How does the use of parent:: in PHP methods impact inheritance and method overriding?

When using parent:: in PHP methods, it allows the child class to call the overridden method from the parent class. This can be useful when you want to extend the functionality of the parent method in the child class without completely replacing it. By using parent::, you can ensure that the parent method is still executed along with any additional functionality you add in the child class. 

class ParentClass {
    public function someMethod() {
        echo "Parent method";
    }
}

class ChildClass extends ParentClass {
    public function someMethod() {
        parent::someMethod();
        echo " - Child method";
    }
}

$child = new ChildClass();
$child->someMethod(); // Output: Parent method - Child method
