PHP遍历的问题？麻烦大家帮看一下。
我有个方法从mysql中取出一组数据，可是用while,for,foreach遍历出来的数据都多了，麻烦各位给看一下
1：取结果的方法

PHP code


function queryUserReport ( $userid ) {
            
            $resUserReportList = "" ;

            $queryUserReport = "Select reportId, userid, reportCheckId, email, createtime, constitutiontype From userreport Where userid = '".$userid."' " ;
            //echo "query:".$queryConstiutContent."
";

            $resUserReportList = $this->user_db->querySQL ( $queryUserReport ) ;
            
            if ($resUserReportList){
                $resUserReportList = $this->user_db->get_Array($resUserReportList);
                //print_r($resConstiutContent);
                return $resUserReportList ;
            } else {
                return $this->user_db->print_last_error(TRUE);
            }
            
            $this->user_db->Close() ;
            
        }

2：引用mysql的类

PHP code


 function querySQL($sql){
        $this->last_query=$sql;
        
        $result=mysql_query($sql);
        if (!$result){
            $this->last_error=mysql_error();
            return FALSE;
        }else {
            $this->row_count=mysql_num_rows($result);
            return $result;
        }
    }
    function get_Array($result){
        if (!$result){
            $this->last_error="Invalid resource identifier passed to get_Array() function.";
            return FALSE;
        }else {
            $row=mysql_fetch_array($result);
            if ($row==FALSE){
                $this->last_error=mysql_error();
                return FALSE;
            }else {
                return $row;
            }
        }
    }

3：取出的结果

PHP code


Array
(
    [0] => 3
    [reportId] => 3
    [1] => 414
    [userid] => 414
    [2] => 201209021468
    [reportCheckId] => 201209021468
    [3] => 
    [email] => 
    [4] => 2012-02-09 11:30:54
    [createtime] => 2012-02-09 11:30:54
    [5] => 1
    [constitutiontype] => 1
)

4：页面获取数据代码

PHP code


//获取数据
$arrayUserReportList = $dbConstituModel->queryUserReport($_SESSION['userid']);

while ( $arrayUserReportList = $arrayUserReportList ){
                        echo "";
                        echo "".$arrayUserReportList['reportId']." ";
                        echo "".$arrayUserReportList['createtime']." ";
                        echo "
查看报告 ";
                        echo "";
                    }

------解决方案--------------------
mysql_fetch_array 改成用mysql_fetch_assoc()
------解决方案--------------------
$arrayUserReportList = $dbConstituModel->queryUserReport($_SESSION['userid']);

echo "";
echo "".$arrayUserReportList['reportId']." ";
echo "".$arrayUserReportList['createtime']." ";
echo " 查看报告 ";
