代码安全隐患(散分)
刚发现自己写的一段验证代码有严重的安全隐患,请大家指教。代码的目的是先通过判断SESSION变量是否注册及其值是否合法,如果验证失败就跳转到登录页面,如果成功才继续往下执行:

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?phpsession_start ();//$_SESSION['gid'] 是用户登录成功时注册的变量,值1代表管理员组if (!isset($_SESSION['gid']) || ($_SESSION['gid'] != 1)) {  header("location:login.php?".SID);}//do some thing here?>
Copy after login


我以为第一步验证失败后,页面就马上跳转到login.php页了,但实际发现验证没有通过的情况下,也会执行一部分的后续代码(好像没有完整执行),不知道是不是页面跳转需要一定的时间,就在执行跳转这段时间里面又执行了后续的一部分代码?为什么遇到header()函数后不是马上跳转呢?

------解决方案--------------------
session_start(); 
if( 1 != $_SESSION['gid'])) { 
header("location:login.php?".SID); 
exit(); 


//do some thing here 
?>
