Question

陣列分成兩個相同的陣列我有一個數組，看起來像這樣：

MyArray (
    [0] => Array (
          [board_id] => 1047999 
          [added_date] => 2013-02-28 11:14:02 
          [type] => 4 
          ) 
    [1] => Array (
          [board_id] => 1047999 
          [added_date] => 2013-02-28 11:14:02 
          [type] => 1 
         ) 
    [2] => Array (
          [board_id] => 1047999 
          [added_date] => 2013-02-28 11:14:02 
          [type] => 4 
         ) 
    [3] => Array (
          [board_id] => 1047999 
          [added_date] => 2013-02-28 11:14:02 
          [type] => 1 
         ) 
) 

我如何通過type拆分該陣列，並保持完全相同的陣列結構？即我會有兩個子陣列的MyArrayT4和兩個子陣列的MyArrayT1？

TIA！

使用array_filter這樣 EDIT用array_values重置

$filtering = function($type) use($your_array) { 
    $filtered = array_filter($your_array, function($r) use($type) { 
     return $r['type'] == $type; 
    }); 

    return array_values($filtered); 
}; 


$array_1 = $filtering->__invoke('4'); 
$array_2 = $filtering->__invoke('1');
