As Manuel Lemos mentions in his most recent blog post the official name for the next major release of the PHP language has been decided...and no, it's not PHP 6. Based on the results of this vote, the next major version will start off the PHP 7 series.
Manuel talks about some of the reasoning behind skipping over the PHP 6 naming and how it's possible that the PHPNG branch could become the base for PHP 7. Some of the improvements in this release could include:
- Huge Performance Improvements
- JIT (Just In Time) Engine
- AST: Abstract Syntax Tree
As it stands now, there's no predicted release date for PHP 7, but guesses put it between one to three years out, depending on the functionality it plans to include.
