Andi, Is there a guide somewhere for those who are PHP developers, not C developers, who would want to try existing code under PHP 6 but don't know all the ins and outs of the new unicode system? It sounds like there's 3-4 unicode switches in php.ini, but maybe I'm missing some and I'm sure I don't fully understand what they're all supposed to do.
I mean a single-sourced guide along the lines of: - Get PHP-free system. - Download this file: - Untar, run make install. - Do X to get the mysql(i) driver in there too (since more apps use that than PDO right now). - Tour of the new php.ini switches to play with and what they mean/do: - Try running your app. Known places where there may be issues: (Johannes' earlier post is a great starting point) - Please direct reports on your successes and what broke to: A "PHP 6 testers' instruction manual" would probably make it a lot easier to be a PHP 6 tester. :-) On Tuesday 21 August 2007, Andi Gutmans wrote: > If there's an overwhelming support for removing the switch then I guess > that's where it is.
