Retrieving User Email Address Using Facebook Graph API

Accessing the email address of the currently logged-in user can be a perplexing task when using the Facebook Graph API. Despite the promise of providing basic user information including email address, it's not always straightforward to obtain this data.

To resolve this issue, it's imperative to understand the requirement for extended permissions. The email field falls under this category, meaning you need specific authorization to access it. The user must explicitly grant permission before you can retrieve their email address.

Unfortunately, you cannot gain access to the email addresses of the user's friends. However, you can use Facebook Connect to request extended email permissions by including "scope=email" in the get string of your Auth Dialog call.

To simplify the authentication process and make it more efficient, consider utilizing an SDK instead of the file_get_contents approach. This will greatly assist in handling Oauth authentication.
