Frequently asked questions

What is the difference between PHP and JavaScript?

PHP traditionally runs on the server and produces the page that gets sent out; JavaScript runs in the visitor's browser and changes the page after it arrives. JavaScript can also run on servers nowadays, but the browser remains its home ground.

Is PHP still used?

Yes. It powers a large share of existing websites, including the content management systems many sites are built on, and it continues to receive new versions and language features.

Do you need PHP to make a website?

No. A site can be plain HTML and CSS with no server-side language at all. PHP becomes relevant when pages need to be assembled from stored data, handle logins or process form submissions on the server.

What is the meaning of PHP?

"PHP" (noun) means a programming language that runs on a web server to build pages before they are sent to the visitor, commonly used for websites that draw their content from a database.
