<p>This code currently grabs actor data from the MYSQL and then prints it out. </p>

<p>Is there a way to edit the below code so that the a href link result is all lowercase letters?</p>

<pre><code>$TMPL['actor'] = '';
    foreach(explode(', ', $TMPL['actors']) as $v)
    $TMPL['actor'] .= '&lt;a href="/actor/'.str_replace("+", "-", urlencode($v)). '"&gt;'.$v.'&lt;/a&gt; &lt;br /&gt;';       
    $actors .= $skin-&gt;make();
</code></pre>
