I changed the code slightly since I posted the original post of this
thread. You can see my modified code below. I'm still having the same
problem. IE will download the file and then trigger my music player to
play it, which is not a terrible outcome, though it would be nice if IE
would play this file in-browser, like it does when I point IE directly
at the MP3 file. FireFox is worse: it'll play the first second of the
song and then stop. I suspect I'm missing some header somewhere, but I
can't figure out which one. User-Agent, perhaps?

$fileToPlay = "Enemy.mp3";
$allBytesInFile = filesize($fileToPlay);
$tenPercentOfFileInBytes = $allBytesInFile * .1;
$tenPercentOfFileInBytes = round($tenPercentOfFileInBytes );
// 09-02-06 - this next line is giving me 282548, which is correct, I
think.
// That's how many bytes we want to share with the public.
//echo $tenPercentOfFileInBytes;
$streamToOpen = "www.monkeyclaus.org";
$port = "80";
$path = "/$fileToPlay";
header("Content-type: audio/mpeg");
$socket = fsockopen($streamToOpen,$port);
fputs($socket, "GET $path HTTP/1.0\r\n");
fputs($socket, "Host: $streamToOpen\r\n");
fputs($socket, "Accept: */*\r\n");
fputs($socket, "Connection: close\r\n\r\n");
// while (!feof($socket)) {
// $buffer = fgets($socket, 4096);
// echo $buffer;
// }
$totalSize = 0;
for ($i=0; $i < $tenPercentOfFileInBytes; ) {
$buffer = fgets($socket);
$strSize = strlen($buffer);
$totalSize = $totalSize + $strSize;
// echo "$strSize \n";
$i = $i + $strSize;
echo $buffer;
}
fclose($socket);
