Answer 1

Be sure that you are using Dotenv after loading from vendor/autoload.php.

For example, I was using OpenCart, in which contained a file startup.php with:

// Autoloader
if (file_exists(DIR_VENDOR . 'autoload.php')) {
    require_once(DIR_VENDOR . 'autoload.php');
}

And I had defined DIR_VENDOR in config.php as:

define('DIR_VENDOR', __DIR__.'/vendor/');

So finally, in index.php, I would have:

// Startup
require_once(DIR_SYSTEM . 'startup.php');

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

So startup.php loads vendor/autoload.php, which loads vlucas/phpdotenv, after which we can then find Dotenv\Dotenv.

just remove/delete the vendor folder and reinstall with the -> composer install.

Answer 3

with "vlucas/phpdotenv": "^5.4" it now works like this:

<?php
require 'vendor/autoload.php';

use Dotenv\Dotenv;

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

or

<?php
require 'vendor/autoload.php';

$dotenv = Dotenv\Dotenv::createImmutable(__DIR__); //Notice the Namespace and Class
$dotenv->load();

Answer 4

check if you have "vlucas/phpdotenv" : "~2.2" in "require" tag in composer file. if you don't then add that plugin and open your terminal and run "composer dump-autoload" then run "composer update". and just to be safe run "composer dump-autoload" once again to refresh all the file paths.

and, if you do have phpdotenv plugin then add that plugin in "require" then just run the dump-autoload command.

I'm having same problem. Here is composer file. { "name": "auth0/basic-webapp-sample", "description": "Basic sample for securing a WebApp with Auth0", "require": { "vlucas/phpdotenv": "2.4.0", "auth0/auth0-php": "~5.0" }, "license": "MIT", "authors": [ { "name": "Martin Gontovnikas", "email": "[email protected]" }, { "name": "Germán Lena", "email": "[email protected]" } ] } Don't know how to fix it. – Pathogenesis

Answer 5

You just need to remove complied.php from bootstrap\cache and it will works fine.

Answer 6

For me worked this code:

use Dotenv\Dotenv;

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

$dotenv = new Dotenv(__DIR__ . "/..");
$dotenv->load();

Instead of this:

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

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

Answer 7

I'm using the PhpStorm IDE and I installed dotenv on the server via SSH. Subsequently I didn't have the new vendor files in the local directory which caused this error. I simply downloaded the up-to-date vendor folder from the server (overwriting the local one) and the error went away.

Answer 11

What helped me:

1. Delete vendor folder fully;
2. Delete vlucas/phpdotenv library from a composer.json;
3. Delete composer.lock itself;
4. Run composer install to initiate again vendor folder and composer.lock file;
5. Run composer require vlucas/phpdotenv again to download the library.

It may still say Undefined type 'Dotenv\Dotenv'.intelephense(1009) on your code editor but on your localhost your project should load without an error. Hope it helps!

Answer 12

Make sure your path to autoload.php is correct '../vendor/autoload.php';
