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

Be aware that you'll run into problems if you have a very large number of files in the directory.

If you think this is likely to affect you, consider using a lower level approach such as opendir.

Answer 2

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

Answer 3

/* Delete Cache Files Here */
$dir = "cache/"; /** define the directory **/

/*** cycle through all files in the directory ***/
foreach (glob($dir."*") as $file) {
//foreach (glob($dir.'*.*') as $file){

/*** if file is 24 hours (86400 seconds) old then delete it ***/
if (filemtime($file) < time() - 172800) { // 2 days
    unlink($file);
    }
}

Hope it help you.
