hasMethod('foo')) { echo "Method foo exists in class MyClass"; } ?>
hasMethod('bar')) { echo "Method bar exists in interface MyInterface"; } ?>In this example, the code defines an interface called MyInterface with a single method called bar. The ReflectionClass is then used to check if the interface has a method called bar. If it does, the script outputs a message indicating that the method exists. Package Library: The package library for the PHP ReflectionClass class is the PHP Core Library. This class is a built-in class in PHP and does not require any additional installation or configuration.
