Hi, I have 2 arrays: Array (

          [0] => Array (
                               [0] => 28                                [1] => Music
                             )            [1] => Array (                                 [0] => 5                                 [1] => Books                              )           )

and Array (

          [0] => aaa
          [1] => bbb
          )

I want to join this two array and the result must be loke this: Array (

          [0] => Array (
                               [0] => 28                                [1] => Music
                               [2] => aaa
                             )            [1] => Array (                                 [0] => 5                                 [1] => Books
                                [2] => bbb                              )           )

Thanks in advance for your help

In this specific example, I think this would work: <? for ($i = 0; $i < count($second_array); $i++) { array_push($first_array[$i], $second_array[$i]); } ?> That's not terribly flexible, though. Is this used in a more generalized sense, or is it just this specific instance?

This variation of Mike's solution will allow the array keys to be non-numeric and/or non-incrementing. <?php foreach($second_array as $key=>$value) { if(array_key_exists($key, $first_array)) {

     array_push($first_array[$key], $value);

} else {

     print 'ERROR:  Key '.$key.' does not exist in array $first_array.\n';
     // or alternatively to add a new sub-array to $first_array
     // $first_array[$key] = array($value);

} } ?> --Bob
