Bug #62112 [NEW]: Regression in number_format() in PHP 5.4

From: lstrojny Operating system: Linux PHP version: 5.4.3 Package: Math related Bug Type: Bug Bug description:Regression in number_format() in PHP 5.4 Description: ------------ In PHP 5.3.X, passing a null byte as decimal point lead to no decimal point at all. This is not so much problematic for userland, as for C extensions. For examlpe phpredis uses it internally (see https://github.com/nicolasff/phpredis/blob/master/redis.c#L3665) to format a number. This worked fine in PHP 5.3, but with PHP 5.4 only the first character until the first decimal point is returned. Test script: --------------- php -r 'var_dump(number_format(2000.1, 0, ".", "\x00"));' Expected result: ---------------- string(4) "2000" Actual result: -------------- string(1) "2" -- Edit bug report at https://bugs.php.net/bug.php?id=62112&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62112&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62112&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62112&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62112&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62112&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62112&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62112&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62112&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62112&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62112&r=support Expected behavior: https://bugs.php.net/fix.php?id=62112&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62112&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62112&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62112&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62112&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62112&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62112&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62112&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62112&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62112&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62112&r=mysqlcfg
