It seems this method has a security level different from the getStaticProperties method.





If you make two classes A and B looking like





<?php


class A{


        protected static $static_var='foo';





        public function getStatic(){


           $class=new ReflectionClass($this);


           return $class->getStaticPropertyValue('static_var');


        }





        public function getStatic2(){


            $class=new ReflectionClass($this);


            $staticProps=$class->getStaticProperties();


            return $staticProps['static_var'];


        }





        public function __construct(){


              echo $this->getStatic2();


              echo $this->getStatic();


        }


}





class B extends A{


        protected static $static_var='foo2';





}


?>





Then the output will be an exception for the getStatic() call, when the getStatic2() will correctly return 'foo2';

If you want to change a static property of a variable class...



PHP 5.2

<?php

$reflection = new ReflectionClass($className);

$staticPropertyReference = & $reflection->getStaticPropertyValue($staticPropertyName);



$staticPropertyReference = 'new value';

?>



PHP 5.3

<?php

$className::$$classProperty

?>
