Secret to unlock PHAR files: Easily read and create manifest files using the phar-io/manifest library

You can learn composer through the following address:

I'm having a tricky problem when working with PHAR files: I can't read and manage manifest files efficiently (manifest.xml). This caused my project to make frequent errors during deployment and updates, affecting development progress. After trying multiple methods, I finally found the phar-io/manifest library, which is specifically used to read and create manifest information for PHAR files.

Install phar-io/manifest

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

 <code class="bash">composer require phar-io/manifest</code>

If you are just using this library during development, such as running a test suite, you can install it as a development dependency:

 <code class="bash">composer require --dev phar-io/manifest</code>

Example of usage

Read information from manifest.xml file

Suppose you have a manifest.xml file, you can use the ManifestLoader class to read its contents:

 <code class="php">use PharIo\Manifest\ManifestLoader; use PharIo\Manifest\ManifestSerializer; $manifest = ManifestLoader::fromFile('manifest.xml'); var_dump($manifest); echo (new ManifestSerializer)->serializeToString($manifest);</code>

In this way, you can easily obtain and view detailed information in the manifest file, including application name, version, copyright information, etc.

Create manifest file through API

You can also create manifest files dynamically through the API. For example:

 <code class="php">$bundled = new \PharIo\Manifest\BundledComponentCollection(); $bundled->add( new \PharIo\Manifest\BundledComponent('vendor/packageA', new \PharIo\Version\Version('1.2.3-dev')) ); $manifest = new PharIo\Manifest\Manifest( new \PharIo\Manifest\ApplicationName('vendor/package'), new \PharIo\Version\Version('1.0.0'), new \PharIo\Manifest\Library(), new \PharIo\Manifest\CopyrightInformation( new \PharIo\Manifest\AuthorCollection(), new \PharIo\Manifest\License( 'BSD-3-Clause', new \PharIo\Manifest\Url('https://spdx.org/licenses/BSD-3-Clause.html') ) ), new \PharIo\Manifest\RequirementCollection(), $bundled ); echo (new ManifestSerializer)->serializeToString($manifest);</code>

This approach gives you the flexibility to build and customize manifest files to meet the needs of different projects.

Summarize

Using the phar-io/manifest library, I not only solved the problem of reading and creating a PHAR file manifest, but also greatly simplified the management process of the project. The advantage of this library is its ease of use and powerful features, which can be easily handled whether it is reading an existing manifest file or creating a new manifest file on the fly. In practical applications, it significantly improves my development efficiency and ensures the smooth progress of the project. If you also encounter similar problems when dealing with PHAR files, you might as well try this library.
