Accessing User Email Addresses through Facebook Graph API

The Facebook Graph API provides comprehensive access to user data, including personal information like email addresses. To retrieve a user's email address, a few steps are required:

Requesting Extended Permissions

Unlike other user information, accessing email addresses necessitates requesting extended permissions. Visit the Facebook Developers documentation on permissions for further details.

Using an SDK for Authentication

Utilizing an SDK simplifies the OAuth authentication process, making it more efficient and secure.

Code Example

Here's an example code snippet that incorporates the necessary extended permission:

$facebook->getLoginURL(array(
    'scope' => 'email', // Request email permission
));

Note:

It's important to remember that users must grant permission to access their email addresses. You cannot automatically retrieve friend's email addresses using this method.
