2 days ago - Because it contained features originally intended to be part of 6.0, PHP 5.3 was a significant release, adding support for namespaces, closures, late static binding, and many fixes and improvements to standard functions.

r/PHP on Reddit: Does Anyone Still Need PHP 5 Support in 2024?
April 19, 2024 -
UPDATE (2024-04-19)
https://github.com/paragonie/sodium_compat/pull/171 -- We've decided to go ahead with a new major version. The original comment is below the line.
We maintain polyfill libraries (random_compat and sodium_compat, which many of you use as a recursive dependency).
Both tentatively support PHP 5.2.4 through the current version (8.4 is coming later this year). This minimum version was specified to ensure our libraries could be used by projects like WordPress.
WordPress requires PHP 7 today.
Does anyone still require support for PHP 5 today? If so, please let us know.
Otherwise, we plan on releasing a new major version for sodium_compat that cuts off support for PHP 5, and sunsetting random_compat (since it's pointless in PHP 7+).
We're aware of Packagist statistics, etc. but that doesn't speak much to the long tail of unpopular projects that haven't made the transfer (esp. if they use an Enterprise OS that backports patches until the heat death of the universe).
We have, previously, explored what a 2.x version of the library may look like. Just using scalar type declarations cut down a lot of the code size.

I think you should cut off support for PHP 5 if nothing else just to do your bit to finally push any organisations or projects still on 5 into finally upgrading.

Just because you stop supporting PHP 5 in your future releases doesn't mean your current releases go away or stop working. If some PHP5 sites are using your polyfill, then they can just keep using the last PHP5 compatible version of it. PHP 5 is still widely used in legacy situations, I can't imagine many are actually developing stuff in it, just keeping the lights on.

March 3, 2022 - The first release of PHP was in 1995 and it’s usage grew rapidly. Regular version updates providing additional functionalities were pushed until 2014, when PHP 5.6 was released. But in 2014 it was already too late. PHP from the very beginning was very easy to use and learn and was a very forgiving language – which was both it’s reason for great success and trouble on the other hand.
