How to use a returned PHP array inside an array itself? -

i create php array, of elements replaced elements of array returned function. example, create following array:

$aarray = array(     0x01,      0x10,      foo(1234),      0x03,      foo(445),      ... ) 

here, foo function returning simple php array. is, of course, like

(     [0] => 1     [1] => 16     [2] => array        (          [1] => 2          [2] => 4        )     [3] => 03     [4] => array       .... 

but want include returned values function directly array, create like: ( [0] => 1 [1] => 16 [2] => 2 [3] => 4 [4] => 03 [5] => 3 ....

is possible in simple way, without having construct array array_merge?

p.s: above example not working example, showing want do. content of function foo irrelevant.

this closest thing can match need

$aarray = array_flat(     0x01,      0x10,      foo(1234),      0x03,      foo(445) ); 

and here code array_flat.

function array_flat() {     $array  = func_get_args()     $result = array();     foreach ($array $value) {         is_array($value) || $value = array($value);                            foreach ($value $dvalue) {             $result[] = $dvalue;         }     }      return $result; }
