Parse swf with PHP header

As I know it is easy to parse simple swf file in php with flash header:

<?php
$filename="xxx.swf";
header("Content-Type: application/x-shockwave-flash");
@readfile($filename);
?>

Code (markup):

or

<?php
$filename = "xxx.swf";
$fh = fopen($filename,"r");
header("Content-type: application/x-shockwave-flash");
fpassthru($fh);
?>

Code (markup):

But I'm not able to force any swf file to work with some flashvars, eg.
$filename = "xxx.swf?config=yyy.xml";

Any idea for that? or workaround?

Bumping up. Nobody knows?

youtube use it, metacafe, dailymotion, etc.
Eg.
Within youtube embed code you have movie url:
http://www.youtube.com/v/037uSAIahho
Of course this is not flash file.
It is redirected and outputs correct swf file with lot of flashvars.

How to do such thing?
Will pay for solution or showing right direction how to...

 

try using htaccess!!!

 

Yes I tried, but seems I have too many, nested flashvars, like:

movie.swf?conf=fonfig.php?value=xxx&settings=set.php?value=xxx

As far I found I can parse movie as javascript (also with rewrite method).
The code is very short and generates swf object nested in DIV.
The only minus is that the end user cannot change movie dimensions (or maybe it is plus).
An example of embed movie:

and original:

Still I'm looking for better solution, though what I found now is not so bad
