Application Configuration using PHP Environment Variables

Mauro Chojrin's article discusses the importance of securely storing sensitive information, such as database credentials and API keys, in web applications. He explains that hardcoding these values directly into code is not recommended due to its limitations and potential security risks. Instead, he suggests using external files, environment variables, or a secrets manager like Doppler to store and manage sensitive data. The article covers various ways to implement this approach, including using .env files, Docker, and custom PHP configurations. It also provides sample code and examples for different scenarios, including Laravel applications and integrating with tools like Laravel Forge. Overall, the article aims to provide a comprehensive overview of the best practices for securely storing secrets in web applications.
