Class for managing HTTP sessions

Provides access to session-state values as well as session-level settings and lifetime management methods. Based on the standart PHP session handling mechanism it provides for you more advanced features such as database container, idle and expire timeouts, etc.

Expample 1:

 // Setting some options and detecting of a new session

 HTTP_Session2::useCookies(false);
 HTTP_Session2::start('MySessionID');
 HTTP_Session2::set('variable', 'The string');
 if (HTTP_Session2::isNew()) {
     echo 'new session was created with the current request';
     $visitors++; // Increase visitors count
 }
 
 //HTTP_Session2::regenerateId();

Example 2:

 // Using database container

 HTTP_Session2::setContainer('DB');
 HTTP_Session2::start();

Example 3:

 // Setting timeouts

 HTTP_Session2::start();
 HTTP_Session2::setExpire(time() + 60 * 60); // expires in one hour
 HTTP_Session2::setIdle(10 * 60);            // idles in ten minutes
 if (HTTP_Session2::isExpired()) {
     // expired
     echo('Your session is expired!');
     HTTP_Session2::destroy();
 }
 if (HTTP_Session2::isIdle()) {
     // idle
     echo('You've been idle for too long!');
     HTTP_Session2::destroy();
 }
 HTTP_Session2::updateIdle();

[ Top ]

name [line 292]

string name(
[string

See: session_name()
Access: public

Parameters:

string $name — New name of a sesion

[ Top ]

pause [line 222]

void pause(
)

Writes session data and ends session

Session data is usually stored after your script terminated without the need to call HTTP_Session2::stop(), but as session data is locked to prevent concurrent writes only one script may operate on a session at any time. When using framesets together with sessions you will experience the frames loading one by one due to this locking. You can reduce the time needed to load all the frames by ending the session as soon as all changes to session variables are done.

See: session_write_close()
Access: public
