stopping php & keeping php alive

[Dan99]

Hi,

First of all, I am looking for a way to force the execution of a php
script to explicitly stop when told to do so by the client
connection. I know when you hit the browser stop button php normally
stops, but it doesn't stop immediately (ie. if the script is in a
loop, it will keep going for a bit). Also, I am looking for a way to
force php to stay alive, even if the connection to the client drops.
Finally, does anyone know of a way to enable chatter between a single
php script and its client (ie. php well send out something, then the
client will respond, and then php will send another something, ...)

Thanks,
Daniel

Use ignore_user_abo rt():

<http://www.php.net/ignore_user_abo rt>

That will definitely answer your second question. I'm not sure if
there's much you can do about the first one, though. You might try
checking inside the loop if the connection has been aborted and then
breaking out of it.

In a HTML context, spaces are no content, and if you have no buffering
mechanism somewhere, a simple statement like this in every loop:
echo ' ';
flush();
if(connection_a borted()) exit;

....could very well halt execution sooner. However, if you need to stop
'dead on', HTTP is not the way to go.
