Interested in an example of polymorphism, with code.

Try to write more detailed questions. To get an answer, explain what exactly you see the problem, how to reproduce it, what you want to get as a result, etc. Give an example that clearly demonstrates the problem. If the question can be reformulated according to the rules set out in the certificate , edit it .

    abstract class Abastact { public function do(); } class Class1 extends Abastact { public function do() { echo 'class1'; } } class Class2 extends Abastact { public function do() { echo 'class2'; } }

    The meaning of polymorphism is that, no matter what object you get ( Class1 or Class2 ), it will definitely have an interface of the Abastact class. This behavior is useful when the object is obtained dynamically.
