How to Manually Install Composer PHP Packages Without Composer?

Manually Installing Composer PHP Packages Without Composer

While Composer simplifies the installation of PHP packages, there are scenarios where direct installation is desired. To bypass the need for Composer, follow these steps:

1. Identify Package Dependencies: Examine the composer.json file of the package to identify its dependencies. For example, for the Coinbase PHP API:

   <code class="json">"require": {
       "php": ">=5.5.0",
       "guzzlehttp/guzzle": "^6.0",
       "psr/http-message": "^1.0",
       "psr/log": "^1.0"
   }</code>

2. Locate Dependencies on Packagist: Visit the Packagist website and search for each dependency. For each dependency found, repeat this process to identify any further dependencies.
3. Download and Install Base Package: Once all dependencies have been identified, download the base package directly from its GitHub repository or packagist.org.
4. Download and Install Dependencies: Download and install each dependency from its respective source. In most cases, you can simply drop the files into your project directory.
5. Configure Autoloading: Since Composer's autoloader is not being used, you'll need to configure your own autoloader. Refer to the composer.json file to identify the namespace and directory of the base package and dependencies.
6. Create Custom Autoloader: Based on the information gathered, create a custom autoloader function that maps the namespaces to the appropriate directories.

Additional Considerations:

• Composer offers an official GUI installer for Windows and a command-line installation procedure for other platforms, eliminating the need for SSH.
• Composer can be run locally and its output uploaded to your server, eliminating the need for third-party services.
• Packagist.org generates the necessary installation command for each package, simplifying the installation process.

While Composer provides a simple and robust solution for package management, direct installation may be necessary in specific scenarios. By following these steps, you can manually install Composer packages without using Composer.
