Hi, can I build an Iphone app, that will link to a website made from PHP that has a mySQL databse. The user signups or logins and retrives data from mySQL, actual apps is made from PHP, like a website but it is an apps. Do you know what I mean? I know that iphone sdk has its own language, but its too complicated, nothing likePHP or C#. can I do this? any links?
You can access and retrieve anything from the web-- however you cannot develop applications using php for iphones. Q..
iOS development may not be quite as difficult as you think. Once registered, you have access to a wealth of tutorials and videos. If you are proficient with PHP & c# you surely can develop a simple app for retreiving data. (And to answer your question, no PHP is not an iOS development platform.)
I don't know if they allow it in the appstore, but it's perfectly possible if you make a web app. You'd make an app that loads up a browser (without any gui) and automatically goes to a website containing your webapp. I used php to make a highscoretable once, I also used that non-gui browser to show the highscores, so why not?
As far as I am concerned it can't be done using PHP. Further you can make yourself sure consulting with iphone developers.
