Connecting to Office 365 is the first step every app must take to start working with Office 365 services and data. This sample shows how to connect and then call one API through Microsoft Graph (previously called Office 365 unified API), and uses the Office Fabric UI to create an Office 365 experience.

Try out the Get started with Office 365 APIs page which simplifies registration so you can get this sample running faster.

Note: For an in-depth look at the code, see [Call Microsoft Graph in a PHP app]. (http://graph.microsoft.io/docs/platform/php).

To use the Office 365 PHP Connect sample, you need the following:

• PHP is required to run the sample on a development server. The instructions in this sample use the PHP 5.4 built-in web server. However, the sample has also been tested on Internet Information Services and Apache Server.

  • Client URL (cURL) module. The web application uses cURL to issue requests to REST endpoints.

• An Office 365 account. You can sign up for an Office 365 Developer subscription that includes the resources that you need to start building Office 365 apps.

  Note:
  If you already have a subscription, the previous link sends you to a page with the message Sorry, you can’t add that to your current account. In that case use an account from your current Office 365 subscription.
  
  If you are already signed-in to Office 365, the Sign-in button in the previous link shows the message Sorry, we can't process your request. In that case sign-out from Office 365 in that same page and sign-in again. 1pplications use for authentication and authorization. A trial subscription can be acquired here: Microsoft 2zure.3 Important: <br /4 You also need to make sure your Azure subscription is bound to your Office 365 tenant. To do this, see the Active Directory team's blog post, Creating and Managing Multiple Windows Azure Active Directories. The section Adding a new directory will explain how to do this. You can also see Set up your Office 365 development environment and the section Associate your Office 365 account with Azure AD to create and manage apps for more information.

• A client ID, and key values of an application registered in Azure. This sample application must be granted the Send mail as a user permission for the Microsoft Graph. For details see Register your web server app with the Azure Management Portal and grant proper permissions to the Connect application.

  Note:
  During the app registration process, make sure to specify http://localhost:8000/callback.php as the Sign-on URL.

1. Using your favorite IDE, open Constants.php in the app folder.

2. Replace ENTER_YOUR_CLIENT_ID with the client ID of your registered Azure application.

3. Replace ENTER_YOUR_SECRET with the client secret of your registered Azure application.

4. Start the built-in web server with the following command:

   php -S 0.0.0.0:8000 -t app
   

5. Navigate to http://localhost:8000 in your web browser.

You receive the following error after providing your credentials to the sign in page.

SSL certificate problem: unable to get local issuer certificate

cURL can't verify the validity of the Microsoft certificate when trying to issue a request call to get tokens. You must configure cURL to use a certificate when issuing https requests by following these steps:

1. Download the cacert.pem file from cURL website.

2. Open your php.ini file and add the following line

   curl.cainfo = "path_to_cacert/cacert.pem"
