global session variable (possible)

[r4nd0mch4r]

Hello... I have been given this site to fix a few things and it's a bit of a mess... it's like this:

There is the main file, index.php, where I start a session and define a variable with

$_SESSION['var']="something";

Then there are subdirectories, that have their index.php files, the difference is that they don't have the variable 'var' defined in a session.

Now the problem is that if a user starts browsing a site NOT from main index.php but from a subdirectory, the index.php in that subdirectory doesn't have the $_SESSION['var'] defined. That's a problem.

Now, is there a way to define this variable 'var' "globally" or should I so so that all the index.php pages in the site will know the value of it... without user having to first visit the main INDEX.php??

without knowing what you are really trying to accomplish, you can do it the way you suggested, or you could redirect users from the subdirs to the index page to set the variable and then check to see if they can from a different page than the highest up index page, if they came from another, redirect them back to their original request

you can create a prepend.php file that executes all the code you want global then tell your web server to prepend that file to every php file.
