組合兩個陣列數據

Question

我想合併兩個數組，其中每個具有相同的索引（ID這裏），但我不想刪除重複的ID （對不起，我的英語...）

First array name : $data['student'] 
Second array name: $data_student_name 

我有此陣列（$data['student']）

Array ([0] => Array ([id] => 16 [groups_id] => 1 [group_number] => 301) [1] => Array ([id] => 17 [groups_id] => 1 [group_number] => 301) [2] => Array ([id] => 18 [groups_id] => 1 [group_number] => 301) [3] => Array ([id] => 5 [groups_id] => 1 [group_number] => 301) [4] => Array ([id] => 14 [groups_id] => 1 [group_number] => 301) [5] => Array ([id] => 18 [groups_id] => 2 [group_number] => 434) [6] => Array ([id] => 19 [groups_id] => 2 [group_number] => 434) [7] => Array ([id] => 19 [groups_id] => 1 [group_number] => 301)) 

和此陣列$data_student_name

Array ([0] => Array ([id] => 5 [firstname] => Bruno [sex] => M) [1] => Array ([id] => 14 [firstname] => David [sex] => M) [2] => Array ([id] => 16 [firstname] => Élyse [sex] => F) [3] => Array ([id] => 17 [firstname] => Jean [sex] => M) [4] => Array ([id] => 18 [firstname] => Julie [sex] => F) [5] => Array ([id] => 19 [firstname] => Marie [sex] => F)) 

我結合我的兩個陣列，這

$data['group_student']= array(); 
    foreach ($data_student_name as $arr) { 
     $match = false; 
     foreach ($data['student'] as $arr2) { 
      if ($arr['id'] == $arr2['id']) { 
       $match = true; 
       $data['group_student'][] = array_merge($arr, $arr2); 
       break; 
      } 
     } 
     if (!$match) $data['group_student'][] = $arr; 
    } 

我optain這個結果（瑪麗不重複:(）（$data['group_student']）

Array ([0] => Array ([id] => 5 [firstname] => Bruno [sex] => M [groups_id] => 1 [group_number] => 301) [1] => Array ([id] => 14 [firstname] => David [sex] => M [groups_id] => 1 [group_number] => 301) [2] => Array ([id] => 16 [firstname] => Élyse [sex] => F [groups_id] => 1 [group_number] => 301) [3] => Array ([id] => 17 [firstname] => Jean [sex] => M [groups_id] => 1 [group_number] => 301) [4] => Array ([id] => 18 [firstname] => Julie [sex] => F [groups_id] => 1 [group_number] => 301) [5] => Array ([id] => 19 [firstname] => Marie [sex] => F [groups_id] => 2 [group_number] => 434) 1)) 

，我想這個結果（瑪麗被複制）

Array ([0] => Array ([id] => 5 [firstname] => Bruno [sex] => M [groups_id] => 1 [group_number] => 301) [1] => Array ([id] => 14 [firstname] => David [sex] => M [groups_id] => 1 [group_number] => 301) [2] => Array ([id] => 16 [firstname] => Élyse [sex] => F [groups_id] => 1 [group_number] => 301) [3] => Array ([id] => 17 [firstname] => Jean [sex] => M [groups_id] => 1 [group_number] => 301) [4] => Array ([id] => 18 [firstname] => Julie [sex] => F [groups_id] => 1 [group_number] => 301) [5] => Array ([id] => 19 [firstname] => Marie [sex] => F [groups_id] => 2 [group_number] => 434) [6] => Array ([id] => 19 [firstname] => Marie [sex] => F [groups_id] => 2 [group_number] => 301)) 

請問我該怎麼做？

Answer 1

嗨，你可以參考以下鏈接

Merge Array with duplicate values

     OR 

array_merge_recursive

感謝。+

Answer 2

使用array_merge

array_merge($arr1, $arr2);
