Hello everyone,
I have a question about variable scope that I probably should know the
answer to but it is a puzzle at the moment.
I have a packaged script that I work on that has this problem but I can
simplify the question with an example.
I have a scipt routine that collects a user IP address from
$_SERVER['REMOTE_ADDR']. If I have $ip = $_SERVER['REMOTE_ADDR'];
defined in the script, no problem but if I put the definition in an
include statement like "require_once" it has no value but if I put the
definition in a function in the include file and call the function, it
contains the user IP address. By the way, the mod I am doing is for
tracking badguys activity on a client site so I can see what parts of
the script they are trying to access. I am collecting a lot more than
just the ip address but this is a simplified example.
In the case I am working on, the definitions are in a header file and
the IP collector is at the top of all the pages of the script. I have
other "hardcoded" values defined in the header file that work?
Any ideas on what my problem is? I have created a function in the header
file as a work around but I am wondering why the simple definition does
not get parsed or why some variables work and others do not?
If the answer is obvious and I just don't get it, I hope someone can
enlighten me. Thanks in advance.
