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

Looks correct to me. I'd just suggest you replace 172800 with 2*24*60*60 for clarity.
