How can PHP code be modified to delete cache files in a specific directory at regular intervals?

To delete cache files in a specific directory at regular intervals, you can create a PHP script that runs on a scheduled basis using a cron job. Within the PHP script, you can use functions like `glob()` to get a list of cache files in the directory, and then use `unlink()` to delete each file.

<?php
// Specify the directory where cache files are stored
$directory = '/path/to/cache/directory/';

// Get a list of cache files in the directory
$files = glob($directory . '*');

// Loop through each file and delete it
foreach ($files as $file) {
    if (is_file($file)) {
        unlink($file);
    }
}
?>
