Use this function to get the oldest file in a directory. Of course there are not so much cases where you can use this, but maybe it's interesting for a study. I used this function together with a delete function on my website to limit the number of files in a directory for an upload demo.

<?php
function get_oldest_file($directory) {
    if (
$handle = opendir($directory)) {
        while (
false !== ($file = readdir($handle))) {
           
$files[] = $file;
        }
        foreach (
$files as $val) {
            if (
is_file($directory.$val)) {
               
$file_date[$val] = filemtime($directory.$val);
            }
        }
    }
   
closedir($handle);
   
asort($file_date, SORT_NUMERIC);
   
reset($file_date);
   
$oldest = key($file_date);
    return
$oldest;
}
// example:
echo get_oldest_file("the_way/to_the/directory");
?>
