按键值排序的PHP顺序数组

我知道以前有人贴过，但我无法让它为我工作：it’我不知道为什么！但无论如何，我的array$服务器看起来是这样的

Array
(
    [0] => Array
        (
            [0] => Dell PowerEdge R210 II
            [1] => 8
            [2] => Array

                    [2] => Price

                    [10] => OrderLink
                )

        )

)

我希望重新安排阵列并将其放回$servers中，但顺序为$servers[x][1]

所以，当单数为（第一个对象是8）时，我希望它以最小的数字第一次排序，移动到最大

非常感谢

ps我试过这个

<?php
function cmp($a, $b)
{
    if ($a == $b) {
        return 0;
    }
    return ($a < $b) ? -1 : 1;
}

$a = array(3, 2, 5, 6, 1);

usort($servers, "cmp");
?>

但它似乎不起作用

谢谢

你的

cmp

错了

$a

和

$b

是类似的数组

Array
    (
        [0] => Dell PowerEdge R210 II 6
        [1] => 6
        [2] => Array
            (
                [0] => 6
                [1] => Sock
                [2] => Price
                [3] => ImageURL
                [4] => CPU
                [5] => Memory
                [6] => HDD
                [7] => Bandwidth
                [8] => OS
                [9] => Upgrades
                [10] => OrderLink
            )

    )

您必须将

$a[1]

与

$b[1]

进行比较：

function cmp($a, $b) {
    return $a[1] - $b[1];
}

---

仔细阅读。手册中也有一些很好的例子。您的

cmp

函数需要检查

$a[1]

与

$b[1]

的值。
