如何将soundcloud url替换为iFrame（PHP）

How can I detect and replace a soundcloud url in a text with an iframe using PHP:

For example:

This:

https://soundcloud.com/aathmigan/eminem-ft-dr-dre-old-time-sake

Into this:

<iframe width="100%" height="166" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/140068709&amp;color=00aabb&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false"></iframe>

  function linkifySoundcloudURLs( $text )
  {
    $text = preg_replace('#https{0,1}:\/\/w{0,3}\.*soundcloud\.com\/([^< ]+)#ix',
    '<iframe width="100%" height="166" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=https://soundcloud.com/$1&amp;color=00aabb&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false"></iframe>',
      $text);
    return $text;
  }

Works for me.

I'm not sure I understand you correctly, but something like this?

<?php
  $url = "https://soundcloud.com/aathmigan/eminem-ft-dr-dre-old-time-sake";
?>    

<iframe width="100%" height="166" scrolling="no" frameborder="no"
    src="<?php echo $url; ?>"></iframe>
