creating a single array out of an array of arrays

[mrmigu]

Hi,
Ive got an array of arrays:

Array
                (
                    [0] => Array
                        (
                            [0] => 278
                            [1] => 279
                            [2] => 280
                            [3] => 281
                        )

                [1] => Array
                    (
                        [0] => 282
                        [1] => 283
                        [2] => 284
                        [3] => 285
                    )

                [2] => Array
                    (
                        [0] => 286
                        [1] => 287
                        [2] => 288
                        [3] => 289
                    )


            )

and i would like to convert it into a single array, like:

Array
                (
                            [0] => 278
                            [1] => 279
                            [2] => 280
                            [3] => 281
                            [4] => 282
                            [5] => 283
                            [6] => 284
                            [7] => 285
                            [8] => 286
                            [9] => 287
                            [10] => 288
                            [11] => 289


            )

is there a function that will do this?

Im not at home so I can't test this, but maybe...?

<?php

  $array = // your multi dimensional array.
  $new = array();
  foreach ($array as $arr) {
    $new = array_merge($new, $arr);
  }

?>

Im sure its not this simple, but its an idea.

ok, i was just wondernig if there was a function that would do this for me.
your suggestion would work assuming that each element of $array was an array, but does not consider that they could be arrays of arrays. I guess Ill have to build a recursive function
