i have noticed wordpress plugin classes pass class method hook using ampersand prefix.
for example:
add_action( 'somehook', array( &$this, 'some_function' ) ); is there specific reason so?
i understand & makes pass reference instead of instance of time see used seems irrelevant method , not object.
is there particular reason way wordpress action hooks?
it's fallback php4 objects passed values.
since wordpress requires php5.2.4 @ least, there're no reasons use & prefix anymore.
