对 stdClass 对象使用 array_walk_recursive() [英] using array_walk_recursive() for stdClass objects

问题描述

我已经浏览了这里的一些答案，但似乎没有使用这种方法?

I have looked through a few answers on here but that don't seem to utilise this method?

我有一个项目数组，这些项目是对象.对象可以有一个键，它是 'children' 和 'children' 是一个对象数组等.

I have an array of items, and the items are objects. The object can have a key which is 'children' and 'children' is an array of objects etc.

有没有办法做到这一点?

Is there a way to achieve this?

示例:

    Array
    (
        [1] => stdClass Object

                    )

            )

        [2] => stdClass Object

            )

                    )

            )

推荐答案

在 $array 下分配对象数组.

Assign an array of objects under $array.

解决方案 1: json_encode 对象数组使其成为 json 然后将 json 转换为关联数组.

Solution 1: json_encode an array of objects to make it a json and then converting an json into associative array.

$result=json_decode(json_encode($array),true);
array_walk_recursive($result, function($value,$key){
    print_r($value);
    print_r($key);
});

解决方案 2: 迭代数组并将每个 object 类型转换为 array.

Solution 2: Iterating over array and type casting each object as array.

array_walk($array,function(&$value,$key){
    $value=(array) $value;
});
array_walk_recursive($array, function($value,$key){
    print_r($value);
    print_r($key);
});
