我有這兩個數組。我的問題是，我怎麼能在lang_1與數組中lang_2取代數組，其中status_answer = 2只爲元素替換數組php

如果'lang_2'中有多個元素，其中'status_answer = 2'，該怎麼辦？ – Barmar 2015-04-03 03:18:27

這不會發生..但如果發生。只需要lang_2中的值。只需要將lang_2替換爲lang_1 – 2015-04-03 03:43:23

因此，編寫一個循環來查找具有所需值的'lang_2'中的元素。然後編寫一個循環，找到要替換的'lang_1'中的元素，並將其替換。 – Barmar 2015-04-03 03:44:35

首先搜索lang_2你想：

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

然後搜索lang_1您要更換元素：

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