Variable in PHP http link
<p>I'm trying to get the cureent url and send that through in a link and I'm stuck. The link displays but it's missing the url that I want to include (content in the code sample here)</p>

<pre><code>'href' =&gt; ( "http://chart.apis.google.com/chart?cht=qr&amp;chs=300x300&amp;choe=UTF-8&amp;chld=H&amp;chl='.$content .'")
</code></pre>
