connection handling in PHP and ignore_user_abort() question !

[quecoder]

There is something that I don't clearly understand ..
when I run this script :

<?php
sleep(30);
$fp = fopen('file.txt','w+');
?>

and close the browser instantly ( before the 30 seconds run out of the sleep function ) .. I wait about 30 seconds and I find that file.txt has been created successfully .. although , I have not used ignore_user_abort(ture) ..and the manual states : If you do not tell PHP to ignore a user abort and the user aborts, your script will terminate. at : http://www.php.net/manual/en/features.connection-handling.php

I can not understand what they mean at this page completely .. only experts can comprehend it ... any idea about the first issue and about where can I learn more about connection handling in PHP in an easy way ?

Try pressing the "stop" button 😉 Closing the browser doesn't send the RST packets probably. As quoted from the manual comments:

If user STOPS, script ignores the RST and runs to completion (the output is apparently ignored by apache and not sent to the user, who sent the RST and closed the TCP connection). If user's connection just vanishes (isp problem, disconnect, whatever), and there is no RST sent by user, then eventually the script will timeout.
