URL-TRIK: Cara Menyembunyikan Link di BAR WEB

You can use buttons instead of <a> for this purpose:

<button onclick="window.location.href='location.html'">Continue</button>
example for your case

<button class="class" onclick="window.location.href='<?php echo $data['recording_link'];?>'">Play Recording</button>
