We also have tailored SDKs for Laravel, Symfony, and WordPress. If you are using one of these frameworks, use the tailored SDK for the best integration experience.

Getting Started

Requirements

Please review our support policy for details on our PHP version support.

Installation

Ensure you have the necessary dependencies installed, then add the SDK to your application using Composer:

composer require auth0/auth0-php --no-dev

Configure Auth0

Create a Regular Web Application in the Auth0 Dashboard. Verify that the "Token Endpoint Authentication Method" is set to POST.

Next, configure the callback and logout URLs for your application under the "Application URIs" section of the "Settings" page:

  • Allowed Callback URLs: The URL of your application where Auth0 will redirect to during authentication, e.g., http://localhost:3000/callback.
  • Allowed Logout URLs: The URL of your application where Auth0 will redirect to after user logout, e.g., http://localhost:3000/login.

Note the Domain, Client ID, and Client Secret. These values will be used later.

Add login to your application

Create a SdkConfiguration instance configured with your Auth0 domain and Auth0 application client ID and secret. Generate a sufficiently long, random string for your cookieSecret using openssl rand -hex 32. Create a new Auth0 instance and pass your configuration to it.

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;

$configuration = new SdkConfiguration(
    domain: 'Your Auth0 domain',
    clientId: 'Your Auth0 application client ID',
    clientSecret: 'Your Auth0 application client secret',
    cookieSecret: 'Your generated string',
);

$auth0 = new Auth0($configuration);

Use the getCredentials() method to check if a user is authenticated.

// getCredentials() returns null if the user is not authenticated.
$session = $auth0->getCredentials();

if (null === $session || $session->accessTokenExpired) {
    // Redirect to Auth0 to authenticate the user.
    header('Location: ' . $auth0->login());
    exit;
}

Complete the authentication flow and obtain the tokens by calling exchange():

if (null !== $auth0->getExchangeParameters()) {
    $auth0->exchange();
}

Finally, you can use getCredentials()?->user to retrieve information about our authenticated user:

print_r($auth0->getCredentials()?->user);

That's it! You have successfully authenticated your first user with Auth0! From here, you may want to try following along with one of our quickstarts or browse through our examples for additional insight and guidance.

If you have questions, the Auth0 Community is a fantastic resource to ask questions and get help.
