Question

我想组合两个数组，每个数组都有相同的索引（此处为ID），但我不想删除重复的ID （抱歉我的英文...）

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

我有这个数组（$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 ) )

和此数组$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 ) )

我将我的两个数组与此

组合在一起

  $data['group_student']= array(); 
    foreach ($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; 
    }

我得到了这个结果（玛丽没有重复:(）（$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 ))

我想要这个结果（玛丽是重复的）

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 ))

我该怎么办呢？

Answer 1

嗨，您可以参考以下链接

Merge Array with duplicate values

OR

array_merge_recursive

感谢。+

Answer 2

使用array_merge

array_merge($arr1, $arr2);

合并两个数据数组
