what is inheritance in php?

Question:

what is inheritance in php give me an example?

Answer:

Inheritance permits the implementation of additional functionality in similar objects without the need to reimplement all of the shared functionality.

To inherit an another class we have to use extends Keyword

Example:

class phpInterview{

public fuction result(){

echo 'got selected';

}

}

//extending the above class

class questions extends phpInterview{

public function askedQuestions{

echo 'questions mostly from allphpinterviewquestions.blogspot.com ';

}

}

$obj=new questions();

echo $obj-> askedQuestions();

echo $obj->result();

The output is

questions mostly from allphpinterviewquestions.blogspot.com got selected
