php - array_merge 和 array1 + array2 之间的妥协

Question

我想联合两个数组，覆盖重复的键，但不想重新索引所有索引。是否有一些功能可以做到这一点？

我需要两者的联合结构，因此每个键中的内容无关紧要。

阵列 1：

[820]
   [name1]
      [id] = "My Name"
   [name2]
      [id] = "Your Name"
[830]
   [id] = "Mothers Name"

阵列 2：

[815]
   [name1]
      [id] = "IDs Name"
[820]
   [name1]
      [id] = "Names Name"
   [id] = "Last ID ID"

结果应该是

[815]
   [name1]
      [id] = //does not matter
[820]
   [name1]
      [id] = //does not matter
   [name2]
      [id] = //does not matter
   [id] = //does not matter
[830]
   [id] = //does not matter

Answer 1

$result = array();
foreach ($array1 as $key => $value){
    if(isset($array2[$key]))
        $result[$key] = array_merge($value, $array2[$key]);
    else 
        $result[$key] = $value;
}
foreach ($array2 as $key => $value){
    if(isset($array1[$key]))
        $result[$key] = array_merge($value, $array1[$key]);
    else 
        $result[$key] = $value;
}
