Now why would you do

the '&' doesn't make sense here. The code above still wouldn't make it make sense. count() doesn't modify, NO SENSE in using it there.
Not about modify but about speed Giving count a pointer to a large var should be faster then giving count the large value of the var Wico PHP has no notion of a pointer, therefore it's not worth using &$data here.

If using references in php are not worth using them why the hell are they introduced then? Wico
