Just completed SQL course. What's next?

Question

I don't know if it happens the same to you but, compared to other courses, SQL one was too easy. I feel that if I really want to say "I know SQL" I must learn something that's deeper than this course. What do you reccomend?

Answer 1

Build something with XAMPP

Answer 2

I would learn PHP because you can couple the two together to create forums, login systems etc.
If you need more knowledge of SQL and how to couple i with PHP, use
w3schools for SQL
php7 manual for PHP and how to couple it with SQL using databases.
