How can I access Microsoft-graph-api with access token in PHP?

To access Microsoft Graph API using an access token in PHP, you need to use a library that supports making HTTP requests and handling OAuth2 authentication. One popular library for this purpose is "GuzzleHttp". Here's a step-by-step guide on how to use it:

1. Install GuzzleHttp using Composer:

First, you need to install GuzzleHttp using Composer, which is a dependency management tool for PHP. If you don't have Composer installed, download it from https://getcomposer.org/ and follow the installation instructions.

Once you have Composer installed, open a terminal or command prompt and run the following command to install GuzzleHttp:

composer require guzzlehttp/guzzle

2. Create a new PHP file:

Create a new PHP file, for example, msgraph.php, and include the GuzzleHttp library at the beginning of the file:

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

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;

3. Define your access token:

Replace <access_token> with your actual access token:

$accessToken = "<access_token>";

4. Create a GuzzleHttp client:

Create a new instance of the GuzzleHttp client and set the default headers, including the access token:

$client = new Client([
    'base_uri' => 'https://graph.microsoft.com/v1.0/',
    'headers' => [
        'Authorization' => 'Bearer ' . $accessToken,
        'Content-Type' => 'application/json'
    ]
]);

5. Make API requests:

Now you can use the client to make API requests. For example, to get the user's profile information, use the following code:

try {
    $response = $client->get('me');
    $data = json_decode($response->getBody(), true);
    print_r($data);
} catch (RequestException $e) {
    echo 'Error: ' . $e->getMessage();
}

Replace the print_r($data) line with the code to process the response as needed.

6. Save and run the script:

Save the file and run it using a PHP interpreter, such as the command-line version or a web server like Apache or Nginx. The script should now make a request to the Microsoft Graph API using the provided access token.

Keep in mind that this example is just a starting point, and you may need to modify it to fit your specific use case. For more information on GuzzleHttp and Microsoft Graph API, refer to their respective documentation:
