php连接mysql查询一条数据
数据库中有张表有主键pmcode还有其他属性如图:
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,不存在的话返回"不存在",然后通过拼接xml的形式发送出去,代码如下:

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

可是就算输入正确的pmcode都娶不到想要的数据,求大神修改
