Help Regular Expressions preg_replace

[marcionline]

I have this regexp to post edonkey links that replace this

"#(^|(?<=[^\w\"']))(ed2k://\|file\|([^\\/\|:<>\*\?\"]+?)\|(\d+?)\|([a-f0-9]{32})\|(.*?)/?)(?![\"'])(?=([,\.]*?[\s<\[])|[,\.]*?$)#i"

to this:

<a href='http://www.emugle.com/details.php?f=\\5' target='_blank'><img src='http://www.mistershare.org/home/images/misc/emugle-icon.gif' border='0'></a> <img src='http://www.mistershare.org/home/images/misc/emule.gif' border='0'> <a href='\\2'>\\3&nbsp;<b>($size)</b></a>"

Here an example of edonkey link:

ed2k://|file|[Ubuntu.Linux.6.06].ubuntu-6.06-desktop-i386.iso|731744256|FB73A6DBAEFDFB7969FFD8CE8E4FC6E3|/

This part 731744256 is the size's file in bytes.

So, I would like know if is there a regexp to get this part of link and format to something more human (like 697.85 MB, for example) because the $size in original function only work for me when there arent't anything above the edonkey link.

The original function is this:

//######## INICIO HACK EDONKEY LINKS ########

 $text = ' ' . $text;

 $size = humanize_size(preg_replace("#(^|(?<=[^\w\"']))(ed2k://\|file\|([^\\/\|:<>\*\?\"]+?)\|(\d+?)\|([a-f0-9]{32})\|(.*?)/?)(?![\"'])(?=([,\.]*?[\s<\[])|[,\.]*?$)#i", "\\4", $text));

 $patterns[] = "#(^|(?<=[^\w\"']))(ed2k://\|file\|([^\\/\|:<>\*\?\"]+?)\|(\d+?)\|([a-f0-9]{32})\|(.*?)/?)(?![\"'])(?=([,\.]*?[\s<\[])|[,\.]*?$)#i";
		
 $replacements[] = "<a href='http://www.emugle.com/details.php?f=\\5' target='_blank'><img src='http://www.mistershare.org/home/images/misc/emugle-icon.gif' border='0'></a> <img src='http://www.mistershare.org/home/images/misc/emule.gif' border='0'> <a href='\\2'>\\3&nbsp;<b>($size)</b></a>";

 //######### FIM HACK EDONKEY LINKS ##########

And here is the humanize_size function:

<?php

	function humanize_size ($size, $rounder = 0, $min = '')
{
   $sizes   = array('Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB');
   $rounders = array(0,   1,	2,	2,	2,	3,	3,	3,	3);
   $ext = $sizes[0];
   $rnd = $rounders[0];

   if ($min == 'KB' && $size < 1024)
   {
	  $size = $size / 1024;
	  $ext = 'KB';
	  $rounder = 1;
   }
   else
   {
	  for ($i=1, $cnt=count($sizes); ($i < $cnt && $size >= 1024); $i++)
	  {
		 $size = $size / 1024;
		 $ext  = $sizes[$i];
		 $rnd  = $rounders[$i];
	  }
   }

   if (!$rounder)
   {
	  $rounder = $rnd;
   }

   return round($size, $rounder) . '&nbsp;' . $ext;
}		

?>

Any help would be great.
