Removing link tags and inner html,& alphanumeric characters except twitter @username from generated content
<p>I am using the following <strong>*echo preg_replace('#.<em>?\s</em>(.<em>)#', "$1", $playlist->description)</em></strong> to display a block of content in my template. </p>

<p>The result is showing "blah blah blah (@twitter)" and I would like to take this a step further, reducing to twitter name only without "<strong>()</strong>" leaving "<strong>,</strong>" and "<strong>&amp;</strong>" in the content that is generated.</p>

<p>My goal is to show only twitter user names ie "<strong>@twitter</strong>" while leaving out other text, links &amp; special characters. </p>

<p>An example of the default generated content using <strong>"echo $playlist->description"</strong> displays as follows: "<a href="http://google.com" rel="nofollow">http://google.com</a> Blah Blah Blah (@twitter)"</p>

<p>I am looking to achieve the following result:
"@twitter"</p>

<p>I'm a self proclaimed php noob, and I feel like I'm in a little over my head here, but I'm dedicated to achieving my result. Any assistance is greatly appreciated.</p>

<p>Cheers,
Mike</p>
