Description

A lightweight PHP library for authenticating and retrieving user data from Microsoft Graph API using OAuth 2.0. This library simplifies the process of obtaining access tokens and fetching user information through Microsoft's authentication system.

Features

• Easy Microsoft OAuth 2.0 authentication
• Token retrieval and management
• Fetch user profile information
• Supports multiple tenants and scopes
• Built with Guzzle HTTP client and Microsoft Graph SDK

Prerequisites

• PHP 7.4+
• Composer
• Microsoft Azure Active Directory application credentials

Installation

Install the library using Composer:

    $client_secret,
    $redirect_uri,
    $tenant_id
);

// Generate authorization URL
$authorizationUrl = $microsoftGraph->get_url_auth();

// Redirect user to authorization URL
header("Location: " . $authorizationUrl);

// After user authorization, exchange code for token and retrieve user data
$userData = $microsoftGraph->get_data($authorizationCode);

if ($userData->valid) {
    // Access user information
    echo "User Name: " . $userData->getDisplayName();
}
