An important lesson I learned.

hey!
I'm called Gikundiro I'm going to tell you An important lesson I learned.
An important lesson I learned is Integrated database with php.
Integrated database with php it is to connect database and hph, it helps to insert data into database by using browser and it help us to display data in browser.
When I was in high school, I liked database and I was good at, when I was in national examination practice I did my project and it run very well but CSS I used it doesn't attractive, panel came to verify my project and he gave many marks because my project it run very well and he told me CSS it is not better than database design and php because my project is management system.
that is reason why I say integrated database with php is An important lesson I learned.
Thank you!!!
