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;
}
