我有这个两阵。我的问题是，我怎么能在 LANG_2 ，其中 status_answer =替换 lang_1 与数组的数组2 仅

I have this two array. My problem is, how i can replace array in lang_1 with array in lang_2 where status_answer = 2 only

推荐答案

首先搜索 LANG_2 您需要的元素：

First search lang_2 for the element you want:

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

然后搜索 lang_1 你要替换的元素：

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