数组更高一级

Question

我有这个数组：

[@attributes] => Array
                (
                    [url] => 
                    [navigation] => true
                    [template] => home
                )

            [@children] => Array
                (
                    [0] => Array
                        (
                            [name] => Home
                        )

                    [1] => Array
                        (
                            [desc] => Lorem ipsum dolor
                        )

                    [2] => Array
                        (
                            [@children] => Array......

我需要它来代替：

[@attributes] => Array
                (
                    [url] => 
                    [navigation] => true
                    [template] => home
                )

            [@children] => Array
                (
                      [name] => Home
                      [desc] => Lorem ipsum dolor
                      [@children] => Array......

我无法改变这个数组实际构建的方式，所以我需要基本上摆脱每个项目在他们自己的数组中，它们都应该嵌套在子项下。

提前致谢

Answer 1

您可以使用call_user_func_array和array_merge执行此操作：

$arr['@children'] = call_user_func_array('array_merge', $arr['@children']);

这将使用array_merge数组作为参数调用$arr['@children']。

Answer 2

首先遍历子节点，将每个值存储在一个新数组中，然后覆盖它：

$newChildren = array();
foreach ($arr['@attributes']['@children'] as $property) {
  foreach ($property as $key => $val) {
    $newChildren[$key] = $val;
  }
}
$arr['@attributes']['@children'] = $newChildren;

如果这些值的嵌套深度超过一个级别（我看到另一个@children键/数组），您可以将它放在一个函数中并递归调用它。

Answer 3

尝试一下......

foreach (@attributes[@children] as $arrayVal)
{
   foreach($arrayVal as $key=>$val)
        @mySimpleArray[] = $val

}
