替换数组php

我有两个数组。我的问题是，如何将lang_1中的数组替换为lang_2中的数组，其中status_answer=2 only

首先搜索lang_2以查找所需的元素：

[lang_1] => Array
    (
        [0] => Array
            (
                [answer] => satu
                [status_answer] => 2
                [key_array] => 0
                [language] => lang_1
            )

        [1] => Array
            (
                [answer] => dua_en
                [status_answer] => 3
                [key_array] => 
                [language] => lang_1
            )

        [2] => Array
            (
                [answer] => lima
                [status_answer] => 3
                [key_array] => 
                [language] => lang_1
            )

        [3] => Array
            (
                [answer] => enam
                [status_answer] => 3
                [key_array] => 
                [language] => lang_1
            )

    )

[lang_2] => Array
    (
        [0] => Array
            (
                [answer] => satu
                [status_answer] => 3
                [key_array] => 
                [language] => lang_2
            )

        [1] => Array
            (
                [answer] => dua_en
                [status_answer] => 2
                [key_array] => 1
                [language] => lang_2
            )

        [2] => Array
            (
                [answer] => lima
                [status_answer] => 3
                [key_array] => 
                [language] => lang_2
            )

        [3] => Array
            (
                [answer] => enam
                [status_answer] => 3
                [key_array] => 
                [language] => lang_2
            )

    )

然后在lang_1中搜索要替换的元素：

foreach ($array['lang_2'] as $el) {
    if ($el['status_answer'] == 2) {
        $replacement = $el;
        break;
    }
}

---

如果lang_2中有多个元素的状态为2会怎么样？这不会发生。。但如果真的发生了。只要取lang_2中的值。只需将lang_2替换为lang_1，就可以编写一个循环，在lang_2中查找具有所需值的元素。然后编写一个循环，在lang_1中找到要替换的元素，并替换它。

foreach ($array['lang_1'] as &$el) {
    if ($el['status_answer'] == 2) {
        $el = $replacement;
    }
}
