Register Globals

[JoJo86]

Hi

I am extremely new to PHP and I am attempting to follow tutorials using the Larry Ullman book (PHP and MySQL for Dynamic Web Sites).

I have only just started these tutorials and I have already got a snag

I need to be able to use $HTTP_USER_AGENT and $REMOTE_ADDR variables but they are not working on my computer. The book suggests changing the configuration of XAMPP to switch on Register Globals. I have searched around the net and found this can be done using the PHP.INI file under XAMPP\Apache\bin\.

However, it has come to my attention that I do not have this file (unless I am very blind!).

I installed this only his morning but I am using Vista so that could be causing the issue. I followed the guidelines of not installing it under ProgramFiles so it is under C:\XAMPP.

If there is another way of being able to use these variables can anyone let me know? Again, I am a complete novice so please reply in layman's terms

Thanks, Jo

Suggesting to enable register_globals is really worse...

The correct way is to use the (since 7 years) correct variables:
$HTTP_USER_AGENT -> $_SERVER['HTTP_USER_AGENT']
$REMOTE_ADDR -> $_SERVER['REMOTE_ADDR']
--> http://de.php.net/manual/en/reserved.variables.php

it has come to my attention that I do not have this file (unless I am very blind!).

With phpinfo() you can see, which "php.ini" your PHP is using.

Thank you very much for this handy piece of code

Does this mean that every time there is a predefined variable I should use $_SERVER instead?

Again, thank you very much

Yes. Or $_GET or $_POST. (if you are dealing with forms)
