php-laravelHow do I get an environment variable in Laravel using PHP?

You can get an environment variable in Laravel using PHP by using the env() helper function. This function takes two parameters, the first being the name of the environment variable, and the second being a default value to return if the environment variable does not exist.

For example:

$database_name = env('DB_DATABASE', 'default_database');

The above code will first look for the DB_DATABASE environment variable. If it exists, the value of that environment variable will be assigned to $database_name. If it does not exist, then default_database will be assigned to $database_name.

Parts of the Code

1. env(): The helper function used to get the environment variable.
2. DB_DATABASE: The name of the environment variable being looked for.
3. default_database: The default value to be returned if the environment variable does not exist.
