Embed youtube Url

My site allows users to store Youtube url in my database table eg.
http://www.youtube.com/watch?v=-S50SrP1zag&feature=rec-LGOUT-exp_fresh+div-1r-9-HM

How to convert it to embed code format to display as like in community sites like Orkut

 

something like this:

<?php
$youtubeurl= (this comes from your db);
$width=(set the video width);
$height=(set the video height);
?>

<object width="<?php echo $width; ?>" height="<?php echo $height; ?>" data="<?php echo $youtubeurl; ?>" type="application/x-shockwave-flash">
<param name="allowScriptAccess" value="never" />
<param name="allowNetworking" value="internal" />
<param name="wmode" value="transparent" />
<param name="movie" value="<?php echo $youtubeurl; ?>" />
<embed src="<?php echo $youtubeurl; ?>" type="application/x-shockwave-flash" width="<?php echo $width; ?>" height="<?php echo $height; ?>" allowscriptaccess="never" allownetworking="internal" wmode="transparent" />
</object>

If you need to purify user text too, you can take a look at this cool library: http://htmlpurifier.org/

 

Thanks for reply but its not working:
I tried by setting

<?php
$youtubeurl="http://www.youtube.com/watch?v=En4aZkij_q4&feature=rec-LGOUT-exp_fresh+div-1r-5-HM";
$width=200;
$height=200;
?>

<object width="<?php echo $width; ?>" height="<?php echo $height; ?>" data="<?php echo $youtubeurl; ?>" type="application/x-shockwave-flash">
<param name="allowScriptAccess" value="never" />
<param name="allowNetworking" value="internal" />
<param name="wmode" value="transparent" />
<param name="movie" value="<?php echo $youtubeurl; ?>" />
<embed src="<?php echo $youtubeurl; ?>" type="application/x-shockwave-flash" width="<?php echo $width; ?>" height="<?php echo $height; ?>" allowscriptaccess="never" allownetworking="internal" wmode="transparent" />
</object>

 

try to change the url like this:

$youtubeurl="http://www.youtube.com/v/En4aZkij_q4";
