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.

What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
