 阵列（

            [0] =＆GT;你好
            [1] =＆GT;打开
        ）    [1] =＆GT;排列

            [1] =＆GT;中央
        ）    [2] =＆GT;排列

For instance,

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

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

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

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
        )
)

解决方案

PHP

unset($array[1]);
