Auto delete all files after x-time

Question

How do you auto delete all files under a sub directory after x-time (let say after 24 hours) - without using a cronjob command from server or pl. How can you do this just us

Answer 1

function deleteCachedData($hours=24)
{
    $files = glob(ROOTDIR.DIRECTORY_SEPARATOR.'tmp'.DIRECTORY_SEPARATOR.'*.txt');
    foreach($files as $file) {
        if(is_file($file) && (time() - filectime($file)) > $hours*3600) {
            unlink($file);
        }
    }

}
