Arduino/GSM access PHP Script

Hey Everyone!

I'm fairly new to the Arduino world and have basically dived right into it with both feet! lol

I have an Arduino Uno with a GSM Shield working and registered. I would basically need have the Arduino send some data over my PHP Script on my webserver. Would anyone know or done this before? I'm kind of stuck at the point where i can get the GSM registered to the carrier.. but i am not able to contact my server and call up the PHP Script.

Any help would be greatly appreciated!

Thanks in advance, Tony
