根据其值从数组中删除元素? [英] remove element from array based on its value?

问题描述

我有一个包含键和值的常规数组.

i've got a regular array with keys and values.

是否有一种简单的方法可以根据其值删除数组元素，或者我是否需要foreach循环遍历并检查每个值以删除它?

is there a simple way to remove the array element based on its value or do i have to foreach-loop it through and check every value to remove it?

PHP 5.3示例从数组$ a中删除"foo":

PHP 5.3 example to remove "foo" from array $a:

<?php
$a = array("foo", "bar");
$a = array_filter($a, function($v) { return $v != "foo"; });
?>

第二个参数可以是任何类型的PHP回调(例如，函数名称为字符串).如果搜索值不恒定，也可以使用函数生成函数.

The second parameter can be any kind of PHP callback (e.g., name of function as a string). You could also use a function generating function if the search value is not constant.
