Backend development with PHP and MySQL involves creating the server-side logic that processes requests, interacts with databases, and sends responses to clients. PHP, a widely used open-source scripting language, powers dynamic content generation and server-side operations, while MySQL, a robust relational database, stores structured data in tables. This stack enables developers to build secure, scalable, and data-driven applications by designing APIs, handling form submissions, performing CRUD operations, and implementing authentication systems. Using PHP’s integration with MySQL, developers ensure efficient data management, fast query execution, and strong security measures. Together, PHP and MySQL form a reliable and time-tested foundation for web applications that handle real-world business needs effectively.
