PHP (Hypertext Preprocessor) is a popular server-side scripting language used for web development. It is designed to create dynamic web pages by interacting with databases and performing server-side tasks. It allows you to write logic that can handle user input, manage sessions, and generate content based on requests.
MySQL is an open-source relational database management system (RDBMS) that stores data in tables and allows you to manage, query, and manipulate that data using SQL (Structured Query Language). It is often used with PHP to store, retrieve, and manage data on websites or applications.
