您好！修改程序中变量的写法，将程序中获取全局变量的写法由“$kt_lbes”修改为“$_POST[kt_lbes]”,这是获取post传递的变量。如果是get方法的，应使用$_GET[变量名]。下面的代码中我修改了$kt_lbes=$_POST[kt_lbes];或$kt_lbes=$_get[kt_lbes];还是不行啊！跟以前错误一样啊！请问题是什么原因啊！
<?php session_start();include("conn/conn.php");
if($_SESSION[online_number]!=""){
$kt_lbes=$_POST[kt_lbes];
//$kt_lbes=$_GET[kt_lbes];
//$_POST[kt_lbes];
$kt_small_lb=$_POST[kt_small_lb];

$query=mysql_query("select * from tb_user where online_number='$_SESSION[online_number]' and online_pt='1'");
$result=mysql_num_rows($query);
if($result==0){
?>

读者您好：
您多次发表评论说您的这个程序运行不了，请问，您有按照我给您说的更改php.ini中的文件配置了吗？
另外，您可以在数据处理页应用echo语句输出$_POST[kt_lbes]试一下，如果接收到了值，说明文件配置成功了，如果没有接收到值，说明是您配置文件的事，按照我前几次为您回复修改配置文件就可以了。
