Inserting files in templates

[Anon]

Here's a part of the code in my page, which I'm having trouble with. It works on my PHP-enabled IIS server, but not on my webhost's PHP-enabled Apache server

<?
global $op;
if ($op!="")
include($op.".html");
else
include('news.html');
?>

If I wanted to make a link to the file that makes it include a file (other than news.html) should it be something like:

index.php?op=articles

That's all... please email me with an answer...

1) this is not a personal help forum where we email you privately with the answer.

2) it would help if you said what goes wrong with this code, and what the error messages are (if any)

Ok... the thing that goes wrong is, it doesn't respond to any variables passed through urls (which is it's intended use)

I pass things like:

index.php?op=articles
index.php?$op=articles
index.php?op="articles"
[ with all sorts of values ]
and it only includes news.php... is there something I am missing???
