Static Analysis for PHP: Automated Bug Detection and Code Quality

Writing PHP code that is both highly reliable and easy to maintain requires more than just manual testing. Static analysis allows you to scan your codebase automatically to detect hidden bugs, enforce strict type safety, and maintain clean standards without executing a single line of code. This course guides you through integrating modern static analysis tools into your development workflow to write professional-grade PHP. You will transition from relying on manual debugging to confidently deploying robust applications backed by automated code verification. By understanding how static analyzers evaluate your logic, you will write cleaner code and catch edge-case bugs early in the development lifecycle. What you'll learn: - Understand the core principles of static analysis and how it prevents production bugs - Configure and run PHPStan to analyze your codebase at varying levels of strictness - Enforce modern PHP type hints, return types, and strict typing rules for safer code - Identify and resolve complex type mismatches, dead code, and unhandled logic paths - Integrate static analysis checks into modern CI/CD automation pipelines - Apply best practices for gradual adoption of static analysis in existing legacy codebases This text-based course starts with the foundational concepts of static analysis and type theory, then moves step-by-step through configuration, error resolution, and automated workflows. You will read clear explanations, analyze code examples, and learn how to interpret analyzer reports effectively. Designed for beginner to intermediate PHP developers, this course requires a basic understanding of PHP syntax but assumes no prior experience with static analysis tools.
