How to use Composer to manage PHP project version number

Composer can be learned through the following address: Learning address

Version control is a key link when managing PHP projects. Recently, I was working on a Git-based PHP project and encountered a problem: how to automatically generate and manage version numbers during development. This problem seems simple, but manual maintenance of the version number is not only cumbersome, but also prone to errors. After some exploration, I found a very useful tool - the sebastian/version library, which was easily integrated into the project through Composer, completely solving my troubles.

Install sebastian/version library

Installing this library using Composer is very simple, just run the following command:

 <code class="language-bash">composer require sebastian/version</code>

If you only use this library during development, such as running a project test suite, you can use it as a development-time dependency:

 <code class="language-bash">composer require --dev sebastian/version</code>

Use sebastian/version library

The main function of the sebastian/version library is to help manage the version number of Git-hosted PHP projects. It is very intuitive to use, just create an instance of SebastianBergmann\Version class and pass two parameters:

• $release : The latest release version number (e.g. XYZ ) or the name of the release series (e.g. XY , used when the branch/release series has not been released yet).
• $path : The path (or its subdirectory) of the directory where the project source code is located. Usually, passing __DIR__ is enough.

Here is a simple example showing the basic usage:

 <code class="language-php"><?php declare(strict_types=1);
use SebastianBergmann\Version;

$version = new Version('1.0.0', __DIR__);

var_dump($version-> asString());</code>

The output may be:

 <code class="language-php">string(18) "1.0.0-17-g00f3408"</code>

When preparing for a new release, just update the first parameter $release passed to the constructor.

How the sebastian/version::asString() method works

• If $path is not part of the Git repository and $release is in XYZ format, then $release is directly returned.
• If $path is not part of the Git repository and $release is in XY format, then $release is returned with the -dev suffix attached.
• If $path is part of the Git repository and $release is in XYZ format, the output of git describe --tags is returned.
• If $path is part of the Git repository and $release is in XY format, a string starting with XY and appending git describe --tags information.

Summary and practical application effects

By using the sebastian/version library, I can not only automatically generate version numbers, but also ensure the accuracy and consistency of version numbers. This library is perfectly combined with Composer, making version management simple and efficient. In practical applications, I found that this tool greatly improves development efficiency, reduces errors in manual maintenance of version numbers, and ensures that the project's version control is more rigorous and standardized. If you are also having difficulties managing version numbers for PHP projects, try using the sebastian/version library, which will bring you unexpected convenience and effects.
