google maps server php not working

[maryammagdy]

Hello, I'm trying to design a google maps server for online tracking. It accepts variables sent by a gsm module. so far I can see a googlemaps with an initial position but it doesn't seem to receive the parameters I send it using the gsm module. I use a serial terminal to send AT commands to the server. The gsm module connects successfully to the internet and can open websites and even the server's webpage but when I let it send the longitude and latitude it sends me an error.
For example this AT command which opens the server webpage works:
AT#HTTPCFG=0,"http://localhost/demo_sim908.php"

But this one which sends the parameters gives me an error:
AT#HTTPCFG=0,"http://localhost/demo_sim908.php?visor=false&latitude=0&longitude=0&altitude=0&time=0&satellites=0&speedOTG=0&course=0"

The server code is taken from here https://www.cooking-hacks.com/projects/arduino-realtime-gps-gprs-vehicle-tracking
