#34113 [Opn->Fbk]: mb_ereg_replace does not function as it should under "UTF-8"

ID: 34113 Updated by: sniper@php.net Reported By: mlmlml at lily dot freemail dot ne dot jp -Status: Open +Status: Feedback Bug Type: mbstring related Operating System: windows 2000 server PHP Version: 4.3.11 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Previous Comments: ------------------------------------------------------------------------ [2005-08-13 01:15:17] mlmlml at lily dot freemail dot ne dot jp Description: ------------ When "mb_ereg_replace" is used under "UTF-8" source environment, it does not seem to recognize gmulti-byte spaceh (zenkaku-space in Japanese). The same code runs correctly under gEUC-JPh source environment, so I supposed this was something buggy rather than mis-usage of the function. [mbstring] mbstring.language = Japanese mbstring.internal_encoding = UTF-8 mbstring.http_input = auto mbstring.http_output = UTF-8 ;mbstring.encoding_translation = Off mbstring.detect_order = auto mbstring.substitute_character = none; ;mbstring.func_overload = 0 Reproduce code: --------------- <?php /* the all three var_dump()s "UTF-8", and this verifies the source is actually run under "UTF-8" */ var_dump(mb_regex_encoding()); var_dump(mb_internal_encoding()); mb_regex_encoding(mb_internal_encoding()); var_dump(mb_regex_encoding()); /* Although this var_dump should give "**********@*****" by recognising "@"(multi-byte space), when it is run under "UTF-8", it gives "****************". This assures that the "multi-byte space" is not recognised as it should. */ $string = "multi-byte@space"; var_dump(mb_ereg_replace('[^@]', '*', $string)); ?> Expected result: ---------------- multi-byte space should not be converted to "*" in the reproduce code since the regular expression is "[^@]". Actual result: -------------- multi-byte space is ignored and converted to "*". ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34113&edit=1
