PHP Semantic Versioning Helper

SemVer is a semantic versioning helper library for PHP by Chris Kankiewicz with support for parsing, incrementing, and comparison.

Here’s the basic usage which initializes a SemVer\Version object:

use PHLAK\SemVer;

$version = new SemVer\Version(); // Initilializes to '0.1.0'

With an instance of SemVer\Version you can access individual values:

$version = new SemVer\Version('v1.2.3-beta.4+007');

echo $version;             // '1.2.3-beta.4+007'
echo $version->major;      // 1
echo $version->minor;      // 2
echo $version->patch;      // 3
echo $version->preRelease; // 'beta.4'
echo $version->build;      // '007'

If you wanted to build something that increments your package builds you can use this package’s increment methods:

$version = new SemVer\Version('v1.2.3');

$version->incrementMajor(); // v1.2.3 -> v2.0.0
$version->incrementMinor(); // v1.2.3 -> v1.3.0
$version->incrementPatch(); // v1.2.3 -> v1.2.4

Last, the comparisons are pretty handy:

$version1 = new SemVer('v1.2.3');
$version2 = new SemVer('v3.2.1');

$version1->gt($version2);  // false
$version1->lt($version2);  // true
$version1->eq($version2);  // false
$version1->neq($version2); // true
$version1->gte($version2); // false
$version1->lte($version2); // true

Before checking out this PHLAK/SemVer, I wasn’t aware that composer also has a composer/semver library, which has a comparator and semver class, however, I didn’t find the increment methods found in PHLAK/SemVer.

To get installation instructions, check out PHLAK/SemVer on GitHub!
