Php Function, to extract link from short text
<p>I am looking fo a function, to extract the mp3 source of this snippet of code:
<code>http://www.xyz.com/previews/speed_racer_preview.mp3 1930510 audio/mpeg</code></p>

<p>i only need that part:
<code>http://www.xyz.com/previews/speed_racer_preview.mp3</code></p>

<p>This part always has the same structure, only the source changes.</p>
