What is the difference between calling methods from other classes in static methods in PHP?

When calling methods from other classes in static methods in PHP, you need to use the scope resolution operator (::) to access the method. This is because static methods are called on the class itself rather than an instance of the class. Make sure to include the class name before the method name when calling it within a static method.

class MyClass {
    public static function myStaticMethod() {
        // Call a method from another class
        OtherClass::otherMethod();
    }
}

class OtherClass {
    public static function otherMethod() {
        echo "This is a method from OtherClass";
    }
}

MyClass::myStaticMethod(); // Output: This is a method from OtherClass
