Checking variables in an include

[Victor]

Hi everybody,

could anybody explain the following phenomen :

I have this line in my project :

include
"http://".$domain."/help/".$language ."/".$defaultIndex ."/".$help.".p hp";

This construct properly includes the file I need to. And the included
file contains the following line :

echo $domain;

- and on this place comes nothing: obviously, the variable '$domain' is
not set for the <help.php>.

Why ?

Regards

Victor

How are you expecting it to be set? You're (almost certainly) executing the
remote PHP file in a totally different context - all you're include()ing is the
output of the PHP file from the remote server.

The only way it could work is if the webserver you're calling returns the PHP
source verbatim, without processing it, in which case it's run in the same
context as the calling script.

Are you sure you want to be doing remote HTTP includes? Including from the
filesystem is by far the more common usage, and is more likely to behave how
you expect.

You see, the file I am including is not a remote one. It sits in my
project directory. I agree, it might be not the best way to do
includes, but this way it is easier for me, because I use rather many
of them, calling them from different sublevels of the directory. And
the file that makes the described include is also not the one that has
set the variable $domain, but already 4th or something like this in the
hierarchy of includes. Nevertheless, it sees the variable and
constructs a correct name of the next include.
Suddenly, this following include does not see the $domain any more...

So include it through the filesystem. By using an HTTP URL you are doing
something completely different; reading the output of a completely separate
instance of PHP.

Thanks Andy!

I believe you have right... I'll try it and then report the result.
