In PHP, how do I hash arrays for production systems?

Hashing arrays is an important technique for ensuring data integrity and security in production systems. In PHP, you can use various hashing algorithms to convert an array into a hashed string. Below is an example of how to hash an array using PHP's built-in functions.


        <?php
        // Sample array
        $data = [
            'name' => 'John Doe',
            'email' => 'john@example.com',
            'password' => 'securepassword'
        ];

        // Convert array to JSON string
        $jsonData = json_encode($data);

        // Hash the JSON string
        $hash = hash('sha256', $jsonData);

        // Output the hashed value
        echo 'Hashed value: ' . $hash;
        ?>
