Solution to array combination algorithm

Algorithm for array combination

PHP Code

  
   Array (2) {  [8] = = Array (2) {    [0] = = string (2) ""    [1] = = string (2) ""  }  [9] = = Array (2) {    [0] = = string (2) "" "    [1] = = string (2)" "}  }

A combination of 2 arrays with multiple arrays? Master, please.

It's a question of Cartesian product.

PHP code

 $ar = Array (8 + = Array (' 9 ', ' + '), + = = Array (  ' + '),;p Rint_r (Descartes ($ar)), function Descartes () {$t = Func_get_args ();   if (Func_num_args () = = 1) return Call_user_func_array (__function__, $t [0]);  $a = Array_shift ($t);  if (! Is_array ($a)) $a = array ($a);  $a = Array_chunk ($a, 1);    do {$r = array ();    $b = Array_shift ($t);    if (! Is_array ($b)) $b = Array ($b);    foreach ($a as $p) foreach (Array_chunk ($b, 1) as $q) $r [] = Array_merge ($p, $q);  $a = $r;  }while ($t); return $r;}
