If you have used Laravel and gotten used to being able to set and switch between environments as easily as swapping out a .env file.
Using mykehowells/dotenv, you can now add that functionality to your own projects with composer.
Add mykehowells/dotenv to your project via composer with the following line:
composer require mykehowells/dotenv
Add the below code to check for a .env file, and import if it exists. Preferably, you should store this file outside of any publicly accessible directories, as it will contain potentially sensitive data - such as database credentials.
Check out the vlucas/phpdotenv readme for more info on that package.
/*----------------------------------------------------------------------------
| ENV CONFIGURATION
|-----------------------------------------------------------------------------
|
| Check to see if an env file exists at project root, if it does, import
| keys and values into putenv( $setting ), otherwise env( $key, $default=null )
| will return default value.
|
|---------------------------------------------------------------------------*/
load_env( __DIR__ );You can then start using the env( $key, $default = null ) function to retrieve data from your .env file.
