How to Manually Install PHP Packages without Composer?

Installing PHP Packages without Composer

Installing PHP packages through Composer is a recommended practice, but there may be scenarios where using Composer is not possible or desirable. This article provides a step-by-step guide to manually install PHP packages without using Composer.

Identifying the Required Dependencies

The Coinbase PHP API, as mentioned in the question, requires the following composer dependencies:

• php: >=5.5.0
• guzzlehttp/guzzle: ^6.0
• psr/http-message: ^1.0
• psr/log: ^1.0

Retrieving Packages from Packagist

For each dependency, visit packagist.org to locate the corresponding PHP package. Download the latest stable release's archive (usually a zip or tar file).

Installing the Packages

Extract the downloaded package archives into a directory on your server. Ensure the PHP include path is configured to search for classes within these directories. Example:

set_include_path(get_include_path() . PATH_SEPARATOR . '/path/to/packages');

Addressing Autoloading

Instead of using Composer's autoloader, create your own custom autoloader to automatically load classes from the installed packages. Information for autoloading classes can be found in each package's composer.json file under the "autoload" section.

Additional Considerations

• If a dependency has its own dependencies, repeat the installation process for those dependencies as well.
• Ensure that the application configuration matches the package configuration (e.g., loading class aliases).
• Despite the challenges, Composer remains the preferred method for installing PHP packages due to its versatility and community support. Consider utilizing its official installation methods or remote execution capabilities if possible.
