PHP5.6 is, at the date of writing this, in the first beta phase. So the good question is: What new and cool features can we expect in the shiny new PHP-Version?
- Exponential operator
- importing namespaced functions
- constant scalar expressions
- variadic functions
- argument unpacking
- phpdbg
- Streams for POST-data
- Default Character-Encoding improvements
- TLS improvements
- More “under-the-hood”-Improvements
For a full list of changes have a look at the RFC-Part of the php.net wiki
