Question

我在这里看了几个答案，但似乎没有使用这种方法？

我有一系列项目，项目是对象。对象可以有一个键，即“孩子”。和孩子们＆＃39;是一组对象等。

有没有办法实现这个目标？

示例：

    Array
    (
        [1] => stdClass Object
            (
                [id] => 1
                [name] => Steve King

                [parent] => 0
                [children] => Array
                    (
                    )

            )

                    (
                    )

            )

            (
                [id] => 4
                [name] => Ethan Watson

                    (
                    )

            )

        [5] => stdClass Object
            (
                [id] => 5
                [name] => Abigail Adams
                [image] => upload/shop/da1734277322fc3b2e84a9ddbcc2e2f1.jpg
                [parent] => 0
                [children] => Array
                    (
                    )

            )

Answer 1

在# begin .set_env HELLO="WORLD" GOODBYE="CRUEL_WORLD" # end .set_env WORLD ... CRUEL_WORLD下分配一组对象。

解决方案1： $array一系列对象，使其成为json_encode，然后将json转换为json。

associative array

解决方案2：对数组进行迭代，并将每个$result=json_decode(json_encode($array),true); array_walk_recursive($result, function($value,$key){ print_r($value); print_r($key); });类型转换为object。

array

Answer 2

您始终可以为某些数据结构实现自定义递归迭代器。它可以是更灵活的解决方案。例如：

class MyIterator extends \IteratorIterator implements 
\RecursiveIterator
{
    public function hasChildren()
    {
        $current = $this->current();

        if (is_array($current) and $this->key() === 'children') {
            return true;
        }

        return is_object($current);
    }

    public function getChildren()
    {
        /* $current is array (for key 'children') or \stdClass obj*/

        $current = $this->current();

        return new MyIterator(new \ArrayObject($current));
    }
}

$rii = new \RecursiveIteratorIterator(new MyIterator(new 
\ArrayObject($data)));

foreach ($rii as $key => $value) {
    print_r($key);
    print_r($value);
}

使用array_walk_recursive（）为stdClass对象
