Sortera

Testa det här:

$array[0] = "age2";
$array[1] = "name8";
$array[3] = "adress3";
$array[4] = "gender6";

function cmp ($a, $b) { 
   $a = preg_replace("/[^\d]/", "", $a);
   $b = preg_replace("/[^\d]/", "", $b);
   if ($a == $b) return 0; 
   return ($a < $b) ? -1 : 1; 
}

usort ($array, "cmp");
