note 124090 added to function.strcoll

You should not rely on this function to properly compare localized strings. <?php $a = "Österreich"; $b = "Oesterreich"; $z = "Zeta"; echo setlocale(LC_ALL, 0) . PHP_EOL; // (on my mac: C/en_US.UTF-8/C/C/C/C) echo strcoll($a, $b) . PHP_EOL; // 116 echo strcoll($b, $a) . PHP_EOL; // -116 echo strcoll($a, $z) . PHP_EOL; // 105 echo setlocale(LC_ALL, "de_DE") . PHP_EOL; // de_DE echo strcoll($a, $b) . PHP_EOL; // 135 echo strcoll($b, $a) . PHP_EOL; // -135 echo strcoll($a, $z) . PHP_EOL; // 124 $collator = new Collator("de_DE"); echo $collator->compare($a, $b); // 1 echo $collator->compare($b, $a); // -1 echo $collator->compare($a, $z); // -1 ?> Using the Collator (from the intl module) you will get the expected result for e.g. sorting such that the string "Österreich" will rank higher than "Zeta", but after "Oesterreich". strcoll's output will differ per platform, locale and used c library, while the Collator will give more stable results on different platforms. ---- Server IP: 208.43.231.9 Probable Submitter: 185.85.3.195 (proxied: 2001:1c02:1001:c300:5554:6cb:178c:9f9e) ---- Manual Page -- http://php.net/manual/en/function.strcoll.php Edit -- https://master.php.net/note/edit/124090 Del: integrated -- https://master.php.net/note/delete/124090/integrated Del: useless -- https://master.php.net/note/delete/124090/useless Del: bad code -- https://master.php.net/note/delete/124090/bad+code Del: spam -- https://master.php.net/note/delete/124090/spam Del: non-english -- https://master.php.net/note/delete/124090/non-english Del: in docs -- https://master.php.net/note/delete/124090/in+docs Del: other reasons-- https://master.php.net/note/delete/124090 Reject -- https://master.php.net/note/reject/124090 Search -- https://master.php.net/manage/user-notes.php
