Sending post data from a script

Hi All, I'm trying to setup a PHP script that will send a POST data request to a web form. The script needs to be automatic and not driven by a web form. For example. I have a cron script that runs every 15 minutes. The cron script calls my php script on the server and sends the important data to a web based form without human interaction. The data has to be passed with the method="post". Sending the data via a URL request does not suffice. So my question in general is: How can I send HTTP POST data to a remote interface without using an HTML FORM?. Any suggestions would be appreciated.
