I do a simple user login system to realize that your session has expired please re-login this feature:
1. Landing page, the user first login, I'm sure there's no hint .。
2. The user login success, the corresponding page, and soon the session expired, forced to jump to the landing page, but also prompted a word to the user: your session has expired please re-login, how does this come true?

You can set the length of time the cookie expires.

Session sets the expiration time of the user ID. Setting a cookie to fail is often used to determine user page jumps

Upstairs set sesion time should not be able to achieve the landlord's purpose, because the value is not the same as no login status, and can not be detected, you may set a variable in the SESSION to save time, such as $_session[' exptime '] = Now () +3600 To specify a time-out after 3,600 seconds, and then check the login status to determine if $_session[' exptime ' is greater than now () to make a judgment!

I think it should not be detected in the login location. Should be detected at the next operation,
Log in after completion of the next time, such as 10 minutes to deposit $_session[' Exptime ' =now () +600
Then each action is to detect whether the login status
Like what
if (!isset ($_session[' username '))
------Solution--------------------
$_session[' username ']) {
$_session[' tips ']= "";
。。。 Jump Login Page
}else{
if ($_session[' Exptime ') <>
$_session[' username ']= "//Clear off the original state
$_session[' tips ']= "Your session has expired please re-login";
。。。 Jump Sign-in page: and output $_session[' tips ']
}
}
$_session[' Exptime ']= finish () +600;
Reset $_session[' Exptime ' after detection is complete
