PHP Readfile() number of bytes when user aborted - php

Question

I'm using a PHP script to stream a live video (i.e. a file which never ends) from a remote source. The output is viewed in VLC, not a web browser. I need to keep a count of the number of bytes transferred. Here is my code:
<?php
ignore_user_abort(true);
$stream = $_GET['stream'];
if($stream == "vid1")
{
$count = readfile('http://127.0.0.1:8080/');
logThis($count);
}
function logThis($c)
{
$myFile = "bytecount.txt";
$handle = fopen($myFile,'a');
fwrite($handle,"Count: " . $c . "\n");
fclose($handle);
}
?>
However it appears that when the user presses the stop button, logThis() is never called, even though I've put in ignore_user_abort(true);
Any ideas on what I'm doing wrong?
Thanks
Update2: I've changed my code as I shoudn't be using ignore_user_abort(true) as that would continue to download the file forever even after the client has gone. I've changed my code to this:
<?php
$count = 0;
function bye()
{
//Create Dummy File with the filename of equal to count
}
register_shutdown_function('bye');
set_time_limit(0);
ignore_user_abort(false);
$stream = $_GET['stream'];
if($stream == "vid1")
{
$GLOBALS['count'] = readfile('http://127.0.0.1:8080/');
exit();
}
?>
My problem now is that when the script is aborted (i.e. user presses stop), readfile won't return a value (i.e. count remains at 0). Any ideas on how I can fix this?
Thanks

Answer 1

When a PHP script is running normally the NORMAL state, is active. If the remote client disconnects the ABORTED state flag is turned on. A remote client disconnect is usually caused by the user hitting his STOP button. If the PHP-imposed time limit (see set_time_limit()) is hit, the TIMEOUT state flag is turned on.
so setting the set_time_limit to 0 should help.

Ok folks I managed to fix this. The trick was to not use readfile() but read the video stream byte by byte. Ok it may not be 100% accurate, however a few bytes inaccuracy here or there is ok.
<?php
$count = 0;
function logCount()
{
//Write out dummy file with a filename equal to count
}
register_shutdown_function('logCount');
set_time_limit(0);
ignore_user_abort(false);
$stream = $_GET['stream'];
if($stream == "vid1")
{
$filename = 'http://127.0.0.1:8080/';
$f = fopen($filename, "rb");
while($chunk = fread($f, 1024)) {
echo $chunk;
flush();
if(!connection_aborted()) {
$GLOBALS['count'] += strlen($chunk);
}
else {
exit();
}
}
}
?>
