I know PHP6 is probably a ways off, but it's interesting that they're already adding documentation for it:
unicode.fallback_encoding NULL PHP_INI_ALL Available since PHP 6.0.0.
unicode.from_error_mode "2" PHP_INI_ALL Available since PHP 6.0.0.
unicode.from_error_subst_char "3f" PHP_INI_ALL Available since PHP 6.0.0.
unicode.http_input_encoding NULL PHP_INI_ALL Available since PHP 6.0.0.
unicode.output_encoding NULL PHP_INI_ALL Available since PHP 6.0.0.
unicode.runtime_encoding NULL PHP_INI_ALL Available since PHP 6.0.0.
unicode.script_encoding NULL PHP_INI_ALL Available since PHP 6.0.0.
unicode_semantics "off" PHP_INI_PERDIR Available since PHP 6.0.0.
INI List
So... any word on if PHP 6 is gonna be released in 2006 or will we be waiting a while longer?
And, if they're pumping out ver. 6 now, is it even worth it to ask hosts to upgrade to PHP5?
