We need a little bit of help; should only take about 30 seconds.
Last week we started working on ProofBuddy 2.5. When we started 2.0 we looked at dropping support for PHP 4, but decided against it because we were still getting a large enough percentage of users installing on servers with PHP 4 that it didn't seem the right decision.
With ProofBuddy 2.5 we're at that point again. This time around unless there is an overwhelming need for PHP 4 support we're going with PHP 5.2. So we're asking for your help. Please fill out the following poll with the version of PHP that is on the server you're using for PHP.
How to find your PHP version
The Admin -> About page in your ProofBuddy admin pages will show you the version on your server. For example, the screenshot to the right shows version 5.3
For this poll we're lumping all version 4s into one choice. So if you see PHP 4 point anything please select version 4 in the poll.
Why the change
The biggest push is that PHP 5 offers features that PHP 4 does not, and we feel comfortable with this change since the end of life for PHP version 4 was announced more than 4 years ago and updates to PHP officially stopped in August of 2008.
The other factor is that WordPress has announced that WordPress 3.1 will be the last version to support PHP 4 and they are targeting version 5.2 for version 3.2. With the popularity of WordPress we feel that hosts that are still using a 4-year-old version of PHP will be forced to update or risk losing clients.
What if my host is still using PHP4?
The easiest answer is to find a new host. Of course that may or may not be realistic.
Many hosts - notably GoDaddy - offer both PHP 4 and PHP 5, and it seems that most of them use PHP 4 by default. But, there is typically a setting in your hosting control panel to switch to PHP 5.
