Geeklog Forums

Hi, could someone give me a quick head up in terms of PHP's global variable deal and how geeklog uses them. More specifically i am interested in the $_USER and $_TABLES Superglobals. Just some pointer on where are they declared, and how do they work in say geeklog context.

I find it hard to understand why superglobals have to be redefined inside each function and the above of course.

Thank you very much, a quick note should suffice.

This would be a good question to send to the devtalk mailing list. Why not try there?

It's just a quick curiosity.

Those variables aren't "superglobals" like those introduced in recent version of PHP. They are simply global variables - and as such, they have to be declared global in every function before they can be used.

$_TABLES comes from lib-database.php, $_USER from lib-session.php

bye, Dirk

Thanks that's all i needed

Well, after a minute of digging, _TABLES is defined in lib-security.php and _USER is defined in lib-sessions.php.

As far as "defining them" in each funtion, you don't. You just declare them as globals. Otherwise the function will not see that variable in it's scope (the local versions are undefined). It's just a thing with PHP.
