I need to develop a web app. (PHP) 100% for mobile phones and need to get the information from the mobile phone GPS, in order to get the user's current position. My question is, what should I do?
I know PHP but I'm completely clueless about the GPS part (never worked with them before). All i'm looking is for headsup to see if I can handle the job or just reject it.
I've heard that the W3 geolocation API does a very good job but after testing it i'm not convinced about the accuracy and browser support. I don't want to use Google's gears due to the fact that it must be downloaded first.
