GoPHP5

[BigTom3007]

PHP 4 has served the web developer community for seven years now, and served it well. However, it also shows its age. Most of PHP 4's shortcomings have been addressed by PHP 5, released three years ago, but the transition from PHP 4 to PHP 5 has been slow for a number of reasons.
PHP developers cannot leverage PHP 5's full potential without dropping support for PHP 4, but PHP 4 is still installed on a majority of shared web hosts and users would then be forced to switch to a different application. Web hosts cannot upgrade their servers to PHP 5 without making it impossible for their users to run PHP 4-targeted web apps, and have no incentive to go to the effort of testing and deploying PHP 5 while most web apps are still compatible with PHP 4 and the PHP development team still provides maintenance support for PHP 4. The PHP development team, of course, can't drop maintenance support for PHP 4 while most web hosts still run PHP 4.
It is a dangerous cycle, and one that needs to be broken. The PHP developer community has decided that it is indeed now time to move forward, together. Therefore, the listed software projects have all agreed that effective February 5th, 2008, any new feature releases will have a minimum version requirement of at least PHP 5.2.0. Furthermore, the listed web hosts have agreed that effective February 5th, 2008, they will include PHP 5.2 (or a more recent version) in their service offer.
It is our belief that this will provide web hosts reason to upgrade and the PHP development team the ability to retire PHP 4 and focus efforts on PHP 5 and the forthcoming PHP 6, all without penalizing any existing project for being "first out of the gate".

Will Kayako start supporting PHP 5 as the minimum in any upcoming releases?

Hi Big Tom,

PHP5 is supported (as well as PHP4), but I do not see why we would drop PHP4 support as part of a drive to get everyone using PHP5 - if customers want to continue to use the PHP4 platform, then they may do so and we will not attempt to force otherwise at this time (given how maintstream PHP4 still is).

Yeah many webhost are still using php4...

Jamie, will any tests be done for php6?

Absolutely, updates will be made closer to PHP6's release.

Yea, PHP4 will be around at least 1-2 years yet I think. Phase out is slow which is annoying.

Maybe it's time for Kayako to join http://www.gophp5.org as a few other companies have.

[Jamie Edwards]

We will be continuing support for both PHP4 and PHP5, and will not seek to join the GoPHP4 campaign in case the wrong message is given out that we won't be.

Didn't realise there was already a thread on this (and one I replied to). Sorry.

To quote from the builds page :-

- Changed minimum PHP version from 4.3.0 to 5.1.0 (date/time functionality)

Looks like it is PHP5 only from now on. Nice one Kayako.

Change to minimum server requirements: PHP 5.1.0 is now required - Kayako Community Forums

Nice one guys. We need to push PHP5 a bit more.
