Needed a quick way to sort on version numbers, and PHP has a usort function that makes it pretty easy.
You’ll need an array to sort and call the usort function with a callback.
$ray = array("1.1", "2.4", "0.7", "1.1.b"); usort($ray, 'versionSort');
Now the callback. We’re going to use version_compare.
function versionSort($a, $b) { return -1 * version_compare($a, $b); }
Only minor quirk is the * -1 to flip version compare. I wanted the newest version at the 0 spot. You could also just swap $a and $b to do the same thing. This just made more sense to me for when I come back and look at it down the road.
Oops, forgot to wrap the version numbers in quotes. Fixed now…
usort($ray, ‘version_compare’);
$ray = array_reverse($ray);
