note 119296 added to function.strtolower

When the locale is set to "utf8" or "C" I can't get strtolower() to convert accented characters encoded as UTF-8, so here is my workaround. <?php function tolower($string) { if ($old_locale = setlocale(LC_CTYPE, 0)) { // 'fr_FR.ISO-8859-1' for *nix, 'French_France.1252' fallback for Windows if ($newlocale = setlocale(LC_CTYPE, 'fr_FR.ISO-8859-1', 'French_France.1252')) { preg_match('/\.(?<encoding>.+)$/', $newlocale, $match); $string = utf8_encode(strtolower(utf8_decode($string))); } setlocale(LC_CTYPE, $old_locale); } return $string; } print(tolower('DÉJÀ-VU')); // prints déjà-vu ?> Change the language-country codes if you want some language other than French. ---- Server IP: 72.52.91.14 Probable Submitter: 211.30.51.139 ---- Manual Page -- http://php.net/manual/en/function.strtolower.php Edit -- https://master.php.net/note/edit/119296 Del: integrated -- https://master.php.net/note/delete/119296/integrated Del: useless -- https://master.php.net/note/delete/119296/useless Del: bad code -- https://master.php.net/note/delete/119296/bad+code Del: spam -- https://master.php.net/note/delete/119296/spam Del: non-english -- https://master.php.net/note/delete/119296/non-english Del: in docs -- https://master.php.net/note/delete/119296/in+docs Del: other reasons-- https://master.php.net/note/delete/119296 Reject -- https://master.php.net/note/reject/119296 Search -- https://master.php.net/manage/user-notes.php
