Version

Value Object representing a version number that is in compliance with the Semantic Versioning specification.

Installation

The preferred method of installation is via Composer. Run the following command to install the latest version of a package and add it to your project's composer.json:

composer require nikolaposa/version

Usage

Creating a Version object via named constructor and accessing its values

use Version\Version;

$v = Version::fromPreRelease(2, 0, 0, 'alpha');

echo $v->getMajor(); //2
echo $v->getMinor(); //0
echo $v->getPatch(); //0
var_dump($v->getPreRelease()->getIdentifiers()); //array(1) { [0]=> string(1) "alpha" }
echo $v->getPreRelease(); //alpha

Creating a Version object from a string

use Version\Version;

$v = Version::fromString('1.10.0');

echo $v->getVersionString(); //1.10.0

Comparing Version objects

use Version\Version;

$v1 = Version::fromString('1.10.0');
$v2 = Version::fromString('2.3.3');

var_dump($v1->isLessThan($v2)); //bool(true)
var_dump($v1->isGreaterThan($v2)); //bool(false)
var_dump($v1->isEqualTo($v2)); //bool(false)

var_dump($v2->isLessThan($v1)); //bool(false)
var_dump($v2->isGreaterThan($v1)); //bool(true)

Modifying version

use Version\Version;

$v = Version::fromString('1.10.0');

$v1101 = $v->withPatchIncremented();
echo $v1101; //1.10.1

$v1110 = $v1101->withMinorIncremented();
echo $v1110; //1.11.0

$v2 = $v1101->withMajorIncremented();
echo $v2; //2.0.0-alpha

$v2Alpha = $v2->withPreRelease('alpha');
echo $v2Alpha; //2.0.0-alpha

$v2Alpha111 = $v2Alpha->withBuild('111');
echo $v2Alpha111; //2.0.0-alpha+111

Version-aware objects

use Version\Version;
use Version\VersionAwareInterface;
use Version\VersionAwareTrait;

class Package implements VersionAwareInterface
{
    use VersionAwareTrait;

    private $name;

    private $description;

    public function __construct($name, $description = '')
    {
        $this->name = $name;
        $this->description = $description;
    }

    public function getName()
    {
        return $this->name;
    }

    public function getDescription()
    {
        return $this->description;
    }
}

$package = new Package('Test');
$package->setVersion(Version::fromString('2.3.3'));

Versions collection

use Version\VersionsCollection;
use Version\Version;

$versions = new VersionsCollection([
    Version::fromMajor(1),
    '1.1.0',
    '2.3.3',
]);

echo count($versions); //3

//Sort descending
$versions->sort(true);

//Outputs: 2.3.3, 1.1.0, 1.0.0
foreach ($versions as $version) {
    echo (string) $version;
}
