Access Static properties using PHP object

Question

This is with reference to Get a static property of an instance, I am a newbie and have the following code :

class Foo
{
   public static $my_static = 1;
}

class         


        

Answer 1

Static properties may be accessed on various ways.

Class::$aStaticProp; //by class name

$classname::$aStaticProp; // As of PHP 5.3.0 by object instance

Static properties cannot be accessed through the object using the arrow operator ->.

As of PHP 5.3.0, it's possible to reference the class using a variable. The variable's value can not be a keyword (e.g. self, parent and static).

More you can read in manual

Answer 2

within the class you have to use like self::$staticPropery if the function accessing to the variable is also static.

Answer 3

$instance::$staticProperty is simply a convenience shorthand for Class::$staticProperty. Since you already have an instance of a class and the syntax is unambiguous, PHP saves you from writing a potentially long class name. There's no functional difference.
