Please, explain this to me, because I couldn't figure it out by myself... If register_globals is set to 'off', and because it's good practice, you should allways initzialize your variables? So I should write:
$test = $_POST['test']; and then I can use $test as usuall... But what about local variables then? Variables that shouldn't be past from one page to another? And is $_POST[] short for $HTTP_POST_VARS[] or is it something else? And should you use $_SESSION[] and not session_register()?!? Sorry for these simple questions, but I would like to do things right... My knowledge comes basicly just from 'Beginning PHP4 (WROX)' and it seems that the book doesn't dig so deep into this matter...
