If you try to do plain text, you should ignore the context-type in this block

 $headers = array(
        'Authorization: key=12dsdsvefdfdfgdfgdfgdfgfgfgfg',
        'Content-Type: application/x-www-form-urlencoded'
    );

Also, you should use for plain text the registration ID is passed in a parameter called registration_id instead of registration_ids array.
