如何在另一个php页面上使用选定的链接值

Question

I'm new with questions and generally with "Stack Overflow", so forgive me if it is not formatted well.

So, I have problem with transferring some informations from one page to another. It is a value of <a> tag from an php while loop.

At the moment I have something like this:

$query = mysql_query("SELECT DISTINCT `a`.`id`,`o`.`first_name` , `o`.`last_name` , `a`.`name` FROM `owner` AS `o` , `animal` AS `a` WHERE `o`.`id` = `a`.`fk_current_owner` AND `o`.`fk_user` = '".$_SESSION['user_id']."'");

while($row = mysql_fetch_assoc($query)){
    $pet_id = $row['id'];
    $first_name = $row['first_name'];
    $last_name = $row['last_name'];
    $pet_name = $row['name'];


    echo 'Owner: <strong>'.$first_name.' '.$last_name.'</strong> ';
    echo 'Pet: <strong><a href="viewPet.php" id="'.$pet_id.'">'.$pet_name.'</a></strong><br>';
}

So you can assume that this will display names of pets that logged user got. So I linked their names and I need to get ID of selected name on another page so I can display details of pet on page viewPet.php.

You can also send the pet id along as a GET parameter with the link.

echo '<a href="viewPet.php?id='.$pet_id.'" id="'.$pet_id.'">'.$pet_name.'</a>';

On the viewPet.php page you'd access it by $_GET['id']
