php 多維陣列的排序實現代碼

如數組

代碼如下

複製代碼

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        ) )

這麼一個資料，想按orderid來排序。找不到內建的php函數，網上搜尋了下，發現如下方法：

代碼如下	複製代碼
$asc_func  =  create_function('$a,$b','  $k  =  "orderid"; if($a[$k]  ==  $b[$k])  return  0;  return  $a[$k]>$b[$k]?1:-1;  ');  usort($arrs,$asc_func);

$arrs是原數組，$k="orderid"是要排序的欄位

後來對上面代碼進行了升級

代碼如下

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 < $ArgCount;$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; }
