How to Install Composer PHP Packages without Using the Composer Tool

If you're trying to install the Coinbase PHP API, which requires Composer, you may be wondering how to do so without utilizing the tool. While Composer is a convenient way to manage PHP dependencies, it may not be necessary in all situations. Here's a manual approach:

1. Identify Package Dependencies:

Examine the composer.json file of the package you want to install (e.g., the Coinbase PHP API). It contains a list of required dependencies.

2. Search for Package Files:

Navigate to the Packagist website and search for the listed dependencies. Download the corresponding package files (e.g., ZIP archives).

3. Repeat for Nested Dependencies:

Check the composer.json files of each dependency you retrieved. Note any nested dependencies and repeat the process of searching and downloading them.

4. Install Packages:

Extract the downloaded package files into a suitable location in your project directory. Ensure they're accessible by PHP's include path.

5. Implement Custom Autoloading:

Since Composer's autoloader won't be used, create a custom autoloader to handle the loading of classes. This information can be obtained from the composer.json files (e.g., PSR-4 autoloading mappings).

6. Manual Require Statements (Optional):

If you don't use a class autoloader, you'll need to determine the individual require_once statements required to include the necessary classes.

Note: Composer offers installation options besides the command line, such as a GUI installer for Windows and remote installation via copying and pasting the installation command from the package website.
