Object Operator Usage in PHP

PHP's object operators provide versatile ways to interact with objects. Let's explore their distinct applications:

1. Method Invocation and Property Access (->)

The -> operator is employed to invoke methods and access instance properties directly. For example:

$object->method();
echo $object->property;
Copy after login

2. Static Method and Variable Access (::)

The :: operator accesses static methods, static variables, and calls methods in parent classes from child classes. For instance:

Class::staticMethod();
echo Class::STATIC_VARIABLE;
Copy after login

Parent Method Invocation (::)

Within child classes, :: can be used to invoke a method from the parent class:

class ChildClass extends ParentClass {
    public function overriddenMethod() {
        ParentClass::parentMethod();
    }
}
Copy after login
