function sb_return_kbytes error on PHP 7

In the function sb_return_kbytes, PHP now issues a notice (which my site kindly displays on the public side of the site) indicating that at line 267 (when the case is “m”) the computation is working with non-numeric data. Indeed, the “M” or “G” are still embedded in the $val variable. The following code corrects the issue:

function sb_return_kbytes($val) {
        $val = trim($val);
        $last = strtolower($val[strlen($val)-1]);
        $val = preg_replace("/[^0-9.]/", "", $val);  // <- add this line
        switch($last) {
                case 'g':
                        $val *= 1024;
                case 'm':
                        $val *= 1024;
        }
   return intval($val);
}
