#50696 [NEW]: number_format when passed a 0 as first function argument, returns null

From: endosquid at endosquid dot com Operating system: Linux 32 bit PHP version: 5.3.1 PHP Bug Type: Math related Bug description: number_format when passed a 0 as first function argument, returns null Description: ------------ php -r 2>/dev/null 'print number_format("",0) . "\n";' on our old PHP 5.1.6 Solaris 8 box (that we are transitioning off of) returns 0. Now, we're testing our code, and we run into this behavior change: php -r 2>/dev/null 'print number_format("",0) . "\n";' on our new RHEL5 with 5.3.1 from the REMI repository returns NULL. Is this the default behavior expected? If so, why did this change happen? If not, where did we go wrong? Reproduce code: --------------- php -r 2>/dev/null 'print number_format("",0) . "\n";' Expected result: ---------------- We expect to see 0 returned, not NULL. Actual result: -------------- NULL is returned. -- Edit bug report at http://bugs.php.net/?id=50696&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50696&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50696&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50696&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50696&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50696&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50696&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50696&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50696&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50696&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50696&r=support Expected behavior: http://bugs.php.net/fix.php?id=50696&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50696&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50696&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50696&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50696&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50696&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50696&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50696&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50696&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50696&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50696&r=mysqlcfg
