Parse error: syntax error, unexpected $end in D:\wamp\www\bbs\login.php on line 56


------解决方案--------------------
总共才 48 行代码，拿来 56 行出错？
------解决方案--------------------
错误比较明确啊，$end这个变量有问题啊，先查一下，这个变量在哪里出现了啊，估计要查一下coon.php
------解决方案--------------------
if($_GET[out]){

$_GET['OUT']'去掉可以不？
------解决方案--------------------
不解释了，把我的代码拷贝下吧，括号匹配不合适。
