The frontend of a typical web application deals with the design aspect. HTML, JavaScript and CSS technologies are mainly used as the frontend tools. PHP on the other hand is a server-side programming language. It is used to prepare algorithms for handling the processing logic, interacting with the databases, and handling the security aspects. Hence, it can be said that PHP is primarily used for backend development.

The amount of time it takes to learn PHP varies from person to person. To learn PHP Basics it may take 1-2 months. To get Intermediate Skills, and additional period of 2-3 months may be needed to mater the OOP concepts, and PHP frameworks, and building more complex projects.
