本文章给大家整一个php 多维数组的排序实现代码，我们在实际编码中将会用到PHP函数array_multisort()来实现这一复杂的排序，有需要了解的朋友可参考。

如数组

代码如下

复制代码

Array
(
   [0] => Array
       (
           [id] => 1146
           [orderid] => 3
       )

   [1] => Array
       (
           [id] => 1149
           [orderid] => 2
       )

   [2] => Array
       (
           [id] => 170
           [orderid] => 4
       )

   [3] => Array
       (
           [id] => 1121
           [orderid] => 3
       )

   [4] => Array
       (
           [id] => 1120
           [orderid] => 7
       )

)

这么一个数据，想按orderid来排序。找不到内置的php函数，网上搜索了下，发现如下方法：

代码如下	复制代码
$asc_func = create_function('$a,$b',' $k = "orderid"; if($a[$k] == $b[$k]) return 0; return $a[$k]>$b[$k]?1:-1; '); usort($arrs,$asc_func);

$arrs是原数组，$k="orderid"是要排序的字段

后来对上面代码进行了升级

代码如下

复制代码

function sysSortArray($ArrayData,$KeyName1,$SortOrder1 = "SORT_ASC",$SortType1 = "SORT_REGULAR")
{
    if(!is_array($ArrayData))
    {
        return $ArrayData;
    }

// Get args number.
$ArgCount = func_num_args();

    // Get keys to sort by and put them to SortRule array.
    for($I = 1;$I     {
        $Arg = func_get_arg($I);
        if(!eregi("SORT",$Arg))
        {
            $KeyNameList[] = $Arg;
            $SortRule[]    = '$'.$Arg;
        }
        else
        {
            $SortRule[]    = $Arg;
        }
    }

    // Get the values according to the keys and put them to array.
    foreach($ArrayData AS $Key => $Info)
    {
        foreach($KeyNameList AS $KeyName)
        {
            ${$KeyName}[$Key] = $Info[$KeyName];
        }
    }

    // Create the eval string and eval it.
    $EvalString = 'array_multisort('.join(",",$SortRule).',$ArrayData);';
    eval ($EvalString);
    return $ArrayData;
}
