('two'); // Transition to state 'three'\\n$fsm->transition('three'); // Transition to state 'zero'\\n```\\n### Checking the current state\\n\\nTo check the current state of the FSM, you can use the `getState` method:\\n```php\\n$fsm = new ModThreeFSM();\\n$fsm->getState(); // Returns 'zero'\\n$fsm->transition('zero'); // Transition to state 'one'\\n$fsm->getState(); // Returns 'one'\\n```\\n### Implementation\\n\\nHere's the implementation of the FSM library:\\n```php\\nnamespace FiniteStateMachine;\\n\\nclass FSM\\n{\\n private $states;\\n private $currentState;\\n\\n public function __construct(array $states, string $initialState)\\n {\\n $this->states = $states;\\n $this->currentState = $initialState;\\n }\\n\\n public function transition(string $state): void\\n {\\n if (!isset($this->states[$this->currentState] ?? null) || !isset($this->states[$this->currentState]['next']) || !isset($this->states[$this->states[$this->currentState]['next'] ?? null])) {\\n throw new \\\\InvalidArgumentException('Invalid state or transition');\\n }\\n\\n $this->currentState = $this->states[$this->currentState]['next'];\\n }\\n\\n public function getState(): string\\n {\\n return $this->currentState;\\n }\\n}\\n```\\n## Unit Tests\\n\\nHere's an example of how you can write unit tests for the FSM library using PHPUnit:\\n```php\\nnamespace FiniteStateMachine\\\\Tests;\\n\\nuse PHPUnit\\\\Framework\\\\TestCase;\\nuse FiniteStateMachine\\\\FSM;\\n\\nclass FSMTest extends TestCase\\n{\\n public function testTransition()\\n {\\n $states = [\\n 'zero' => [],\\n 'one' => ['next' => 'two'],\\n 'two' => ['next' => 'three'],\\n 'three' => ['next' => 'zero'],\\n ];\\n\\n $fsm = new FSM($states, 'zero');\\n $fsm->transition('zero');\\n $this->assertEquals('one', $fsm->getState());\\n\\n $fsm->transition('one');\\n $this->assertEquals('two', $fsm->getState());\\n\\n $fsm->transition('two');\\n $this->assertEquals('three', $fsm->getState());\\n\\n $fsm->transition('three');\\n $this->assertEquals('zero', $fsm->getState());\\n }\\n\\n public function testInvalidState()\\n {\\n $states = [\\n 'zero' => [],\\n 'one' => ['next' => 'two'],\\n 'two' => ['next' => 'three'],\\n 'three' => ['next' => 'zero'],\\n ];\\n\\n $fsm = new FSM($states, 'zero');\\n $this->expectException(\\\\InvalidArgumentException::class);\\n $fsm->transition('four');\\n }\\n}\\n```\\n## README\\n\\n### Installation\\n\\nTo install the library, run the following command:\\n```bash\\ncomposer require finite-state-machine\\n```\\n### Usage\\n\\nTo use the library, create a class that extends the `FSM` class and defines the states and transitions.

The `INITIAL_STATE` property specifies the initial state of the FSM.\\n\\n### Transitioning between states\\n\\nTo transition between states, you can use the `transition` method:\\n```php\\n$fsm = new ModThreeFSM();\\n$fsm->transition('zero'); // Transition to state 'one'\\n$fsm->transition('one'); // Transition to state 'two'\\n$fsm->transition('two'); // Transition to state 'three'\\n$fsm->transition('three'); // Transition to state 'zero'\\n```\\n### Checking the current state\\n\\nTo check the current state of the FSM, you can use the `getState` method:\\n```php\\n$fsm = new ModThreeFSM();\\n$fsm->getState(); // Returns 'zero'\\n$fsm->transition('zero'); // Transition to state 'one'\\n$fsm->getState(); // Returns 'one'\\n```\\n### Implementation\\n\\nHere's the implementation of the FSM library:\\n```php\\nnamespace FiniteStateMachine;\\n\\nclass FSM\\n{\\n private $states;\\n private $currentState;\\n\\n public function __construct(array $states, string $initialState)\\n {\\n $this->states = $states;\\n $this->currentState = $initialState;\\n }\\n\\n public function transition(string $state): void\\n {\\n if (!isset($this->states[$this->currentState] ?? null) || !isset($this->states[$this->currentState]['next']) || !isset($this->states[$this->states[$this->currentState]['next'] ?? null])) {\\n throw new \\\\InvalidArgumentException('Invalid state or transition');\\n }\\n\\n $this->currentState = $this->states[$this->currentState]['next'];\\n }\\n\\n public function getState(): string\\n {\\n return $this->currentState;\\n }\\n}\\n```\\n## Unit Tests\\n\\nHere's an example of how you can write unit tests for the FSM library using PHPUnit:\\n```php\\nnamespace FiniteStateMachine\\\\Tests;\\n\\nuse PHPUnit\\\\Framework\\\\TestCase;\\nuse FiniteStateMachine\\\\FSM;\\n\\nclass FSMTest extends TestCase\\n{\\n public function testTransition()\\n {\\n $states = [\\n 'zero' => [],\\n 'one' => ['next' => 'two'],\\n 'two' => ['next' => 'three'],\\n 'three' => ['next' => 'zero'],\\n ];\\n\\n $fsm = new FSM($states, 'zero');\\n $fsm->transition('zero');\\n $this->assertEquals('one', $fsm->getState());\\n\\n $fsm->transition('one');\\n $this->assertEquals('two', $fsm->getState());\\n\\n $fsm->transition('two');\\n $this->assertEquals('three', $fsm->getState());\\n\\n $fsm->transition('three');\\n $this->assertEquals('zero', $fsm->getState());\\n }\\n\\n public function testInvalidState()\\n {\\n $states = [\\n 'zero' => [],\\n 'one' => ['next' => 'two'],\\n 'two' => ['next' => 'three'],\\n 'three' => ['next' => 'zero'],\\n ];\\n\\n $fsm = new FSM($states, 'zero');\\n $this->expectException(\\\\InvalidArgumentException::class);\\n $fsm->transition('four');\\n }\\n}\\n```\\n## README\\n\\n### Installation\\n\\nTo install the library, run the following command:\\n```bash\\ncomposer require finite-state-machine\\n```\\n### Usage\\n\\nTo use the library, create a class that extends the `FSM` class and defines the states and transitions. For example:\\n```php\\nuse FiniteStateMachine\\\\FSM;\\n\\nclass ModThreeFSM extends FSM\\n{\\n private const INITIAL_STATE = 'zero';\\n private const STATES = [\\n 'zero' => [],\\n 'one' => ['next' => 'two'],\\n 'two' => ['next' => 'three'],\\n 'three' => ['next' => 'zero'],\\n ];\\n}\\n```\\nTo transition between states, use the `transition` method:\\n```php\\n$fsm = new ModThreeFSM();\\n$fsm->transition('zero'); // Transition to state 'one'\\n$fsm->transition('one'); // Transition to state 'two'\\n$fsm->transition('two'); // Transition to state 'three'\\n$fsm->transition('three'); // Transition to state 'zero'\\n```\\nTo check the current state, use the `getState` method:\\n```php\\n$fsm = new ModThreeFSM();\\n$fsm->getState(); // Returns 'zero'\\n$fsm->transition('zero'); // Transition to state 'one'\\n$fsm->getState(); // Returns 'one'\\n```\\n### API\\n\\n* `__construct(array $states, string $initialState)`: Creates a new FSM instance with the given states and initial state.\\n* `transition(string $state)`: Transitions to the next state.\\n* `getState(): string`: Returns the current state.\\n\\n### Exceptions\\n\\n* `InvalidArgumentException`: Thrown when an invalid state or transition is attempted.\",\n \"role\": \"assistant\"\n }\n]"}}},{"rowIdx":6,"cells":{"prompt_id":{"kind":"string","value":"7e727ffde5efac49412bde49b55460694c627ff5ab405c8e8190fddac9b744fd"},"prompt":{"kind":"truncated","value":"\"When using react native and firebase, what’s best practice for storing the authenticated session "},"all_generated_responses":{"kind":"truncated","value":"[\"**Storing Authenticated Session and User Data in React Native with Firebase**\\n\\nWhen building a R"},"scores":{"kind":"list like","value":[3.5,2,1.5,0,3],"string":"[\n 3.5,\n 2,\n 1.5,\n 0,\n 3\n]"},"chosen":{"kind":"truncated","value":"[{\"content\":\"When using react native and firebase, what’s best practice for storing the authentica"},"rejected":{"kind":"truncated","value":"[{\"content\":\"When using react native and firebase, what’s best practice for storing the authentica"}}},{"rowIdx":7,"cells":{"prompt_id":{"kind":"string","value":"632115fbbc123bf9b51cc1eb2389bc691578849fef2b2ae41bbfe6cc1fade5a3"},"prompt":{"kind":"truncated","value":"\"help me build a website for an interior designer called Merav Ben Ari.\\nthe website should have a m"},"all_generated_responses":{"kind":"truncated","value":"[\"I can guide you through the process of building a basic website for Merav Ben Ari using HTML, CSS,"},"scores":{"kind":"list like","value":[1.5,2.5,2.5,3,0.5],"string":"[\n 1.5,\n 2.5,\n 2.5,\n 3,\n 0.5\n]"},"chosen":{"kind":"truncated","value":"[{\"content\":\"help me build a website for an interior designer called Merav Ben Ari.\\nthe website sho"},"rejected":{"kind":"truncated","value":"[{\"content\":\"help me build a website for an interior designer called Merav Ben Ari.\\nthe website sho"}}},{"rowIdx":8,"cells":{"prompt_id":{"kind":"string","value":"b4b7eb5cc03aa3559264f1aadf8b4ade71af9f84ec360515bce4480d4b67d1be"},"prompt":{"kind":"truncated","value":"\"Reasoning: Work done by A in 2 days = 2/5\\nRemaining work = 3/5\\nWork done by both A and B in one d"},"all_generated_responses":{"kind":"truncated","value":"[\"I'll solve each question step by step.\\n\\n**Question 1:**\\nA and B can do a work in 5 days and 10 "},"scores":{"kind":"list like","value":[2,1.5,2.5,2,2],"string":"[\n 2,\n 1.5,\n 2.5,\n 2,\n 2\n]"},"chosen":{"kind":"truncated","value":"[{\"content\":\"Reasoning: Work done by A in 2 days = 2/5\\nRemaining work = 3/5\\nWork done by both A an"},"rejected":{"kind":"truncated","value":"[{\"content\":\"Reasoning: Work done by A in 2 days = 2/5\\nRemaining work = 3/5\\nWork done by both A an"}}},{"rowIdx":9,"cells":{"prompt_id":{"kind":"string","value":"34e1ebc15ad170fabccbc38cf31ab41b8b5f270f9dec6219cb3c3cefc6257bd8"},"prompt":{"kind":"truncated","value":"\"Teacher: You are given a sentence in Arabic.
