PHP (Hypertext Preprocessor) is a web-based programming language that has te ability to process data dynamically. In principle, the server will work if there is a request from a client. PHP can be said to be a server-side embedded scripting language, it can do the following:

1. Read request with PHP script from the browser
2. Search page on the server
3. Processing through the instructions provided by PHP to modify page
4. Send back the page to the client via the internet which is the process of echo / printf

Later he released PHP version 2.0 which has had the ability to access the database and integrates with HTML.
