How to send commands to gps tracker with php

Question

I'm trying to develop php based tracking software for my gps tracker gps107.

My tracker has GPRS and I have successfully associated my tracker with open source tracking software "Traccar" which is written in java and located in my server.

But now I want to develop my own custom software for my needs in php.

I also have the protocol manual where I can see available commands and their responses.

example command for locating:

server -> device

**,imei:359586018966098,100

device -> server imei:353451044508750,001,0809231929,,F,055403.000,A,2233.1870,N,11354.3067,E,0.00,,;

How can I send these commands with php ?

Although I'm not positive, I believe you want to send using UDP — Erik Flitman

That may be the case because the tracker supports tcp and udp. — MulOnPomm

The communication between server and a device is made with UDP or TCP protocol. To make this type of a connection with PHP you have to create PHP socket server. Then you assign server IP and port to your device, and the device will connect to the server as a client. After that you can receive and send commands.
