}// API flag, output JSON if set

                     
}

                           
}

                                 
continue;// skip displaying user emails
writeToHtmlPage($fieldName,$fieldValue);
echo json_encode($record);

The programmer is careful to not display the user's e-mail address when displaying the public HTML page. However, the e-mail address is not removed from the JSON response, exposing the user's e-mail address.
