README

This library parse versions, E.x.: 1.0.0 1.0.2-stable 1.0.20-alpha2. It can parse constraints (like Composer versions), E.x.: >=1.0 >=1.0,<2.0 >=1.0,<1.1 | >=1.2, 1.0.*, ~1.2.

The goal of that is to let you check if a version matches a constraint, or to check if a constraint is a subset of another constraint.

All that is done to let us select which version is compatible with a user constraints.

It works with the same rules of Composer versioning.

Sorting

In order to use standard PHP sorting there is a helper class 'Compare' to use it with a sort you will need to do this;

use Version\Version;
use Version\Compare;

$vers = array();
$vers[] = Version::parse('1.1.1d1');
$vers[] = '1.1.1';

$obj = new Compare();
usort( $vers, array( $obj, 'compare' ) );

The above should allow any normal PHP sort to be instigated with very little effort.

Note: You should see that it will handle a string or a Version object as the variable to sort automatically.
