How to Inherit base class by super class in PHP ?
To inherit a base class by super class in PHP, you use the extends keyword. For example, the following code shows how to inherit the Animal class by the Dog class:
PHP
class Animal {
protected $name;
public function __construct($name) {
$this-name = $name;
}
public function getName() {
return $this-name;
}
}
class Dog extends Animal {
public function bark() {
echo Woof!;
}
}

The Dog class now inherits all of the properties and methods of the Animal class. This means that a Dog object can access the name property and call the getName() method of the Animal class.
In addition, the Dog class can also override any of the properties and methods of the Animal class. For example, the following code shows how to override the getName() method of the Animal class to return a different value:
PHP
class Dog extends Animal {
public function getName() {
return My dogand#39;s name is . $this-name;
}
}

Now, when a Dog object calls the getName() method, it will return the string My dogand#39;s name is followed by the name of the dog.
Inheritance is a powerful feature of PHP that allows you to reuse code and create more complex and specialized classes.
