Dotenv\Dotenv::__construct() is not instance of Dotenv\Loader

Question

I am trying to build a Linkedin API code where I am finding a strange error

Fatal error: Uncaught TypeError: Argument 1 passed to Dotenv\Dotenv::__construct() must be an instance of Dotenv\Loader, string given, called in E:\xampp\htdocs\linkedinpi\examples\index.php on line 16 and defined in E:\xampp\htdocs\linkedinpi\vendor\vlucas\phpdotenv\src\Dotenv.php:31 Stack trace: #0 E:\xampp\htdocs\linkedinpi\examples\index.php(16): Dotenv\Dotenv->__construct('E:\\xampp\\htdocs...') #1 {main} thrown in E:\xampp\htdocs\linkedinpi\vendor\vlucas\phpdotenv\src\Dotenv.php on line 31

Which I am unable to replicate how to solve the issue.

I have followed the steps for

https://github.com/zoonman/linkedin-api-php-client and https://github.com/zoonman/linkedin-api-php-client/tree/master/examples

I already downloaded the Vendor by Composer and here is the code I have used

include_once dirname(__DIR__) . DIRECTORY_SEPARATOR . 'vendor/autoload.php';


    use LinkedIn\Client;
    use LinkedIn\Scope;


    $dotenv = new Dotenv\Dotenv(dirname(__DIR__));
    $dotenv->load();

    session_start();

    $client = new Client(
        getenv('[LINKEDIN CLIENT ID]'),
        getenv('[LINKEDIN CLIENT SECRET]')
    );


    if (isset($_GET['code'])) { // we are returning back from LinkedIn with the code
        if (isset($_GET['state']) &&  // and state parameter in place
            isset($_SESSION['state']) && // and we have have stored state
            $_GET['state'] === $_SESSION['state'] // and it is our request
        ) {
            try {
                // you have to set initially used redirect url to be able
                // to retrieve access token
                $client->setRedirectUrl($_SESSION['redirect_url']);
                // retrieve access token using code provided by LinkedIn
                $accessToken = $client->getAccessToken($_GET['code']);
                h1('Access token');
                pp($accessToken); // print the access token content
                h1('Profile');
                // perform api call to get profile information
                $profile = $client->get(
                    'people/~:(id,email-address,first-name,last-name)'

            $filename = './demo.jpg';
            $client->setApiRoot('https://api.linkedin.com/');
            $mp = $client->upload($filename);
            */
        } catch (\LinkedIn\Exception $exception) {
            // in case of failure, provide with details
            pp($exception);
            pp($_SESSION);
        }
        echo '<a href="/">Start over</a>';
    } else {

        pp($_GET);
        pp($_SESSION);

    }

} elseif (isset($_GET['error'])) {

    pp($_GET);
    echo '<a href="/">Start over</a>';
} else {
    // define desired list of scopes
    $scopes = [
        Scope::READ_BASIC_PROFILE,
        Scope::READ_EMAIL_ADDRESS,
        Scope::MANAGE_COMPANY,
        Scope::SHARING,

    $loginUrl = $client->getLoginUrl($scopes);

function pp($anything)
{
    echo '<pre>' . print_r($anything, true) . '</pre>';
}


function h1($h) {
    echo '<h1>' . $h . '</h1>';
}

The error message is pretty self explanatory. Showing the code around this would be helpful. — Jonnix, Aug 01 '19 at 10:45
Sorry I couldn't add code when I posted the question. So now I added the code. — Hritam, Aug 01 '19 at 10:50
`dirname(__DIR__)` is a string. The first param should be an instance of `Dotenv\Loader` as the error says — Jonnix, Aug 01 '19 at 10:57
Have a read of the [docs](https://github.com/vlucas/phpdotenv). They show a static `create` method that does let you just pass a dir path. — Jonnix, Aug 01 '19 at 10:58

changes to invoke Dotenv class custom env -->used to run multiple envs

Git link for the package :Git link for the package

 $dotenv = Dotenv\Dotenv::create(dirname(__DIR__), 'custom env');
 $dotenv->load();

Was facing this issue when i was migrating from laravel 5.8 to laravel 6
note please add help package as the support is remove from core files in laravel 6

if you are using 4.1...

Mutable init

$dotenv = Dotenv\Dotenv::createMutable(__DIR__, $evn_file);
$dotenv->load();

Immutable init

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

Not sure if this is in the same arena (PHP is not my forte) but I found this one liner over at CraftCMS and it's worked very well for me:

Dotenv\Dotenv::createUnsafeMutable(ENV_PATH)->safeLoad();

Kind of hoping that if there is an issue with this I will Cunningham's Law my way into a correct answer. – tfantina Feb 27 '23 at 22:48
