Req #68480 [NEW]: unpack unsigned large number becoming negative

From: ignasimg at gmail dot com Operating system: Irrelevant PHP version: Irrelevant Package: *General Issues Bug Type: Feature/Change Request Bug description:unpack unsigned large number becoming negative Description: ------------ According to the documentation page about unpack: http://php.net/manual/en/function.unpack.php Caution [...] If you unpack a large unsigned long and it is of the same size as PHP internally stored values the result will be a negative number even though unsigned unpacking was specified. My question (beside wtf?) is would it be so hard to specify inside the unpack function that if unsigned was required make it become unsigned? I mean... it might sound stupidly ridicoulous but why is there an unsigned format if it acts the same as with signed? There's even some funny solution on the same page comments: if ($unpackedVal <0) { $unpackedVal += 4294967296; } which is platform dependent and probably inefficient. But since I have no idea about the inner workings of PHP my question again is would it be so difficult to make it behave properly? -- Edit bug report at https://bugs.php.net/bug.php?id=68480&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68480&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68480&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68480&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68480&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68480&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68480&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68480&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68480&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68480&r=support Expected behavior: https://bugs.php.net/fix.php?id=68480&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68480&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68480&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68480&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68480&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68480&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68480&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68480&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68480&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68480&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68480&r=mysqlcfg
