Video Runtime: 07:33
Let’s talk about why and how does WordPress use PHP. Why does it use it? Because it’s a solid programming language for web development. It’s very popular and prevalent and powers the majority of websites.
WordPress uses PHP to do all of its processing including figuring out what the URL’s web request is, what to go grab from the database, what files to load and when, validating user permissions, checking options, fetching post metadata, calling plugins, and calling the theme. It uses it to process form fields, image and document uploads, and so much more.
It uses it to build the web page and each of its components including inserting of the dynamic content from the database. For both the back end and front end, WordPress uses PHP to build the web page and interface. It calls the HTML views and then embeds the specified content into it.
It uses PHP to render the web page out to the browser.
If you listen carefully, you can hear the 1s and 0s flowing in your computer.
