Doc #68842 [NEW]: mb_check_encoding() behavior does not match document

From: yohgaki Operating system: Irerelevant PHP version: Irrelevant Package: mbstring related Bug Type: Documentation Problem Bug description:mb_check_encoding() behavior does not match document Description: ------------ http://php.net/mb_check_encoding says, var The byte stream to check. If it is omitted, this function checks all the input from the beginning of the request. This description is misleading. What mbstring does is Return TRUE if all conversions since the execution of the script has no problems at all. Return FALSE if there is any conversion errors in mbstring operations. If input encoding conversion is done, all inputs (GPC) are converted from mbstring.http_input encoding to mbstring.internal_encoding. If input encoding conversion is not done, it cannot be used for input encoding checks. I think it's better to check GET/POST/COOKIE encodings, but it was made this way since the introduction, I guess. (I think 1st param was not optional at first, but I don't remember well.) -- Edit bug report at https://bugs.php.net/bug.php?id=68842&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68842&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68842&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68842&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68842&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68842&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68842&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68842&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68842&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68842&r=support Expected behavior: https://bugs.php.net/fix.php?id=68842&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68842&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68842&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68842&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68842&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68842&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68842&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68842&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68842&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68842&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68842&r=mysqlcfg
