What confuses me at this point still is where to save PHP and MySQL. Let me clarify.
*I create an HTML5 page save it as index,html with a link in the gead section pointing to where I save the CSS file below
*I create a CSS3 page and save it as something like main.css in a separate file in the same folder as the html
This is where I get lost
* I create a PHP page and save it in the same folder as the above two with a PHP extension and point to it in the HTML head?
* I create a database which I'm working on the course, but the PHP will point to the database from the PHP page?
I really appreciate the time to help me get through the basics. Only so much you can learn from watching videos if you start from the wrong direction.
