试试这个 - ＆gt;

    $res="write your select query here" ;
    $result=mysql_query($res) or die("query fail to execute".mysql_error());
    $total=mysql_num_rows($result );
    if( $total<0){
     echo "no row found";
     }
    else{
     while($row=mysql_fetch_array($result))
     {
   // some code}

无法使用PHP中的用户名和密码登录
