Static analysis tools like PHPStan and Psalm can find bugs in PHP code within seconds by analyzing code without executing it. PHPStan performs static analysis to catch errors in code syntax and functionality. It has different configuration levels and plugins. Psalm is also a PHP static analysis tool that can lint code and accommodate grandfathered old code while also incorporating new features. Both tools can help developers find bugs quickly.
