給定PHP中的2個數組，看起來像這樣...Array( [item1] => Array ( [myValues] => Array ( [1] => 5 [2] => 1 ) ) [item2] => Array ( [myValues] => Array ( [1] => 5 [2] => 1 ) ))Array( [item1] => Array ( [1] => 2 ) [item2] => Array ( [1] => 5 [2] => 1 ))array1array ( 'item1' => array ( 'myValues' => array ( 1 => 5, 2 => 1, ), ), 'item2' => array ( 'myValues' => array ( 1 => 5, 2 => 1, ), ), )將它們組合成如下所示的數組的最佳方法是什么？Array( [item1] => Array ( [myValues] => Array ( [1] => 5 [2] => 1 ) [myValues2] => Array ( [1] => 2 ) ) [item2] => Array ( [myValues] => Array ( [1] => 5 [2] => 1 ) [myValues2] => Array ( [1] => 5 [2] => 1 ) ))array2array ( 'item1' => array ( 1 => 2, ), 'item2' => array ( 1 => 5, 2 => 1, ), )我無法控制輸出，所以我認為我最好的方法是遍歷每個數組并將項目復制到一個新的數組中。我試過了...print_r(array_merge($a1,$a2));但這并沒有給我帶來我想要的結果。有人有例子嗎？

使用已知的第一級鍵和您發明的第二級鍵將 array2 數據推送到 array1 中。
代碼：（演示)
$array1 = array ( 'item1' => array ( 'myValues' => array ( 1 => 5, 2 => 1, ), ), 'item2' => array ( 'myValues' => array ( 1 => 5, 2 => 1, ), ), );
$array2 = array ( 'item1' => array ( 1 => 2, ), 'item2' => array ( 1 => 5, 2 => 1, ), );
foreach ($array2 as $key => $subarray) {
$array1[$key]['myValues2'] = $subarray;
}
var_export($array1);
輸出：
array (
'item1' =>
array (
'myValues' =>
array (
1 => 5,
2 => 1,
),
'myValues2' =>
array (
1 => 2,
),
),
'item2' =>
array (
'myValues' =>
array (
1 => 5,
2 => 1,
),
'myValues2' =>
array (
1 => 5,
2 => 1,
),
),
)
