PHP and Querystring

[dtshedd@yahoo.com]

I am trying to automate searches on a web site which uses a php script.
After examining the HTML form, I assumed I could assemble a
querystring and submit something like

http://mysite.com/myscript.php?name1=value1&name2=value2

however I receive basically a blank page back. There is nothing other
than the address for the php script in the address bar of the browser.

I am a novice programmer, and have no background in php. was hoping
someone could steer me in the direction of some useful
resources/examples.
