This RFC proposes to extend the End of Active Support & End of Security Support dates for PHP 5.6, the final version in the PHP 5 family.
The release of PHP 7.0 is the first time a major version of PHP is released under the new Release Process RFC. While the RFC did outline rules for major versions, most of the discussion prior to the RFC, as well as all of the experience we've gained on the ground since its introduction dealt with how we deal with minor versions, as back then a major version wasn't actively being discussed. In addition, the release of PHP 7.0 happened substantially later than the 'standard' mid-year release cycle that most prior versions of PHP adhered to.
The currently published timeline for PHP 5.6 suggests an end to active support on August 28, 2016 and end to security support on August 28, 2017 - approximately 8 months & 20 months (respectively) after the release of PHP 7.0. Many consider these timeline inadequate for two key reasons:
In addition, PHP 7 breaks source-level compatibility with PHP 5.x - which means extensions will not work (or even build) on PHP 7 without substantial refactoring. This refactoring typically amounts to much more than just fixing some compilation errors, due to fundamental changes to the underlying data structures of the engine. Extending the support period for PHP 5 will allow users of custom extensions - as well as PECL extensions which haven't yet been upgraded - to have more time to port and test them, as well as their code that uses them. It's worth noting that much of the development effort of PHP 7 since the introduction of the PHPNG engine was focused around porting extensions to build and work on PHP 7 - this is not an easy task.
It is proposed to reschedule both the End of Active Support and End of Security Support to provide the PHP userbase a longer, but still clear upgrade timeline. Most people feel that it is more important to further push the End of Security Support date, compared to the End of Active Support date.
This RFC recommends to extend the Active Support period to a full year, followed by two additional years of Security Support. In total, it provides three different options to choose from:
There are two main downsides to pushing the support dates for PHP 5.6:
That said, many believe that sticking with the current timeline (option #3) is simply too aggressive, and we should at least go for option #2 as it gives people at least the same amount of time they had to upgrade from 5.5 to 5.6, to upgrade from 5.6 to 7.0.
Further, given the 5.6 -> 7.0 upgrade is more difficult and time consuming - the recommendation of this RFC is to go with option #1. The importance of giving users a bit more time to upgrade was also alluded to in the PHP 5.7 RFC, although it was rejected - mainly due to concerns about defocusing the efforts of releasing PHP 7.0 - concerns which are no longer relevant now that 7.0 has been successfully released.
Several people recommended that the Release Process RFC be amended to align the End of Support dates for a given version to the release of subsequent versions, also for minor releases. This is outside the scope of this proposal - which deals specifically with the support timelines of PHP 5.6 - and would be proposed in a separate RFC.
In case the majority chooses to extend the lifetime of PHP 5.6 (>50%) - then the option garnering more votes between the two proposed timelines would win.
