Derick, i know this is the initial dump, but have a look also here : http://icu.sourceforge.net/userguide/Collate_ServiceArchitecture.html#Sort_Key
For small lists the current implementation is OK, but after a threshold, sort keys are better performance-wise. Here's an implementation of mine (untested, unfortunately) which attempts to use sort-keys as well as accomodating iterators (search for "sort"). Never mind the use of the C++ API, the concept is the same. http://cvs.iworks.at/co.php/php-i18n/collator.cpp?r=1.3 I actually have a different implementation (strictly C) which switches between ucol_compare and sort-key generation after a threshold, but i havent had time to work on it. l0t3k ""Derick Rethans"" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > derick Sun Mar 26 11:06:24 2006 UTC > > Added files: > /php-src/ext/unicode collator.c > > Modified files: > /php-src/ext/standard array.c php_array.h > /php-src/ext/unicode config.m4 config.w32 php_unicode.h unicode.c > Log: > - Implemented basic collation support.
