$this can only be used within the class though, and never outside.
Also, there are static variables and functions, and to refer to them you must use the self:: method.

PHP Code:


			
class staticClass {
public static $szVariable;

public static function setVar($szVar) {
self::$szVariable = $szVar;
}

}

The good thing about this is that you don't have to create the object.

PHP Code:


			
include('staticClass.php');

staticClass::setVar('Hi there!');
echo staticClass::$szVariable;

Output:

Code:

Hi there!

I use this method in my DB factory, and it's awesome!
