我知道之前已发布过，但我无法让它为我工作：我不知道为什么！但是任何我的数组$服务器都是这样的
Array

我想重新安排阵列并将其重新安装到$服务器中，但按$服务器顺序排列[x] [1]
所以，如果奇数是（第一个对象是8），我希望用最小的数字1对它进行排序，移动到最大的数字！
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");
?>
但它似乎没有用！
由于
答案 0 :(得分：1)
您的cmp错了。 $a和$b是
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];
}
