php-laravelHow do I use the env() function in Laravel with PHP?

The env() function in Laravel is used to retrieve environment variables from the .env file. It is a wrapper around the PHP getenv() function, which retrieves variables from the system environment.

Example

$database_name = env('DB_DATABASE');
echo $database_name;

Output example

my_database

The env() function takes two parameters, the first being the name of the environment variable, and the second being an optional default value to return if the environment variable does not exist.

1. env('DB_DATABASE') - retrieves the value of the DB_DATABASE environment variable from the .env file.
2. env('DB_DATABASE', 'default_value') - retrieves the value of the DB_DATABASE environment variable from the .env file, or returns default_value if the variable does not exist.
