What are the PHP reference books? Solutions

What are the PHP reference books?
Please ask what types of books are on the board.
For example, the computer as a server in the form of Yifi can be used to do the receiving of information or exchange of information between the motion
Ditto in 3G mode
Is that these types of [programs] don't know if there's any teaching
Basically, all the books I've read are teaching the basics.
For example, how the form is built ... Computer (server side) and computer (client) between the passing information
I wonder if there's a way to connect with the outside.

For example: The computer (server side) Arduino (3G module) Arduino 3G module can transmit the received GPS information to the servo terminal

What I want is that the above type of computer can connect with something outside the computer and not the computer.

Use whatever network is the same.
