php-symfonyHow to use the PHP Symfony Dotenv component?

The PHP Symfony Dotenv component is a library that allows developers to store configuration information in environment variables. It is used to keep sensitive information such as passwords and API keys out of source code.

Example code

use Symfony\Component\Dotenv\Dotenv;

$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/.env');

This code will load the environment variables from the .env file in the current directory.

Code explanation

• use Symfony\Component\Dotenv\Dotenv; - imports the Dotenv class
• $dotenv = new Dotenv(); - creates a new instance of the Dotenv class
• $dotenv->load(__DIR__.'/.env'); - loads the environment variables from the .env file in the current directory
