losing STDIN

[Karstens Rage]

I am using:

PHP 5.0.4 (cli) (built: Feb 24 2006 16:34:55)
Copyright (c) 1997-2004 The PHP Group
Zend Engine v2.0.4-dev, Copyright (c) 1998-2004 Zend Technologies

I wrote a script which basically sits in a while loop doing:

while (!feof(STDIN)) {
$line = fgets(STDIN);
// do something with $line
}

I pipe a tail command into this script like:

tail -n0 -F /var/log/mystuff.log | php -c /etc/php.ini myscript.php &

Everything works fine until logrotate rotates mystuff.log. Then the
script just hangs there and no longer processes anything. It doesn't
seem to drop out of the while loop but I have to put some more debugging
statements in to see if I can figure out what is going on. Any ideas. I
don't really get how to deal with feof when the file is rotated.

I believe you can configure logrotate to shut down you script and launch it
again. That's what allows, for instance, to get Apache logs rotated. Could
that be a solution?
