PHP code to post data to another (PHP) script..

Hi everyone I once had a small piece of code which allowed me to pass data to another (PHP) script using the 'POST' method... I would like to make a small script which will allow me to automatically pass data to a page which you should normally have pass by filling in a Form.. With 'GET' this is no problem, but I can't seem to remember how this was done when you should pass it using the POST method.. Does anyone have a small piece of code.. Thanks very much.. Bye Bye David
