Dependency management is a crucial part when developing PHP projects. I recently encountered a headache when working on a project: updates to project dependencies caused some parts of the code to fail. This is because I rely on some "soft dependencies" that are not explicitly defined in composer.json. To solve this problem, I found a very useful tool - maglnet/composer-require-checker, which helped me detect and resolve these dependencies and improve the robustness of the project.

maglnet/composer-require-checker is a CLI tool that analyzes composer dependencies and verifys whether unknown symbols are used in the code. It can effectively prevent you from using "soft dependencies" that are not defined in the require section of composer.json. For example, if your code uses guzzlehttp/guzzle but is not explicitly declared in composer.json, then this tool will remind you that you should add it as a hard dependency.

Using this tool is very easy. You can download PHAR files, or install them globally via PHIVE or Composer. The following are the commands installed globally through Composer:

 <code>composer global require maglnet/composer-require-checker</code>

After the installation is complete, you can run the following command to check your project:

 <code>composer-require-checker check composer.json</code>

This tool also checks whether PHP functions are used in the code that require specific extensions to be used and issues warnings if these extensions are not explicitly required.

If you have problems using Xdebug, you can disable it by setting environment variables:

 <code>XDEBUG_MODE=off php composer-require-checker</code>

Additionally, you can customize the configuration files to adjust the behavior of the tool. For example, you can specify additional files to scan:

 <code>{ "scan-files": ["bin/console", "bin/*.php"] }</code>

After using maglnet/composer-require-checker, I was able to quickly identify and resolve dependency issues, ensuring that the project does not experience unexpected errors when dependency updates. This tool not only improves the robustness of the project, but also simplifies the complexity of dependency management, making my development process smoother.

In general, maglnet/composer-require-checker is a very practical tool, especially suitable for PHP projects that require strict management of dependencies. It helps developers avoid the risks brought by "soft dependencies" and ensures the stability and maintainability of their code. If you have similar problems, you might as well try this tool.
