What are some potential pitfalls of using PHP scripts as data containers?

One potential pitfall of using PHP scripts as data containers is the risk of exposing sensitive information if the script is accessed directly by a user. To prevent this, it is important to ensure that the PHP script cannot be accessed directly by setting appropriate file permissions and using input validation to prevent unauthorized access. 

<?php
// Prevent direct access to the data container script
if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
    header('HTTP/1.0 403 Forbidden');
    exit('Access Forbidden');
}

// Validate input before processing data
if (isset($_POST['data'])) {
    $data = $_POST['data'];
    // Process data here
} else {
    header('HTTP/1.0 400 Bad Request');
    exit('Bad Request');
}
