Doing that works just fine with a simple example for me. Try
error_reporting (E_ALL) and make sure the config file gets found, etc.

I generally use th following to define globals, nfi if it is really a
correct way to do it tho.

define("glb_MY_ GLOBAL", "myglobalvalue" );

Access is the same as you have by doing:

global glb_MY_GLOBAL;
echo glb_MY_GLOBAL;

You don't have to globalize constants. They are already accessible
globally.

Here it doesn't... but I must admit, it's in a class (db_administrat or)
of wich instances are used in another class (visitor), and there ara
quite a few include statements involved.

Indeed, this seems to work better. Good thing that their values don't
have to change. ;-)

Thanx both for your replies.

Maybe just another question: I used an instance of Visitor to store in a
_SESSION var, so _before_ I call session_start() , I'm obliged to include
the class-definition of Visitor. But when I do this, I get an error
Warning: session_start() : Cannot send session cookie - headers already
sent by (output started at XXX/dbadmin.class.p hp:80) in XXX/register.php
on line 4

Now, dbadmin.class.p hp is ofcourse the class definition wich is called
upon by visitor.class.p hp, but No where in the file I can find anything
that would have 'sent headers', no output at all is used in that class,
only calls to the database. The include to visitor.class.p hp is on line
3 and start_session() on line 4 in register.php. Beneath is included the
code of dbadmin.class.p hp, anyone of you know why this file would have
sent headers before any instances of it are used? I have commented the
"or die" statements that maybe could cause any output, but that won't
help.

What's on this line? If it's not something you expect output from, stick a @
in front of it, but it's likely it's doing something, possibly a header
output of its own.

Well, I left out a commented part, but apart from that, everything is in
the previous post. The line refers to the last line of my class, "}". So
it's not doing anything at all. And as you can see (code in previous
message), there's not any output at all. Weird, no?

Ok, looks like I found it: when using an include, the included page,
shouldn't have <?php and ?> tags. The opening php tag will be ignored,
because php is already opened, but the closing one will be used
therefore terminating the php-code, even if it isn't supposed to do so.
Stupid, when you don't know this. I thought all code had to be captured
between these php-tags.

It *must* have <?php and ?> tags if it is going to be interpreted

PHP "closes" right after the include() and before opening the included
file. If the included file has PHP inside it must be delimited by the
php tags.

It has to be. You're doing some other thing wrong.

He's right, wEEdpEckEr. All my code is built this way, something else is
amiss. Try to reproduce the problem in two smaller files, and post them here
if it still fails s so we can try ourselves?

Hmmm, ok, so I left out the closing tags, and that seemed to work, now
I've put them back, and again it seems to work fine. So it must've been
something completely different, that I've changed and solved without
knowing... Weird. ;-)

Btw: while I'm buggin you guys: getting the screen resolution is not
possible in php I guess? I've been searching the web, and I only can
seem to find references to javascripts...

PHP = Server Side
Screen Res = Client side.

So no, it's not possible. Besides, screen resolution is a red herring
as it makes no allowance for /window/ size.

Well, that's your explaination :p Browsername and OS are also client
side and those can be easily checken within php. ;-)

No, but it 's handy to know, weather most of your visitors are still in
800*600 or have advanced to 1024*768. This is pure for stats, not to
change the outcome of the page.

[ snip ]

Browser name is sent by the client to the server hence PHP can detect this
value. The OS is often derived from this very same value also.

Check the user agent string in your logs.. normally, they'll contain the
browser and the OS the browser is running on.. neither of which are
actually _detected_ client side =)

Yes, I know, I wrote the regex's myself, but it could be that this is also
being send by the browser. Just like the referer-string, or something. This
is also not "detected", so it could have been possible that the resolution
was available too. Helas, it isn't... Too bad, since I can't use javascript
in my model.
