OOP -> Static Methods & Properties

Static Methods: Method of a class that can be access by using scope resolution (i.e ::) without create the instance of that class;

Example of Static Methods

class ABC {
    public $name='Arun';
    public static function test() {
      return 'Testing Message';
    }
}
//will print the Testing Message';
echo ABC::test();
$obj = new ABC();
//will print the Testing Message';
echo $obj->test();

Following are the property of static method

• Can be use with scope resolution operator (::)
• Static method delcared with use of "static" keyword.
• Need not to create the object of that class
• Within static function, we can not use other method
• We can use other method in static function, but need to create object to class method
• Calling non-static methods within static function,  generates an E_STRICT level warning.
