From: masakielastic at gmail dot com Operating system: Mac OS X PHP version: 5.6.6 Package: mbstring related Bug Type: Bug Bug description:mb_ereg should reject ill-formed byte sequence Description: ------------ mb_reg should return false like preg_match if the argument is not well-formed byte sequence since Oniguruma doesn't check the validity of encoding. The same rule applies to mb_ereg_replace, mb_ereg_search_init. Test script: --------------- $str = "\x80"; var_dump( false === mb_eregi('.', $str, $matches), [] === $matches ); Expected result: ---------------- bool(true) bool(true) Actual result: -------------- bool(false) bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=69151&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69151&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69151&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69151&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69151&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69151&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69151&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69151&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69151&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69151&r=support Expected behavior: https://bugs.php.net/fix.php?id=69151&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69151&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69151&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69151&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69151&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69151&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69151&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69151&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69151&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69151&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69151&r=mysqlcfg
