method is the function in the class, many times we can not tell the difference between the method and the function, in the process-oriented program design is called functions, in object-oriented function is called a method.

Like properties, the methods of the class also have public,protected and private access control.

The keyword for access control represents the meaning:
Public: Publicly available
Protected: Protected
Private: Private

We can define methods like this:

Class Car {public    function GetName () {        return ' car ';    }?} $car = new car (); Echo $car->getname ();

Statically decorated with keywords, called static methods, static methods do not need to instantiate objects, can be called directly through the class name, the operator is a double colon:.

Class Car {public    static function GetName () {        return ' car ';    }?} Echo Car::getname (); The result is "car"
