ID: 32219 Updated by: sniper@php.net Reported By: php-france at mattoug dot net -Status: Bogus +Status: Verified Bug Type: Arrays related -Operating System: +Operating System: * -PHP Version: 4.3.8 +PHP Version: 4CVS-2005-03-09 New Comment: It's a bug if *sort() functions can't handle locales correctly. Previous Comments: ------------------------------------------------------------------------ [2005-03-07 23:49:57] derick@php.net No bug here, the functions don't understand locales unless you add as second "sort-flag" parameter SORT_LOCALE_STRING to asort(). This option is introduced in PHP 5.0.2. The following works fine (if you have the fr_FR locale installed): <?php setlocale(LC_ALL, 'fr_FR'); $table = array("AB" => "Alberta", "BC" => "Colombie-Britannique", "MB" => "Manitoba", "NB" => "Nouveau-Brunswick", "NL" => "Terre-Neuve-et-Labrador", "NS" => "Nouvelle-Écosse", "ON" => "Ontario", "PE" => "Île-du-Prince-Édouard", "QC" => "Québec", "SK" => "Saskatchewan", "NT" => "Territoires du Nord-Ouest", "NU" => "Nunavut", "YT" => "Territoire du Yukon"); asort($table, SORT_LOCALE_STRING); var_dump($table); ------------------------------------------------------------------------ [2005-03-07 19:31:22] sniper@php.net With what locale do you expect that output? ------------------------------------------------------------------------ [2005-03-07 14:00:09] php-france at mattoug dot net Description: ------------ Accented characters are not properly sorted. For example, the right sorting of "à" is between "a" and "b", for "é" it's between "e" and "f", and so on... Reproduce code: --------------- $table = array("AB" => "Alberta", "BC" => "Colombie-Britannique", "MB" => "Manitoba", "NB" => "Nouveau-Brunswick", "NL" => "Terre-Neuve-et-Labrador", "NS" => "Nouvelle-Écosse", "ON" => "Ontario", "PE" => "Île-du-Prince-Édouard", "QC" => "Québec", "SK" => "Saskatchewan", "NT" => "Territoires du Nord-Ouest", "NU" => "Nunavut", "YT" => "Territoire du Yukon"); asort($table); Expected result: ---------------- array(13) { ["AB"]=> string(7) "Alberta" ["BC"]=> string(20) "Colombie-Britannique" ["PE"]=> string(21) "Île-du-Prince-Édouard" ["MB"]=> string(8) "Manitoba" ["NB"]=> string(17) "Nouveau-Brunswick" ["NS"]=> string(15) "Nouvelle-Écosse" ["NU"]=> string(7) "Nunavut" ["ON"]=> string(7) "Ontario" ["QC"]=> string(6) "Québec" ["SK"]=> string(12) "Saskatchewan" ["NL"]=> string(23) "Terre-Neuve-et-Labrador" ["YT"]=> string(19) "Territoire du Yukon" ["NT"]=> string(25) "Territoires du Nord-Ouest"} Actual result: -------------- array(13) { ["AB"]=> string(7) "Alberta" ["BC"]=> string(20) "Colombie-Britannique" ["MB"]=> string(8) "Manitoba" ["NB"]=> string(17) "Nouveau-Brunswick" ["NS"]=> string(15) "Nouvelle-Écosse" ["NU"]=> string(7) "Nunavut" ["ON"]=> string(7) "Ontario" ["QC"]=> string(6) "Québec" ["SK"]=> string(12) "Saskatchewan" ["NL"]=> string(23) "Terre-Neuve-et-Labrador" ["YT"]=> string(19) "Territoire du Yukon" ["NT"]=> string(25) "Territoires du Nord-Ouest" ["PE"]=> string(21) "Île-du-Prince-Édouard" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32219&edit=1
