PHP 5.6.0 has been released last month by the PHP Development Team. This new version includes some major changes and many improvements. See the release note.

phpdbg, Interactive PHP debugger

Main features added:

  • Constant scalar expressions.
  • Variadic functions and argument unpacking using the ... operator.
  • Exponentiation using the ** operator.
  • Function and constant importing with the use keyword.
  • phpdbg as an interactive integrated debugger SAPI.
  • php://input is now reusable, and $HTTP_RAW_POST_DATA is deprecated.
  • GMP objects now support operator overloading.
  • File uploads larger than 2 gigabytes in size are now accepted.
