#48305 [NEW]: SORT_VERSION for sort functions

From: sean at wdsolutions dot com Operating system: Linux PHP version: 5.2.9 PHP Bug Type: Feature/Change Request Bug description: SORT_VERSION for sort functions Description: ------------ It would be awesome to have a SORT_VERSION flag for the sort family of functions, whose behavior would be to sort most common multi-number version strings (with possible support for detecting -cvs, -rc, -svn, and other suffixes). For example, SORT_NUMERIC and SORT_STRING both fail to properly sort the following version numbers: 1.2.1 1.2.2 1.2.10 1.20.5 1.22.50 They get sorted as: 1.20.5 1.2.1 1.2.10 1.2.2 1.22.50 Code I used to work around it is below: Reproduce code: --------------- function vercmp($a, $b) { $as = explode('.', $a); $bs = explode('.', $b); for ($i = 0, $e = max(count($as), count($bs)); $i != $e; ++$i) { if ($as[$i] < $bs[$i]) return -1; elseif ($as[$i] > $bs[$i]) return 1; } return 0; } -- Edit bug report at http://bugs.php.net/?id=48305&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48305&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48305&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48305&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48305&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48305&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48305&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48305&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48305&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48305&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48305&r=support Expected behavior: http://bugs.php.net/fix.php?id=48305&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48305&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48305&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48305&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48305&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48305&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48305&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48305&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48305&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48305&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48305&r=mysqlcfg
