The id attribute is only used client side, so short of using JavaScript to modify the URL — you can't.

Put the data in the URL in the first place … and exercise some safety over adding data to URLs and HTML.

<a href="show.php?ref=<?php 
  echo htmlspecialchars(urlencode($row['name']));
?>&id=<?php 
  echo htmlspecialchars(urlencode($id));
?>" 
id="<?php 
  echo htmlspecialchars($id);
?>"><?php 
  echo htmlspecialchars($id) . '.' . htmlspecialchars($row['name']); 
?></a>

I believe you're looking for $_GET.

<?php

   //show.php?ref=5&id=10

   echo $_GET['ref'];
   //5

   echo $_GET['id'];
   //10

?>

Solution 3:[3]

<?php echo $_GET["id"]; ?>
