Description: ------------ ctype_lower detects non-lower characters when the local is set to 'en_US.UTF-8' on Mac OSX 10.8. This phenomenon cannot't be reproduced on Ubuntu Linux. This phenomenon means ctype_lower detects Chinese characters and Hangul (Korean Alphabet) which have no concept about lower and upper cases. The test cases for C language and showing misdetected characters can be seen here: https://gist.github.com/masakielastic/5828106 The tests for BSD-compatible OSes are needed judging from Xcode's manual. http://developer.apple.com/library/Mac/documentation/Darwin/Reference/ManPages/m an3/islower.3.html ctype_upper also detects non-upper characters. Test script: --------------- $expected = []; $result = []; for ($i = 0; $i <= 0xFF; ++$i) { setlocale(LC_ALL, 'C'); if (ctype_lower(chr($i))) { $expected[] = $i; } setlocale(LC_ALL, 'en_US.UTF-8'); if (ctype_lower(chr($i))) { $result[] = $i; } } var_dump( [] === array_diff($result, $expected) ); Expected result: ---------------- bool(true) Actual result: -------------- bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=65080&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65080&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65080&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65080&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65080&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65080&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65080&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65080&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65080&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65080&r=support Expected behavior: https://bugs.php.net/fix.php?id=65080&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65080&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65080&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65080&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65080&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65080&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65080&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65080&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65080&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65080&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65080&r=mysqlcfg
