Parses .env files to make environment variables accessible in PHP applications via $_SERVER or $_ENV.
Symfony Dotenv is a PHP library that parses `.env` files to load environment variables into PHP applications. It solves the problem of managing configuration across different environments by allowing developers to store environment-specific settings in files rather than hardcoding them or relying on server-level configurations.
PHP developers using Symfony or other PHP frameworks who need a standardized way to manage environment variables and application configuration across development, staging, and production environments.
Developers choose Symfony Dotenv because it integrates seamlessly with Symfony projects, provides a simple and consistent API for loading environment variables, and follows established patterns for environment configuration without requiring external dependencies.
Registers environment variables from a .env file

Integrates natively with Symfony applications, leveraging the framework's configuration system and following its component standards for consistency.
Can load several .env files sequentially, as shown in the README with examples like loading .env and .env.dev, enabling flexible environment-specific overrides.
The loadEnv method automatically loads .env.local and environment-specific files based on APP_ENV, simplifying configuration for different development stages.
Provides an overload() method to optionally overwrite existing environment variables, useful for testing or debugging scenarios.
Only parses .env files and does not support loading environment variables from other sources like databases or cloud services without custom extensions.
As part of the Symfony component suite, it may introduce unnecessary complexity or versioning constraints for standalone PHP projects compared to lighter alternatives.
Lacks features for validating, sanitizing, or type-casting environment variable values, requiring additional manual checks in application code.
