Macros dynamically add methods to Laravel's macroable classes—Request, Response, Collection, Query Builder, and more. I define macros in service providers' boot() methods. The macro() method accepts a name and closure. Macros access $this context like regular methods. Mixin provides multiple macros at once from a class. I use macros for project-specific helpers without extending classes. String, Arr, and Collection macros create domain-specific utilities. Request macros add custom validation or data extraction. This extensibility keeps framework modifications organized and upgradeable. Macros demonstrate Laravel's flexibility for customization.
