What are the alternative methods to passing data in a URL in PHP?

Passing sensitive data in a URL can pose security risks as the data is visible in the browser's address bar and can be easily intercepted. To address this issue, alternative methods such as using POST requests, sessions, or encryption can be employed to securely pass data in PHP. 

// Using POST requests to pass data securely
<form action="process_data.php" method="post">
    <input type="hidden" name="data" value="sensitive_data">
    <input type="submit" value="Submit">
</form>

// Using sessions to pass data securely
<?php
session_start();
$_SESSION['data'] = 'sensitive_data';
?>

// Using encryption to pass data securely
<?php
$encrypted_data = openssl_encrypt('sensitive_data', 'AES-256-CBC', 'secret_key', 0, 'initialization_vector');
$decrypted_data = openssl_decrypt($encrypted_data, 'AES-256-CBC', 'secret_key', 0, 'initialization_vector');
