基于价值的多维数组元素删除 [英] Delete element from multidimensional-array based on value

问题描述

我试图删除基于值多维数组元素。在这种情况下，如果一个子阵列的主要年的值是2011我想该子阵列出来。

只是为了记录：我运行PHP 5.2

我的数组是这样的：

 阵列

）
 

解决方案

试试这个：

 函数removeElementWithValue（$数组$关键，$值）{
     的foreach（$数组作为$子项= GT; $子阵列）{
          如果（$子数组[$关键] == $值）{
               未设置（$数组[$子键]）;
          }
     }
     返回$阵列;
}
 

然后，你会说它是这样的：

  $阵列= removeElementWithValue（$数组，年，2011年）;
 

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.

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

My array looks like this:

Array

    [0] => Array

            [filmId] => 61359

            [genres_text] => Actie / Thriller
            [duration] => 96
        )
)

解决方案

Try this:

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

Then you would call it like this:

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