Module development and code questions

Hello,
I have a serious problem :)
I am creating a new module mymodule.module. I have one function that seems to be a hook but it's not a real one. I have called
it :

	function mymodule_myfunction() {
		return "Thanks Drupal!";
	}

I have added mymodule. Now I have created a new "PHP code" node. I would like to invoke this function from the node so I want to write something like below in the body of the node :

I know that with the drupal API you can have external programs publish posts to your site. Is there a program that takes each RSS post, and posts it into your drupal site. For instance, Feedburner republishes RSS as html, can I get each individual RSS post as a new post in my Drupal Site

I've searched for a solution, but come up empty. I'm concerned about a Google penalty for duplicate content because of the Printer Friendly pages the Print module generates. Is there a simple way to hack the 4.6 version to include a 'nofollow' tag in the URL? I gather this has been done for 4.7. Alternately, will the 4.7 version work on a 4.6 install?

Thanks a million!

Here the error:

Fatal error: Cannot uses string offset have year array in/home/valerie/public_html/drupal4/modules/system.module one line 734.

With this code:

Is there anyone working on this kind of forum function?
I'm just curious.. (Sorry if I'm posting this in the wrong section)

Best regards
