class MyClass { abstract public function myFunction(); } $reflectionMethod = new ReflectionMethod('MyClass', 'myFunction'); if ($reflectionMethod->isAbstract()) { echo "The function is an abstract function."; } else { echo "The function is not an abstract function."; }
interface MyInterface { public function myFunction(); } class MyClass implements MyInterface { public function myFunction() { echo "Hello, world!"; } } $reflectionMethod = new ReflectionMethod('MyClass', 'myFunction'); if ($reflectionMethod->isAbstract()) { echo "The function is an abstract function."; } else { echo "The function is not an abstract function."; }In this example, we define an interface called MyInterface with one method called "myFunction." We then define a class called MyClass that implements this interface and defines the myFunction method. We create a new ReflectionMethod object and pass in the MyClass class and myFunction method as parameters. We use the isAbstract method to check if the method is abstract or not. The ReflectionMethod class is part of the PHP Core Library.
