php explode file extension name giving null -

so, when upload files, want check file extension is:

$files      = $_files['files'];

$files_name      =  $files['name'];

shows: `"img.jpg"'

$files_name_explode = end(explode('.', $files_name));

getting null.

what doing wrong?

thanks

use below code :

$path = $_files['files']['name']; $ext = pathinfo($path, pathinfo_extension);

hope :)
