php自定義函數(shù)實現(xiàn)二維數(shù)組排序功能

    本文實例講述了php自定義函數(shù)實現(xiàn)二維數(shù)組排序功能。分享給大家供大家參考，具體如下：
    /**作用: 二維數(shù)組排序函數(shù),支持多鍵名排序
     * 返回: 排序好的數(shù)組
     * 使用: array_msort(數(shù)組,需要排序的鍵名,排序方式);
     * 例子: array_msort($cflist,"chapter_orderid","SORT_ASC");
     *    array_msort($arr,"name","SORT_ASC","type","SORT_DESC","size","SORT_ASC","SORT_STRING");
     */
    function array_msort($ArrayData,$KeyName1,$SortOrder1 = "SORT_ASC",$SortType1 = "SORT_REGULAR") {
      if(!is_array($ArrayData)) {
        return $ArrayData;
      }
      // 獲取參數(shù)數(shù)量.
      $ArgCount = func_num_args();
      // 排序,并放置到SortRule數(shù)組
      for($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;
    }
    希望本文所述對大家PHP程序設計有所幫助。
