mysqlphp查询

数据库中有张表有主键pmcode还有其他属性,我现在想通过pmcode判断某个用户是否存在,存在的话将其信息取出,代码如下:

<code> //拆分发来的信息得到会员卡号            $arry=explode("+",$form_Content);            $memberid =$arry[1];              //连接数据库            $link=mysql_connect(SAE_MYSQL_HOST_M.':'.SAE_MYSQL_PORT,SAE_MYSQL_USER,SAE_MYSQL_PASS);               if($link) {                   mysql_select_db(SAE_MYSQL_DB,$link);                    //查询数据                   $result1=mysql_query("select * from numbers where pmcode = '".$memberid."';");                 $num_result = mysql_num_rows($result1);                   if($num_result==1){                       //   $row= $result1->fetch_assoc();                       $row=mysql_fetch_row($result1);                        $result_str="您的会员--信息如下:\n\n卡号:$row[pmcode].\n姓名:.$row[names].\n等级:.$row[4].\n积分:$a[5]";                         $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType,$result_str);                         echo $resultStr;                                           exit;                   }else{                     $msgType = "text";                    $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType,"--select * from numbers where pmcode = '".$memberid."'");                      echo $resultStr;                                      exit;                   }        }   else{             echo "连接数据库失败".mysql_error;            }                           mysql_close($link);        }</code>

可是不管怎样测试都取不到数据,求大神修改。
