Mp3 convert minutes into milliseconds
<p>I'm making a websites with some audiofiles. 
So now I'm a bit stuck. 
I have to create a formula that converts f.ex; 3:11 into milliseconds. 
Should I use a while loop to do that?</p>

<pre><code>&lt;category id="cat2"/&gt;
            &lt;thumbnail url="admin/imgsupl/&lt;? echo $row["thumbnail"]; ?&gt;" /&gt;
            &lt;pdf url="admin/docsupl/&lt;? echo $row["filedownload"]; ?&gt;" /&gt;
            &lt;video url="admin/docsupl/alixir.flv" title="Alixir video"/&gt;
            &lt;?
            $ThisFileInfo = $getID3-&gt;analyze("../admin/docsupl/".$row["voice_over_mp3"]);
            getid3_lib::CopyTagsToComments($ThisFileInfo);
            $ThisFileInfo['playtime_string']; //3:11

            ?&gt;
</code></pre>

<p>I can't manage to find an exact formula as well... </p>

<p>Thanks</p>
