根据值从多维数组中删除元素 [英] Delete element from multidimensional-array based on value

问题描述

我正在尝试根据值从多维数组中删除元素.在这种情况下，如果子数组的键 'year' 的值为 2011，我希望该子数组退出.

I'm trying to delete elements from a multidimensional-array based on a value. In this case if a sub-array's key 'year' has the value 2011 I want that sub-array out.

只是为了记录:我正在运行 PHP 5.2.

Just for the record: i'm running PHP 5.2.

我的数组如下所示:

推荐答案

试试这个:

function removeElementWithValue($array, $key, $value){
     foreach($array as $subKey => $subArray){
          if($subArray[$key] == $value){
               unset($array[$subKey]);
          }
     }
     return $array;
}

那么你可以这样称呼它:

Then you would call it like this:

$array = removeElementWithValue($array, "year", 2011);
