PHP 5.6, PHPNG and Onwards

PHP is still under active development and there are some very interesting
changes and features that are coming to the language.

## PHP 5.6

PHP 5.6 is currently in RC (release candidate) status, which means it will be
officially released soon (I suspect in the next few months).

Here’s a highlight of the new features:

* [Constant scalar expressions](
* [Variadic functions](
* [Argument unpacking](
* [Namespace use function and use const](
* [Exponential syntax](

We’ve been making changes to Komodo 9 to support PHP 5.6, for code highlighting,
code intelligence and debugging components. You can get the [Komodo
9 pre-release](/download/#preview) build from our downloads page.


A development branch currently being referred to as PHP Next Generation (PHPNG)
is looking very promising. It’s mostly a refactoring of the PHP (Zend Engine)
internals, with the aim to increase PHP performance.

So far, performance has been improved by 100% in real world applications, whilst
still maintaining API compatibility – that’s totally awesome, and generally
unheard of in the dynamic languages arena, especially for such a mature language
like PHP. All in all, amazing improvements and I cannot wait to see the final
release containing this work!

This is purely speculation, but I think these PHPNG changes may eventually
become the center piece for a PHP 6.0 version (maybe next year).

You can read more about the changes going on in PHPNG here:

## PHP 5.3

It’s also worth looking back at older versions too, as PHP 5.3 is already
end-of-lifed, with official support ending July 2014 (this month), so no more
security fixes can be expected for PHP 5.3.
