From: mk at zigamorph dot se Operating system: Linux PHP version: 5.2.10 PHP Bug Type: Scripting Engine problem Bug description: mb_strcut cutting wrong length when offset is within a multibyte character
Description: ------------ When you use mb_strcut with an offset and this offset happens to fall within a multibyte (utf-8) character mb_strcut moves the start point of the string as to not break a multibyte character. As an undesirable side effect it strips one or more bytes from the end of the cut string. Reproduce code: --------------- $crap = 'AåBäCöDü' /* in utf-8 */ echo mb_strcut($crap, 0, 100, 'UTF-8')."\n"; /* 'AåBäCöDü' as 100 is more than strlen */ echo mb_strcut($crap, 1, 100, 'UTF-8')."\n"; /* 'åBäCöDü' as 100 is more than strlen and we're offset 1 byte */ echo mb_strcut($crap, 2, 100, 'UTF-8')."\n"; /* 'åBäCöD' */ Expected result: ---------------- $crap = 'AåBäCöDü' /* in utf-8 */ echo mb_strcut($crap, 0, 100, 'UTF-8')."\n"; /* 'AåBäCöDü' as 100 is more than strlen */ echo mb_strcut($crap, 1, 100, 'UTF-8')."\n"; /* 'åBäCöDü' as 100 is more than strlen and we're offset 1 byte */ echo mb_strcut($crap, 2, 100, 'UTF-8')."\n"; /* either 'åBäCöDü' or 'BäCöDü' */ -- Edit bug report at http://bugs.php.net/?id=49354&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49354&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49354&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49354&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49354&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49354&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49354&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49354&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49354&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49354&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49354&r=support Expected behavior: http://bugs.php.net/fix.php?id=49354&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49354&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49354&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49354&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49354&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49354&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49354&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49354&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49354&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49354&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49354&r=mysqlcfg
