PHP is its own programming language that generates HTML pages. The benefit of "pre-processing" HTML pages is that different pages of your website can be customized based on user input (like forms and comments). This is a really cool benefit, but it comes with a learning curve. Most hosting companies already have PHP built in. That means you can upload a PHP page to your website and it will just work. You can find online tutorials if you want to learn PHP, but if you'd rather not learn, you can stick regular HTML into a .php file and it will still work exactly as you'd expect.
Hello Vivy, If you are a beginner and don't want to climb a steep curve to learn the technicalities of managing a hosting company, then consider taking a look at drag & drop website builders. These website builders manage all the hosting and technical aspects of operating a website for you. And, their platform allow you to drag and drop your content when making your pages so you don't have to know how to code. I'd suggest testing out Wix and Weebly to start. Both are code free and have free plans for you to test. They don't have a time limit on their free plans so don't worry about upgrading until you are satisfied with them. But if you really want to use a hosting company (for instance, you want to use WordPress.org), then someone like Bluehost is pretty good, in general. Thanks, Jeremy
This is a massive plus of website builders compared to web developers. A web developer can cost between $300 and $1,000 for template customization alone, and a fully customized website built from scratch will often amount to thousands. Making your own website using a builder, meanwhile, allows you to get a fully functioning website up and running for less than the price of a coffee.
