Will upgrading to PHP 5 break anything on WordPress 2.2?
It shouldn’t, but it depends on how heavily you’ve customized PHP. As always, backup everything before you upgrade PHP and if you have your own server, it would be wise to take a backup snapshot before you upgrade as well.
No customizations, just plugins. Its a straight WP install.
On the WP side, you won’t have problems.
If you’re just upgraded a stock PHP without many customizations, you’ll be fine, just backup everything first.
