Each virtual is a totally separate HTTP request, in the stateless HTTP protocol, and your environment variables in one will not (ever) survive to the next. 2. Apache is configured to do virtual requests as some kind of sub-request and it's all in one single HTTP request/process/thread. I *think* this is a feature I've read about in HTTP specification at http://apache.org If I'm right about all this, none of this has much to do with PHP really, and has everything to do with Apache and configuration. You'd have the same issues in mod_perl or mod_python as you are having in PHP.

[PHP] Mixed PHP/SSI and environment variables
Hello, I have a problem with the persistence of environment variables when mixing PHP and SSI (Apache) and I am not sure if I just made an error or if this approach cannot work at all. So please consider the following files: setvar.shtml - !--#set var=myvar value=myval -- - showvar.php - ?php echo apache_getenv( myvar ); ? - info.shtml - !--#include virtual=setvar.shtml -- !--#include virtual=showvar.php -- - info.php - ?php virtual( setvar.shtml ); echo apache_getenv( myvar ); ? - What I would expect is that you get the same result if you call info.shtml and info.php. What happens when I tried (PHP 4.3.10 with both Apache 1.3.33 and 2.0.53): the shtml shows the variable but the php does not, it seems to forget the variable set in setvar.shtml.

that way php will take everything inside the ?php ? tags and

This won't work is your PHP code has comments using /* */ syntax in it
already. I always just through an if(false){ } around huge portions of
mixed content that I want to comment out. Unless you have unbalanced curly
braces in the chunk you want to comment out, it should work.

In asp there is a session timeout function that allows the session to end after the session is INACTIVE for x seconds/minutes ! How do i do this in php ? You can set the lifetime of the session in php.ini. session.gc_maxlifetime is the time after which, inactive sessions will be deleted. session.gc_probability controls the percentage chance that the garbage collection (session deletion) will be triggered with each session_start(). You can also set some of the cookie parameters. All the details are in the manual, give it a try. http://www.php.net/manual/en/ref.session.php Is there a way to open a php page in internet expl. without having a url/adress bar or a back and forward button , if so how do i go to work?

If so how can i stop it ? The session cookie will remain on his computer. It's only good for your site though. If they return, the session will still be active, unless it's been they wait over X minutes and the session file on the server is deleted by the garbage collection. Remember how HTTP works.
