Hello, I have this piece of code that works as intended: $chars = array('1','2','3'); $cnt = count($chars); $strings = array(); for ($f = 0; $f < $cnt; $f++) { for ($s = 0; $s < $cnt; $s++) { for ($t= 0; $t < $cnt; $t++) { $strings[] = $chars[$f] . $chars[$s] . $chars[$t]; } } } print_r($strings); The problem i'm facing is that i want to transform it in a function where i pass the chars and the nr of elements in the permutation in the above code if i want more elements ill duplicate the for loop and so on. For example i'm trying to create a function like: function perm($chars,$nrElements){ } thank you in advance
