Example Digital:

$data = array( 1,2,3,4,5,6,7,8,9,10, 100 );
       
$util = SystemUtils::getInstance();
$res = $util->split( $data, 2 );
echo '<pre>';
var_dump( $res );
echo '</pre>';
exit;

Sample results:

array(6) {
  [0]=>
  array(2) {
    [0]=>
    int(1)
    [1]=>
    int(2)
  }
  [1]=>
  array(2) {
    [0]=>
    int(3)
    [1]=>
    int(4)
  }
  [2]=>
  array(2) {
    [0]=>
    int(5)
    [1]=>
    int(6)
  }
  [3]=>
  array(2) {
    [0]=>
    int(7)
    [1]=>
    int(8)
  }
  [4]=>
  array(2) {
    [0]=>
    int(9)
    [1]=>
    int(10 ) 
  } 
  [ . 5 ] => 
  Array ( . 1 ) { 
    [ 0 ] =>
     int ( 100 ) 
  } 
}
