How does calling a static method using double colons differ from using the "->" operator in PHP?

When calling a static method using double colons (::), you are accessing the method directly from the class itself without the need to instantiate an object. On the other hand, when using the "->" operator, you are calling the method on an instantiated object of that class. To call a static method using double colons, you simply use the class name followed by the double colons and the method name. For example, MyClass::myStaticMethod(); To call a method using the "->" operator, you need to first create an object of that class and then use the arrow operator to call the method. For example, $obj = new MyClass(); $obj->myMethod();
