In a blogging website how the codes of a blog-read page work? [closed]

I want to learn the proper way that how the blog title comes as a page.
Like “Be-in-Your-Feminine-Energy-with-a-Man” this is just the title of a blog. But how it comes as a page in the website wikihow.com ?

I want to know how the php works with the database.

Please help.
Thank you.
