Is their anydifference between sql and my sql

Answer 1

SQL is the language.
mySQL is one of the "tool" to communicate between PHP and a database by sending SQL requests.

Answer 2

I don't use mySQL so I won't be able to answer you about that. For me I use another one call "PDO". That's a powerful object which include methods to write safe requests.
The idea of PDO is you instanciate a new PDO object,

You setup the connection to access your database,

You open a connection,

You write a request,

PDO prepare the request by safely remplacing variables inside the request with there values,

You trigger the request

PDO return a object with matching result(s)

You close the connection with the database for safety

You handle the result of PDO.

A good way to learn SQL, except by learning with Sololearn, is to use Phpmyadmin on a dummy database to prevent break something.
Then when you click on button inside Phpmyadmin, each time Phpmyadmin is making a SQL request, it will write the SQL request it just use. You can see SQL behavior that way and directly test your own request inside Phpmyadmin to see what happen
