How can PHP developers automate the deletion of XML files that are no longer needed?

To automate the deletion of XML files that are no longer needed, PHP developers can create a script that scans a specific directory for XML files and deletes those that meet certain criteria, such as being older than a certain date or no longer referenced in a database. This script can be run on a scheduled basis using a cron job to ensure that unnecessary XML files are regularly removed. 

<?php
$directory = '/path/to/xml/files/';
$files = glob($directory . '*.xml');

foreach ($files as $file) {
    if (filemtime($file) < strtotime('-7 days')) { // Change the time criteria as needed
        unlink($file);
        echo "Deleted: $file\n";
    }
}
?>
