PHP Environment Variables with PHP Environment Variables Setting up the Project and Package

Error outputting echo getenv('SECRET');

Following to the letter, instructions in the video to output "echo getenv('SECRET');", i am unable to resolve the following error:

Catchable fatal error: Argument 1 passed to Dotenv\Dotenv::__construct() must be an instance of Dotenv\Loader, string given, called in C:\xampp\htdocs\project\inc\bootstrap.php on line 3 and defined in C:\xampp\htdocs\project\vendor\vlucas\phpdotenv\src\Dotenv.php on line 31

Hope i can be pointed to what i'm missing here, thanks.

Finally found the answer. As per documentation on latest upgrade from V2: "you will need to replace any occurrences of 'new Dotenv(...)' with 'Dotenv::create(...)'". Hope it helps another.

require DIR . '/../vendor/autoload.php';

//$dotenv = new Dotenv\Dotenv(DIR); //Old version

$dotenv = Dotenv\Dotenv::create(DIR); //New version as of date

$dotenv->load();

P.S. For reasons unknown, in this answer, the DIR keyword has been stripped of its double underscores(_ _) on both sides. It should be formatted accordingly.

I couldn't get this to work with ::create but it works with ::createImmutable

$dotenv = Dotenv\Dotenv::createImmutable(DIR); $dotenv->load();

The package probably got updated again. the current usage as of July 2020 is

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__);
$dotenv->load();

make sure to check documentaion

If anyone is having trouble echo'ing out the SECRET environment variable, change Dotenv::createImmutable in the bootstrap file to Dotenv::createUnsafeImmutable

Found Here under "Putenv and Getenv" section: https://github.com/vlucas/phpdotenv#:~:text=PHP%20dotenv%20is%20a%20PHP,version%20of%20the%20original%20Ruby%20dotenv.

that basically means it needs to be an instance of the Dotenv\Loader class, so the variable you are sending into the getenv(); needs to be an object that uses the Dotenv\Loader class.

Thank you jamesjones21. The variable in getenv(); comes from a .env file, which is explicitly called by the Dotenv\Dotenv class as per video instruction. However, nothing i have tried so far works, and i see phpdotenv has been updated since that video. I am not a code monkey, and this is not what i will pay for. Would have loved that the video instructions were updated to reflect current implementations. If you will, I'm sure you can replicate the issue if you follow the video. Thanks again.
