The correct way to delete all files older than 2 days in PHP

Question

Just curious

        $files = glob(cacheme_directory().\"*\");
        foreach($files as $file)
        {
            $filemtime=filemtime ($file);
                  


        

Answer 1

/** It deletes old files.
 *  @param string $dir Directory
 *  @param int $secs Files older than $secs seconds
 *  @param string $pattern Files matching $pattern
 */
function delete_oldfiles($dir,$secs,$pattern = "/*")
{
    $now = time();
    foreach(glob("$dir$pattern") as $f) {
      if (is_file($f) && ($now - filemtime($f) > $secs)) unlink($f);
    }
}
