First of all, this seems to be just plagarism of http://www.making-the-web.com/2007/12/09/unofficial-php-6-ch... from December of 2007, bear this in mind when considering the reputation of tuvinh.com. (Unless of course tuvinh is Brendon, which seems unlikely since Brendon said he'd be updating the list and surely he thought of something in the ensuing 14 months, or perhaps "compiled this list" is construed as "copy and pasted")

Second I think the (original) list is a useful 60 second communication. It lets me know that essentially all existing, non-trivial PHP code will break at PHP6 and need to be fixed.
