Month: 2025-09 - Summary of work on phpstan/phpstan-src: Key features delivered - Closure $this context type inference in function and method calls: Enhanced PHPStan’s type analysis to correctly infer the $this context inside closures passed as arguments to functions, methods, or static methods. Added new interfaces and provider classes and integrated them into the analysis scope resolution. Commits: 70a039f674766b1cd47b23215db32fcb2e170b55; 207639fc7821afb94e06af82a68d825556980384. - Static analysis: improved handling of dynamic properties across inheritance: Refactored logic for allowing dynamic properties in PHP classes, ensuring __get, __set, and __isset are handled correctly on final classes and that the "AllowDynamicProperties" attribute is evaluated consistently across class hierarchies, improving accuracy of static analysis. Commit: 207639fc7821afb94e06af82a68d825556980384. Major bugs fixed - ObjectShape optional properties are checked correctly: Fix to continue processing when a property in an ObjectShape is missing, rather than returning an error. Introduces test bug-13511.php to validate handling of optional properties in object shapes. Commit: 330ca960d9ea0ac458c061823a99749809089d75. Overall impact and accomplishments - Improved type inference accuracy for closures and more reliable dynamic property handling, reducing false positives and enabling safer refactors for PHP projects. Strengthened cross-inheritance analysis and final-class semantics, leading to more consistent static checks. Augmented test coverage with regression tests to guard object-shape optional properties behavior. Technologies/skills demonstrated - PHP internals and static analysis scope resolution, interface/provider architecture for analysis extensions, handling of magic methods and dynamic properties, and test-driven development with regression tests. Business value - More reliable type analysis reduces debugging time for developers, accelerates safe refactors, and supports more aggressive static checks in CI pipelines, improving code quality and maintainability across PHPStan consumers from our ecosystem.
