I assume you have already read the php manual about sessions?

Anon

I've read the manual, but there isn't much that could help me except custom session handlers. I was hoping for a cheap cheat.

Unless i've missed something that you are maybe going to point out.

Argh

Well, what exactly do you want to do besides starting an stopping a session?

Anon

I explained it badly so here is a piece from the manual(ASP):

5.2.2 Global.asa File

Global.asa is an optional file that stores script procedures and objects used globally by an application. Script procedures declared in Global.asa can only be for Application_OnStart Event, Application_OnEnd Event, Session_OnStart Event, and Session_OnEnd Event events. Scripts that do not have session or application scope cause the server to return an error. Global.asa files that do not use Application Events or Session Events are ignored. Script procedures declared in Global.asa cannot be called from ASP pages in an application.

The file must be called Global.asa and stored in the root directory of the application. There can only be one Global.asa file per application.

5.2.4.1 Session_OnStart Event
The Session_OnStart event occurs when the server creates a new session. The server processes this script prior to executing the requested page. The Session_OnStart event is where you set any session-wide variables, they will be set before any pages are accessed. All the built-in are available and can be referenced in the Session_OnStart event script.

Syntax

Sub Session_OnStart

. . .

End Sub

</SCRIPT>

Parameters

ScriptLanguage
Specifies the scripting language used to write the event script. It may be any supported scripting language, such as VBScript or JScript. If more than one event uses the same scripting language, they can be combined under a single set of <SCRIPT> tags.
Runat
Must be "Server".

5.2.4.2 Session_OnEnd Event
The Session_OnEnd event occurs when a session is abandoned or times out. Only the Application, Server and Session built-in objects are available.

Syntax

Sub Session_OnEnd

. . .

End Sub

</SCRIPT>

Parameters

I'm looking for the equilvilent of
5.2.4.1 Session_OnStart Event AND
5.2.4.2 Session_OnEnd Event is PHP.

Hope this helps.

PHP works differently.

ASP sessions are not the same as PHP sessions. PHP doesn't have 'applications', just seperate scripts.

In PHP, a 'session' is just a method of storing variables and object-data so it can be re-used later, in any script, as long as you know the session's ID.

If you need as set of functions in all the scripts that you use for an application, then each script must use include() or require() to load those functions from a library.

there is not Session_OnEnd in PHP. This is perhaps the only thing 'missing' from PHP's session handling. On the other hand, HTTP is stateless, so there is nothing left to do when a session times out anyway.

When a session times out in PHP, it is simply detroyed; all the data for that session is erased from disk. YOu can't define a script or function that should be executed when the session times out.

The only way to get that kind of functionality is by making it yourself.
Store the session data somewhere else, like in a database. At every pageview, update the 'last accessed' datetime for that session. Then use a crontab script to periodically check the database to see if the session has timed out. If it has, run a PHP script to cleanup that session.
