first time user

hi folks, i am somewhat like a new newbie, just read my first php tutorial, installed an apache server on my windows and php on top for testing , first question is : is this the right place for me here to ask questions or is this newsgroup rather for advanced users? second question is my task i want to complete in PHP : i have an array for a dhtml navigation menu for my site. all the links are "hard coded" inside the array and are , of course , the same for the whole site EXCEPT for the language selection. now, for example, i am on a page called about.php, i am clicking on the link for the german version and a page called german/about.php should be retrieved. same for spanish. now, what do i do? i have found a php snippet that reads the current url <?php $filelocation=$HTTP_HOST.$PHP_SELF; echo($filelocation);?> but can i use this somehow and how do i do that? i would be happy for any kind of advice . thankyou cookie
