How to Install PHP Packages Without Using Composer?

Installing PHP Packages Without Composer

Despite its prevalence, Composer remains an optional tool for installing PHP packages. For those seeking an alternative method, consider the following approach:

Identifying Package Dependencies

Begin by examining the composer.json file associated with the desired package. This file lists the dependencies it requires. For instance, the Coinbase PHP API depends on the following:

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

Finding Dependency Packages

Proceed to the Packagist website (packagist.org) to search for each dependency package. Explore their composer.json files to identify any further dependencies and search for them recursively.

Compiling Required Packages

Once all required packages are identified, download and place them in your project directory. However, ensure that PHP can locate these class files by adding them to your custom autoloader.

Autoloader Configuration

Refer to the composer.json file to determine the autoload mapping. For example:

<code class="json">"autoload": {
    "psr-4": { "Coinbase\Wallet\": "src/" }
},</code>

Configure your autoloader with this information or determine the individual require_once statements directly from the composer.json files.

Alternative Solutions

Despite the detailed process, Composer remains the recommended choice for managing dependencies due to its simplicity and flexibility. However, other options exist:

• Install a library and develop a custom download script based on it.
• Utilize online Composer interfaces to avoid installing Composer locally.

These alternatives may not fully address the specific concerns raised about Composer, including its learning curve, third-party involvement, and dependency tree complexity.
