Previous Comments: ------------------------------------------------------------------------ [2009-05-18 12:12:50] a at b dot c dot de You could use the existing "version_compare" function instead of writing your own. That would cover the PHP version-numbering convention. Other conventions could be addressed by hand-written functions, but given the existence of those other conventions a single "SORT_VERSION" flag wouldn't be sufficient. ------------------------------------------------------------------------ [2009-05-16 18:49:07] sean at wdsolutions dot com 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 this bug report at https://bugs.php.net/bug.php?id=48305&edit=1
