My question, following your earlier Vista-like questions, would be: what is eZ System's plan for eZ Publish in relation to PHP6? Will there be another port, or is any more challenging approach taken under consideration? This will be nice to know ;)
As you can read, the differences between PHP 5 and PHP 6 are language-wise far from as big as the one between PHP 4 and PHP 5.
At first sight, the only (necessary) changes for eZ Publish will be:
- remove certain installation checks related to features that have been removed from PHP (safe mode, magic quotes, etc)
- use the PHP 6 unicode features - replace usage of POSIX regex functions (ereg) with Perl Compatible regex functions (preg)
List of files in trunk (4.1.0alpha1) using ereg now:

The question remains - when will PHP4 code become problematic? Around PHP6, PHP7? ;) Hopefully, the components will be introduced soon enough.
