How I can navigate to another page and display user data?

Question

I know how to fetch user data from database with the code below. Now I want to navigate to another page (using onclick) and to display this user data by id. This would be like StackOverflow or Facebook, when you click on a photo or ID, and the site takes you to the user's profile page.

Here is my code so far:

  <?php
   $connect = mysql_connect("localhost","root","") or die(mysql_error());
   $select = mysql_select_db("profile") or die(mysql_error());
   $result = mysql_query("SELECT * FROM users order by id DESC");
   $id = $_SESSION['id'];

    while($row = mysql_fetch_array($result)){
        if($row['id'] !== $id){
             echo "<table id='suggest'><tr><td id='frienddata'><a href='http://localhost/profile/userprofile.php'>".$row['first'].' '. $row['last']."<a/></td><br></tr></table>";
        }
    }
?>

Answer 1

 $id = $_GET['id']; if(!isset($id)) { $connect = mysql_connect("localhost","root","") or die(mysql_error()); $select = mysql_select_db("profile") or die(mysql_error()); $result = mysql_query("SELECT * FROM users WHERE id = '"$id"'"); if(!$result) { die('user_not_found'); } mysqli_fetch_row( $result ); echo "<table id='sugest'><tr><td id='frienddata'><a href='http://localhost/profile/userprofile.php'>".$row['first'].' '. $row['last']."<a/></td><br></tr></table>"; 

Answer 2

suppose you are in a page before clicking on a user profile,the link should be some thing like this 'site.com/userprofile.php?id=5'. now in userprofile.php:

$id = $_GET['id'];
if(!isset($id))
     die('user not found');
$connect = mysql_connect("localhost","root","") or die(mysql_error());
$select = mysql_select_db("profile") or die(mysql_error());
$result = mysql_query("SELECT * FROM users where id='".$id."'");
if (!$result) {
 die('user not found');
}
$row = mysql_fetch_row($result);
echo "<table id='sugest'><tr><td id='frienddata'><a href='http://localhost/profile/userprofile.php'>".$row['first'].' '. $row['last']."<a/></td><br></tr></table>";
