How can PHP developers ensure the secure and efficient deletion of files within a specified timeframe?

To ensure the secure and efficient deletion of files within a specified timeframe, PHP developers can use the `unlink()` function to delete the files. Additionally, they can set up a cron job or a scheduled task to run a PHP script that deletes the files after a certain period of time has elapsed. 

<?php
// Specify the file path
$file = 'path/to/file.txt';

// Check if the file exists and delete it
if(file_exists($file)){
    unlink($file);
    echo 'File deleted successfully.';
} else {
    echo 'File does not exist.';
}
?>
