vBulletin 4.2.2 under PHP 4.5.5 - Is it OK?

[Rik Brown]

We are currently running VB 4.2.2 under PHP 5.3.3.

Per the VB 4.2.2 release announcement, there are numerous fixes to that release for PHP 5.4 compatibility.

For reasons totally unrelated to VB, we may need to upgrade our server to from PHP 5.3.3 to PHP 5.4.4.

Would PHP 5.4.4 cause any problems for VB 4.2.2?

Thanks. -- Rik

PS: I would assume not but I've gotten into trouble in the past with such assumptions.

Definitely dump PHP 5.3.3 as that has a nasty exploit in it, unless your server has been patched correctly. Any of the more recent 5.3 versions are fine. PHP v5.3.3 was used on many servers as it worked well with most of the accelerators out there, that is why the host companies tried to stay with it.

You should search the last four weeks (vbulletin.org and vbulletin.com) about PHP v5.4+, you will get a good feel about the pros and cons.

This won't help you, but it will give you one more viewpoint:
We run are own servers: in production we use php5.3 series on development we run v5.3 and v5.4. We still run vbulletin v4.2.0 in production, but we have taken the critical patches from v4.2.1 and v4.2.2.
