php中的个人资料页面，结果不同

Question

The following piece of code displays my name if I see my profile page. I want to modify it, so that if I will visit the profile page of another user, his profile page to displays both name and email.

<?php

if(  isset($_GET['email']) === true  &&  empty($_GET['email']) === false  ){

  $email    = $_GET['email'];

  if(user_exists($email) === true) {

    $user_id = user_id_from_email($email); 

    $profile_data   = user_data($user_id,'name','email');

    echo $profile_data['name'];
?>

if(  $session_user_id !== $user_id ){echo $profile_data['email'];}
