The only way to get the users e-mail address is to request extended permissions on the email field   The user must allow you to see this and you cannot get the e-mail addresses of the user s friends   http   developers facebook com docs authentication permissions  You can do this if you are using Facebook connect by passing scope email in the get string of your call to the Auth Dialog   I d recommend using an SDK instead of file get contents as it makes it far easier to perform the Oauth authentication

Assuming you ve requested email permissions when the user logged in from your app and you have a valid token   With the fetch api you can just  const token    some valid token   const response   await fetch           https   graph facebook com me fields email amp access token   token            const result   await response json      result will be          id    some id        email    name example org      id will be returned anyway   You can add to the fields query param more stuff  but you need permissions for them if they are not on the public profile  name is public     fields name email user birthday amp token    https   developers facebook com docs facebook-login permissions

For me the problem with collecting user s email addres on PHP side  getGraphUser   method  was  that the default behavior of facebook-rendered button  on WEBSIDE side  created with xfbml 1  is to implicity calling FB login   with the scope NOT including  email    That means you MUST   1  call     FB login       scope  email      manifestly  creating your own button to start login process  OR   2  add scope  email  attribute to the xfbml button     lt div class  fb-login-button  data-size  large  data-button-type  continue with  data- layout  rounded  data-auto-logout-link  false  data-use-continue-as  true  data- width  1000px  scope  email  gt  lt  div gt     to be able to collect email address on PHP side    Hope it helps

To get the user email  you have to log in the user with his Facebook account using the email permission  Use for that the Facebook PHP SDK  see on github  as following   First check if the user is already logged in    require  facebook php    facebook   new Facebook array       appId     gt  YOUR APP ID       secret    gt  YOUR APP SECRET        user    facebook- gt getUser    if   user        try            user profile    facebook- gt api   me          catch  FacebookApiException  e             user   null            If he his not  you can display the login link asking for the email permission    if    user         args   array  scope    gt   email        echo   lt a href       facebook- gt getLoginUrl        gt Login with Facebook lt  a gt      else       echo   lt a href       facebook- gt getLogoutUrl        gt Logout lt  a gt        When he is logged in the email can be found in the  user profile array   Hope that helps

Make sure your Facebook application is published  In order to receive data for email  public profile and user friends your app must be made available to public    You can disable it later for development purposes and still get email field
