***BOGO*** [PHP] Sending POST variables without html code

["R B" <rbpphp@xxxxxxxxx>]

Hi,

I need to create a cron job PHP script to access every day the information
of a webpage that is out of my server. This webpage needs POST variables to
display the information.

How can i send this POST variables from my PHP script without having a html
form, and receive the required information?

Thanks,

RB
