如何根据键删除数组元素? [英] How to delete an array element based on key?

问题描述

可能的重复:
如何从php中的数组中删除一个元素?

例如

Array(      
    [0] => Array
        (
            [0] => hello
            [1] => open
        )

    [1] => Array
        (
            [0] => good
            [1] => center
        )

    [2] => Array
        (
            [0] => hello
            [1] => close
        )
)

我想删除key为1的元素，操作后:

I want to delete the element which key is 1, after the operation:

Array(
    [0] => Array
        (
            [0] => hello
            [1] => open
        )

    [2] => Array
        (
            [0] => hello
            [1] => close
        )
)

推荐答案

PHP

unset($array[1]);
