Bug #64912 [NEW]: Unexpected output when parsing PHP files containing NUL characters

From: alexander dot stehlik at gmail dot com Operating system: Linux (Ubuntu and CentOS) PHP version: 5.4.15 Package: mbstring related Bug Type: Bug Bug description:Unexpected output when parsing PHP files containing NUL characters Description: ------------ When this setting is used: zend.multibyte = On and I parse a PHP file that contains a NUL character (this one here: http://en.wikipedia.org/wiki/Null_character) I get some weird output. When I do not use the mbstring.internal_encoding setting I get a lot of question marks (?). When I use mbstring.internal_encoding = utf-8 I get some characters that look like Chinese to me. Test script: --------------- <?php // I can not insert the NUL character here. // To put it in a PHP file you can use the console: // // echo -e "here is \0 null" >> test.php $var = 'here is <InsertNULCharacterHere> null'; ?> Expected result: ---------------- When I run the given example with php test.php I expect no output, even when this setting is active: zend.multibyte = On Actual result: -------------- With the setting zend.multibyte = On I get some weird output (depending on the configured internal encoding): With the setting mbstring.internal_encoding = utf-8 I get an output that looks like this: 㰿灨瀊⑶慲‽‧桥物⁳椠 湵汬✻ਿ㸊 Without the setting the output looks like this: ??????????? ????? -- Edit bug report at https://bugs.php.net/bug.php?id=64912&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64912&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64912&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64912&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64912&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64912&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64912&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64912&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64912&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64912&r=support Expected behavior: https://bugs.php.net/fix.php?id=64912&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64912&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64912&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64912&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64912&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64912&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64912&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64912&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64912&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64912&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64912&r=mysqlcfg
