$pieces = array_chunk($array, ceil(count($array) / 2));

If you want them in separate variables (instead of a multi-dimensional array), use list:

list($array1, $array2) = array_chunk($array, ceil(count($array) / 2));

you have to cast it to int: $pieces = array_chunk($array, (int) ceil(count($array) / 2));

array_slice works well as long as you know how many elements you want in each array:

$array1 = array_slice($array, 0, 3);
$array2 = array_slice($array, 3, 3);

Thanks, more appropriate to me since I needed my array to split at one specific index and not in more than 2 chunks

Heads up, I used array_splice by mistake instead of array_slice and got stuck wondering why the original array was changing!
