file_1.ext file_2.ext file_3.ext file_10.ext file_40.ext
function mycmp($a, $b) { if ($a == $b) { return 0; } $a_n = preg_match("/\D+(\d+)\D+/", $a, $a_out); $b_n = preg_match("/\D+(\d+)\D+/", $b, $b_out);
return ($a_n[1] < $b_n[1]) ? -1 : 1;
you need to use the $x_out variables:
return ($a_out[1] < $b_out[1]) ? -1 : 1;
if all the names are prefixed with 'file_' it might be a bit more efficiant if you do something other than preg_match():
$a_n = (int) substr($a, 5); // (int) forces 10.ext -> 10 $b_n = (int) substr($b, 5);
return ($a_n < $b_n) ? -1 : 1;

I don't know what the names are. I just know that there might be numbers. :)
It still doesn't work. It gives very odd results with the $x_out variables.
