I too am experiencing this problem with Apache 2.2.4 and PHP 5.2.1 on
Ubuntu. Kernel 2.6.
Using a similar script to the one listed above. Connection_status()
returns 0, as does connection_aborted.
However I am streaming video. When streaming this amount of data, the
connection does in fact hang as the image data can't make it to the
client.
I added a shutdown function with register_shutdown_function() to verify
this though. Several minutes after my on-disk log file stops recording
data being sent, the shutdown function writes a message to the same log
file to say that the script has finally been terminated.
So i'm assuming that apache is still trying to send data to the client
even though they're no longer listening and it's the apache
write_timeout that's finally killing the thread.
Because the script is effectively dead in the water while waiting for
data to be received by the client, i can't put in any timeout code to
compensate. So i'm about to try and put a set_time_limit(10) call before
each data transmission so that an output hang is (hopefully) handled
after 10 seconds rather than several minutes.
It would be great though if this was fixed. It would make life so much
easier!

I am having the same problem! I have tried everything. This has not
been fixed since Oct 2004??
This is my code:
<?php
//ob_end_flush();
//This should make it work:
set_time_limit(0);
ignore_user_abort(false);
error_reporting(E_ALL);
ini_set("max_execution_time", "0");
$x = 0;
$error = fopen("file.txt", "a");
echo "Beginning neverending loop";
//Alternate method
register_shutdown_function("help");
while($x < 40)
{
//ob_end_clean();
//ob_start();
$xx = $x."__Connstat: ".connection_status()."Aborted?
".connection_aborted()."\r\n\r\n";
echo $xx;
fwrite($error, $xx, strlen($xx)); //This is written fine.
$x++;
flush(); //If I include this flush, the program stops when I
hit the
stop button. If I don't, it doesn't stop even if I hit the stop button.
sleep(1);
if(connection_status() != 0 || connection_aborted())
{
$msg = "QUIT";
fwrite($error, $msg, strlen($msg));
exit();
}
}
function help()
{
$f = fopen("test.txt", "a");
$m = "QUIT";
fwrite($f, $m, strlen($m));
fclose($f);
exit();
}
?>

Try to do a ob_end_flush(); at the top of your script.

I am having the same problem on SuSE Linux 9.3 running Linux
2.6.11.4-21.9-default, Apache 2.0.53 and PHP 4.3.10 (cli) (built: Aug 31
2005 16:14:46)
The script below can be used to recreate the problem. After I have
press the Stop button (Firefox 1.0.7) the script continues to execute
until it is killed 15 minutes later without the shutdown function being
executed.
<?
function foo() {
exec("echo '".date("Y/m/d H:i:s")." Terminating
Status:".connection_status()."' >> /tmp/test");
}
register_shutdown_function('foo');
exec("echo '".date("Y/m/d H:i:s")." Starting' > /tmp/test");
$count=0;
while (true) {
$count++;
exec("echo '".date("Y/m/d H:i:s")." Running ".$count."
Status:".connection_status()."' >> /tmp/test");
}
?>

I have tried PHP 4.4.0 and 5.0.5 and latest cvs. My server is running
on Windows 2003 with IIS 6. The functions connection_aborted and
connection_status doesn't work properly too.
