All I need is,how to send GPS data to my phpmyadmin sql database
phpMyAdmin is a PHP script that administers MySQL databases. It is NOT the database system.
You need some other php script that the Arduino can make a GET request to, supplying the necessary data.
I need arduino code for it
Not until you have the PHP script written and tested. When you do, you’ll have a much better idea that the GET request needs to look like.
All of the standard GSM libraries know how to make a GET request.
I need location names not latitude and longitudes.
The GPS does NOT know the location name. For a commercial GPS device, the GPS chip provides the latitude and longitude values, and the microcontroller maps them to locations on a map and possibly to place names.
