二维数组排序

 <?
                    $names = array();
                    foreach ($list as $key => $row) {
                        $names[$row['uid']] = $row['name'];
                    }
                   array_multisort($names);
                   foreach($names as $k=>$v){
                      $sel=$v==$_POST['name']?'selected':'';
                       echo "<option value='$v' $sel>".$v."(".$k.")</option>";
                  }
                 ?>

很简单，不过不会的估计要思考半天
