I'm trying sort an array. It has entries like this:
file_1.ext file_2.ext file_3.ext file_10.ext file_40.ext
and so on.
I want to sort them alphabetically first and then by the numbers. If I sort them normally I get them like this:
file_1.ext file_10.ext file_2.ext file_3.ext file_40.ext
What I'm thinking of is like this:
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; }
But it doesn't work the way it should. Any suggestions? So this is a the callback-function for the usort funtion.
Shmuel.
