No, you can not extend two or more classes but you can implement more than one interface in php. Like below

<?php

    class SomeClass extends HelloDolly implements HelloInterface, DollyInterface {
        // do your stuff
    }

You can extend only one parent in your class. From PHP Doc:

A class can inherit the methods and properties of another class by using the keyword extends in the class declaration. It is not possible to extend multiple classes; a class can only inherit from one base class.

But you can use for example many interfaces or traits in one class definition. From PHP Doc:

Classes may implement more than one interface if desired by separating each interface with a comma.
