Haskell is a statically typed, functional programming language that excels in concurrency and performance, making it ideal for complex mathematical computations and compiler design. In contrast, PHP is a dynamically typed language primarily used for web development, boasting a vast ecosystem of frameworks and libraries, making it easier for beginners and more suitable for rapid application development.
