合并数组数组，数组成以上

Question

在PHP我有一个像数组以下几点：

Array 
(
    [items] => Array 
     (
      [0] => Array 
       (
        [attr_1] => value 
        [attr_2] => value 
        [attr_3] => value 
        [other_array] => Array 
         (
          [attr_4] => value 
          [attr_5] => value 
          [attr_6] => value 
         ) 
        [attr_7] => value 
        [attr_8] => value 
       ) 

      [1] => Array 
       (
        [attr_1] => value 
        [attr_2] => value 
        [attr_3] => value 
        [other_array] => Array 
         (
          [attr_4] => value 
          [attr_5] => value 
          [attr_6] => value 
         ) 
        [attr_7] => value 
        [attr_8] => value 
       ) 
     ) 
) 

也许很简单，但它无法得到它的工作..我想合并other_array进入阵列上面，所以输出将变成：

Array 
(
    [items] => Array 
     (
      [0] => Array 
       (
        [attr_1] => value 
        [attr_2] => value 
        [attr_3] => value 
        [attr_4] => value 
        [attr_5] => value 
        [attr_6] => value 
        [attr_7] => value 
        [attr_8] => value 
       ) 

      [1] => Array 
       (
        [attr_1] => value 
        [attr_2] => value 
        [attr_3] => value 
        [attr_4] => value 
        [attr_5] => value 
        [attr_6] => value 
        [attr_7] => value 
        [attr_8] => value 
       ) 
     ) 
) 

有没有PHP函数，或者其他快速的方法来实现这个？

你必须unset()的'other_array'，这样一个办法：

foreach($array['items'] as &$v) { 
    $v = array_merge($v, $v['other_array']); 
    unset($v['other_array']); 
}
