合併兩個類似的多維數組到一個

Question

我有此數組：

$arr1 = array (
    array (
     array (
      'correct' => FALSE, 
      'answer' => 'false answer1' 
     ), 
     array (
      'correct' => FALSE, 
      'answer' => 'false answer2' 
     ), 
     array (
      'correct' => FALSE, 
      'answer' => 'false answer3' 
     ) 
    )); 

這陣：

$arr2 = array (
    array ( 
     array (
      'correct' => TRUE, 
      'answer' => 'correct answer' 
     ) 
    )); 

我所要的輸出是：

$output = array (
    array (
     array (
      'correct' => FALSE, 
      'answer' => 'false answer1' 
     ), 
     array (
      'correct' => FALSE, 
      'answer' => 'false answer2' 
     ), 
     array (
      'correct' => FALSE, 
      'answer' => 'false answer3' 
     ),     
     array (
      'correct' => TRUE, 
      'answer' => 'correct answer' 
     ) 
    )); 

我試過using array_merge ，array_merge_recursive，但它合併它不是我想要它（它只是增加了底部的值而不是placi將它們正確地插入每個陣列）。我也看到了類似的問題，但它並沒有幫助我（仍將底部的值合併，而不是我希望它們如何）。

有什麼建議嗎？

Answer 1

試試這個，

array_merge($arr1[0], $arr2[0]); 

Answer 2

試試這個

$array[] = array_merge($arr1[0],$arr2[0]); 
print_r($array); 

Codepad

輸出

Array 
(
[0] => Array 
    (
     [0] => Array 
      (
       [correct] => 
       [answer] => false answer1 
      ) 

     [1] => Array 
      (
       [correct] => 
       [answer] => false answer2 
      ) 

     [2] => Array 
      (
       [correct] => 
       [answer] => false answer3 
      ) 

     [3] => Array 
      (
       [correct] => 1 
       [answer] => correct answer 
      ) 
    ) 
) 

Answer 3

$arr1= array (
       array (
         array (
            'correct' => FALSE, 
            'answer' => 'false answer1' 
         ), 
         array (
            'correct' => FALSE, 
            'answer' => 'false answer2' 
         ), 
         array (
            'correct' => FALSE, 
            'answer' => 'false answer3' 
         ) 
       ) 
       ); 
     $arr2= array (
        array ( 
         array (
            'correct' => TRUE, 
            'answer' => 'correct answer' 
         ) 
       ) 
       ); 

     $result=array(array_merge($arr1[0],$arr2[0])); 
     print_r($result); 

輸出

Array 
(
    [0] => Array 
    (
     [0] => Array 
      (
       [correct] => 
       [answer] => false answer1 
      ) 

     [1] => Array 
      (
       [correct] => 
       [answer] => false answer2 
      ) 

     [2] => Array 
      (
       [correct] => 
       [answer] => false answer3 
      ) 

     [3] => Array 
      (
       [correct] => 1 
       [answer] => correct answer 
      ) 

    )
