Shifting to PHP5
Ryan Boren has already touched on the topic of WordPress and PHP5. For those who are not yet aware, PHP has announced that the popular PHP4 is to be phased out over the next year and PHP5 is now the top boy.
Most popular open source application including WordPress have not yet officially adopted PHP5. This is creating somewhat of a catch-22 situation; what is the point of migrating to PHP5 if nothing works!
Its a challenge that BlogSec has to face as well. Our new WordPress hardening project is designed for PHP5 with some debate amongst the team members whether a version for PHP4 is worth it . . .
I would check out the rest of Ryan’s post, he makes some great points.

I’ve just updated my own PHP install to PHP5(took time and alot of nerves…). I have to say that I didn’t encounter any problems with WP or anything else(except for some warnings I got about open_basedir restrictions).
As much as I know no functions where dropped (http://www.php.net/manual/en/faq.migration5.php & http://www.php.net/manual/en/migration5.incompatible.php). And many covered incompatible changes can be avoided by good programming style, so porting from PHP 4 to 5 shouldn’t be a big problem.
So the number of PHP5 Servers will increase, once that number is high enough the developer can drop the developing process of PHP4 and move on to PHP5. There are alot of benefits to PHP5!
Pedro, thanks, fixed :)
Phil, great input, I think PHP5 may be alot better now, but I think alot of people still have the stigma of instability that accompanied earlier versions.
Looks like the link to Ryan’s post is broken. :)
