composer/semver =============== Semver library that offers utilities, version constraint parsing and validation. Originally written as part of [composer/composer](https://github.com/composer/composer), now extracted and made available as a stand-alone library. [](https://travis-ci.org/composer/semver) Installation ------------ Install the latest version with: ```bash $ composer require composer/semver ``` Requirements ------------ * PHP 5.3.2 is required but using the latest version of PHP is highly recommended. Version Comparison ------------------ For details on how versions are compared, refer to the [Versions](https://getcomposer.org/doc/articles/versions.md) article in the documentation section of the [getcomposer.org](https://getcomposer.org) website. Basic usage ----------- ### Comparator The `Composer\Semver\Comparator` class provides the following methods for comparing versions: * greaterThan($v1, $v2) * greaterThanOrEqualTo($v1, $v2) * lessThan($v1, $v2) * lessThanOrEqualTo($v1, $v2) * equalTo($v1, $v2) * notEqualTo($v1, $v2) Each function takes two version strings as arguments. For example: ```php use Composer\Semver\Comparator; Comparator::greaterThan('1.25.0', '1.24.0'); // 1.25.0 > 1.24.0 ``` ### Semver The `Composer\Semver\Semver` class provides the following methods: * satisfies($version, $constraints) * satisfiedBy(array $versions, $constraint) * sort($versions) * rsort($versions) License ------- composer/semver is licensed under the MIT License, see the LICENSE file for details.
