Multiple users processing the same form
I am new to html and php.. I am a bit intrigued on how php handles forms.. what happens when two or more users submit a form in the exact same time, how does php handles this, is there any way that data could be mingled between them, or how is this avoided?

To elaborate a little on Aarons answer when you submit a form that data goes into a request. That request is sent to the server using a method such as post or get. The the server proccess the data and executes whatever it is programmed to do. Each request is seperate so data is not mingled.
It is like a group of phone lines. Simply picking up the phone doesnt connect you with everyone else who is on the phone. The call is proccessed by the central unit (the server for us) which makes the connection based on what number you dialed.
Hope that helps!

When you submit your form to the server, the request is handled in its own process. This prevents data from getting mingled.
