本文實(shí)例講述了php自定義函數(shù)實(shí)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(duì)大家PHP程序設(shè)計(jì)有所幫助。
