Right
<?
class A{
public static $a = 'Hello';
public $b ='World';
public function __construct()
{
$this->b = 'Hello World';
}
public function NonStatic()
{
print "\nHere value of b is: ".$this->b;
//Static members can be accessed though within object methods
print "\nA value is: ".self::$a;
}
public static function StaticMethod()
{
print "\n A value is: ".self::$a;
//This will not work, cannot access object variables(members) within
Static methods
//print "\n B value is : ".$this->b;
}
} //end class
$obj1 = new A();
A::StaticMethod();
$obj1->NotStatic();
?>
