Derick Rethans has posted the notes from the recent PHP 6 meeting in Paris. Looks like quite a few features will be deprecated in PHP 6 - like Register Globals, Magic quotes, Safe mode, Register Long arrays and more.

Some of the additions to the PHP Engine are

1. 64 Bit Integers
2. Goto - The break keyword will be extended to “goto” a static label
3. foreach for multi-dimensional arrays
