The guide covers pseudo-types for strings (non-empty-string, literal-string), numbers (positive-int, int), arrays (list, array shapes), object shapes, generics with @template, conditional types, and type assertions. It demonstrates how to define precise contracts beyond native PHP types, prevent runtime errors through compile-time checks, and manage false positives using baselines and targeted suppressions. ## Full article daily.dev links to this article rather than hosting it.
