Retrieving Data for a Specific Key

The get function in SessionForge allows you to retrieve the data stored for a specific key in the session. This can be useful for accessing individual session variables. Below is an example code snippet demonstrating how to use the get function to retrieve data for a specific key.

require 'path/to/SessionForge.php'; // Adjust the path as needed

use SessionForge\SessionForge;

try {
    // Step 1: Set Up Configuration
    $config = [
        'path' => __DIR__ . '/sessions', // Directory to store session files
        'sessionId' => 'your_session_id', // Default session ID
        'hashKey' => 'your_hash_key', // Key for hashing
        'validUntil' => 3600, // Session expiration time in seconds
        'compress' => true, // Enable compression
        'encryption' => true, // Enable encryption
        'key' => 'your_encryption_key' // Encryption key
    ];

    // Step 2: Instantiate SessionForge
    $sessionForgeExample = new SessionForge($config);

    // Step 3: Retrieve data for a specific key
    print_r($sessionForgeExample->get('key6'));
} catch (SessionForgeExceptions $th) {
    print_r($th->formatMessage());
}

Explanation

• Configuration Setup: The configuration array is set up with necessary options such as session file path, session ID, hash key, expiration time, compression, encryption, and encryption key.
• SessionForge Initialization: An instance of the SessionForge class is created using the configuration array.
• Retrieving Data for a Specific Key: The get function is called with the desired key (in this case, 'key6') to retrieve the data stored for that key in the session.

Usage Notes

• The get function returns the data stored for the specified key.
• If the key does not exist in the session, null is returned.

By utilizing the get function, you can easily access and retrieve specific session data stored for a particular key, allowing you to work with individual session variables in your application.
