How to comment HTML code that has PHP in it?

I have HTML code that has PHP in it, and I wanted to comment on it.

<input type="hidden" name="returnurl" value="<?php if (!empty($link)) {echo $link;}?>">

How to comment both HTML and PHP separately without comments?

Thanks to Ross Patterson, I found that I did not completely understand this question. So here is the new answer. I leave the old answer below, as it may be useful for some people.

You can handle it easily, as there are no PHP lines or comments in your code. This means that commenting on this piece of code is as simple as:

<?php
/*
<input type="hidden" name="returnurl" value="<?php if (!empty($link)) {echo $link;}?>">
*/
?>

, , , . :

<div>
  You're logged in.
  <?php
  /**
   * Says "hello" to the person.
   * @param string $name The name of the person.
   */
  function SayHello($name)
  {
    echo 'Hello, ' . $name;
  }

  SayHello($personName);
  ?>
</div>
