How to display html link element inside php script

Question

I am trying to include a php variable inside this php script that displays an html link. What i need is to include my php $row['vin'] variable in the href html link after the ? to pass a value to the page i am linking to. Top code block works but i still need that php variable, bottom is an example of what ive tried which will not work.

Works but missing my php variable:

 <?php if($row['instock'] == "Yes")
    {
         echo '<a href="orderForm.php?">
         <span class="glyphicon glyphicon-plus" aria-hidden="true">
         </span>
         </a>';
    }
    ?>

Does not work:

<td>
<?php if($row['instock'] == "Yes")
{
      echo '<a href="orderForm.php?'. $row['vin']">
      <span class="glyphicon glyphicon-plus" aria-hidden="true">
      </span>
      </a>';
}
?>
</td>

You've forgotten the rest of the concatenation logic. It's just a syntax error:

<td>
<?php if($row['instock'] == "Yes")
{
      echo '<a href="orderForm.php?'. $row['vin'] . '">
      <span class="glyphicon glyphicon-plus" aria-hidden="true">
      </span>
      </a>';
}
?>

An alternative to using PHP to echo out great chunks of mostly static content is to instead, drop in and out of the PHP context (ie <?php ... ?>) when necessary and use it like a templating language.

For example

<td>
  <?php if ($row['instock'] == "Yes"): ?>
    <a href="orderForm.php?<?= htmlspecialchars($row['vin']) ?>">
      <span class="glyphicon glyphicon-plus" aria-hidden="true"></span>
    </a>
  <?php endif ?>
</td>
