PHP Quick Question

Well the best way to help explain is by giving you first the example
http://g4hq.com/rssbasic.php

The php code

<?php
$youtube = "http://s1.ytimg.com/vi/";
$link = "[youtube]";
$youtubex = "/default.jpg";
$linkx = "[/youtube]";
$larry = "http://youtube.com/rss/global/top_viewed_today.rss";
$fp = file_get_contents($larry);
$newfp = str_replace($youtube, $link, $fp);
$nex = str_replace($youtubex, $linkx, $newfp);
$flex = trim($nex,"&lt;img");
echo "$flex";
?>

PHP:

Now
View the source on that page above .. and the problem is i get this ->

I want to remove the <img src=" and possibly the align="right".../> Parts
so it would be [youtube]XXXXX[/youtube]

How would i go upon doing so? I tried to trim <img src.. and that didnt work -_-



I want it so that it is removes <img src="[youtube]lklfIPBK4Zg[/youtube]" align="right" border="0" width="120" height="90" vspace="4" hspace="4" />

 

I think something may be wrong anyway. The first item is shown as <img src="[youtube]blah[/youtube]">

Here's what the others look like;
<img src="http://s3.ytimg.com/vi/jdzCxvbe5Hg[/youtube]

If you fix this I can do this easily

 

well yeah i can fix that
tho how would i remove the <img src ?

 

I fixed the part aforementioned, am working on removing the img src right now.

 

ight thanks
