Loading FLV via PHP

Question

Gang,
I've been unable to find any solution - or even a solid
explanation - for this problem anywhere.
I've built a custom FLV player that needs to rely on a PHP
script to serve it FLV files in order to control access to those
files. My player uses the FLVPlayback component.
My actionscript makes a call like this to the PHP script:
my_player.contentPath = "resource.php?id=12345"
I've also tried...
my_player.load("resource.php?id=12345");
The resource.php code in question looks something like this:
header('Content-Type: video/x-flv');
readfile("my_video.flv");
When tested, the FLVPlayback component simply won't accept
the FLV served up to it in this way. It WILL work if loading
directly from the file system, so I know my actionscript works. I
can load just about any other type of file into Flash this way,
including JPG and SWF. FLV is the only format that doesn't work.
I've added the video/x-flv MIME Type to all test servers I've
tried this on, so the server should recognize the file.
So here's the question: How can I get my PHP script to serve
the FLV to my FLVPlayback-based player?
Thanks,
J

Solved!
The root cause was that the FLV served up by the PHP script
was being sent to Flash with a .php file extension, which the
FLVPlayback component doesn't seem to like. The root solution,
therefore, was to rename the PHP script with a .flv exension, as
outlined below.
The files in the "resources/" folder:
resources/
-- .htaccess
-- test.xxx (a renamed FLV file)
-- resource.flv (a renamed PHP script)
The .htaccess file:
AddType application/x-httpd-php .flv
The PHP script (renamed to "resource.flv"):
$filename = "test.xxx";
header('Content-Type: video/x-flv');
header('Length: ' . filesize($filename));
header('Content-Disposition: attachment;
filename="'.$filename.'"');
$fd = fopen($filename, "r");
while(!feof($fd)) {
echo fread($fd, filesize($filename));
flush();
fclose ($fd);
The salient ActionScript:
//my FLVPlayback compontent instance is named "video"
video.load("[server]/resources/resource.flv");
There may be some extraneous headers in the PHP script, but
at least it works.
