Typo3: read URL parameter and display in template?

I bet it is very simle but I am just too dumb. I have the following code in Typo3 template:
 file = fileadmin/smo_latesttopics_export.php

The URL will have a parameter named "act".

3 questions:
1) How should the code look like that I display the value of the paramater at the marker "IMPORTED-MENU"?
2) What is the code that the parameter will be used "as is" when calling the include?
3) Is it possible to use a variable in typoScript that can be used from the PH include too? (to avoid calling the include wiht a parameter in the URL)?

First - I am not sure "-" is allowed as a part of TS object name, however I may be wrong.

1. <? echo t3lib_div::_GET('act'); ?>

You can also go for the GET/POST variables directly, however if you use RealURL or some other extensions your scripts will be broken. This is why you need to go through the standard TYPO3 API - see http://typo3.org/documentation/document-library/core-documentation/doc_core_api/4.1.0/view/3/2/#id3526172 for details

2. Not sure I understand the question. The code configured as "PHP_SCRIPT_EXT" is called using include() from the core, so all global variables available at that moment are available to it too. There are no parameters passed to it since it's not a function - there are only parameters passed to the whole PHP application and stored in the global vars.

3. There are several ways to do it. What is the nature of informaiton that you are trying to pass to your script? Depending on whether it is page-specific, template specific or otherways there could be options.
