PHP and Unit Testing: PHPUnit

Unit testing in PHP involves testing individual units of code to ensure proper functionality. Tests are automated and written by developers, following the test-driven development (TDD) approach. Benefits include bug detection, code quality improvement, refactoring confidence, and documentation. Unit tests should be isolated and not rely on external systems for reliability and maintainability.

PHP and API Security

API security is important in web development to ensure the secure exchange of data between systems. It revolves around confidentiality, integrity, and availability. Developers can implement security measures like authentication, data encryption, and input validation using PHP’s built-in functions and libraries. For example, hash functions can be used to create a unique fingerprint of data for integrity checking, and functions like filter_var() can be used for input validation. By understanding API security principles and utilizing PHP tools, developers can create secure APIs that protect against threats.
