拆分二维数组PHP

Question

I have a 2d array as such :

   Array
        (
          [0] => Array([nid] => 5),
          [1] => Array([nid] => 6),
          [2] => Array([nid] => 7),......

I want to split the array by key into two parts. For example I want to split the array at key = 1. I need the result as two arrays arr1 holding key 0 & 1 and arr2 holding key 2 . Can anyone help me out?

Answer 1

$arr1 = array_slice($input, 0, 2); 
//array holding elements and keys of array [0] and [1]
$arr2 = array_slice($input, 2);  
//array holding elements and keys of array [2] to n
