Use array_chunk:
使用array_chunk：
$pieces = array_chunk($array, ceil(count($array) / 2));
If you want them in separate variables (instead of a multi-dimensional array), use list:
如果您希望它们在单独的变量中（而不是多维数组），请使用list：
list($array1, $array2) = array_chunk($array, ceil(count($array) / 2));

array_sliceworks well as long as you know how many elements you want in each array:
array_slice只要您知道每个数组中需要多少个元素，就可以很好地工作：
$array1 = array_slice($array, 0, 3);
$array2 = array_slice($array, 3, 3);
