Get users yahoo email

Question

I think this yahoo email of users is little problem with yahoo and twitter.

I have searched many days for this but no luck.

Im getting user details like that

  print( $profile->location) ;   --------got location
  print( $profile->gender) ;   --------- got gender

But when i want to get the email i couldnt .

Have tried this

  print( $profile->emails->handle) ;

But i got this error

Notice: Trying to get property of non-object in mywebsite/index.php on line 103

Have tried this

 print( $profile->emails['handle']) ; -----no luck

I have seen this but it seems there are many emails .

How can i get the main email ?

Thanks

EDIT:

i have tryed this

  foreach($profile->emails as $k){
      echo 'handle: ' . $k->handle . '       -----> i got error here 'Undefined property: stdClass::$handle'
            id: ' . $k->id . '               -----> i got the id (no error)
            type: ' . $k->type . '<br>';     -----> i got the type (no error)
  }

i dont know why handle returns error always . is something wrong with handle ?

EDIT2:

i have made this:

  var_dump($profile);

and it gives this
