I'm always pimping Xdebug, so just remember it will show you where > your real bottlenecks are instead of guessing. *shrug* xdebug is da bomb; thats what i used to build the charts from the performance report ;) ok, so heres what im thinking. any functions that return by reference can safely be changed, right? so i could do a mass replace like this find: 'function &' replace: 'function ' note, there is a space after function in the replace. i think the only reason to use return by reference is when returning an object to avoid getting a copy back in the php4 days. the rest im thinking can be done by hand as time goes on. waddya all think? thx, -nathan
