Description:
------------
Files functions doesn't work with relative paths since the current working directory is deleted during the "exit" line. Is this a bug or a feature ? :-)

Test script:
---------------
function debug_cwd(int $i)
{
    syslog(LOG_DEBUG, "getcwd [$i] -> " . getcwd());
}

function shutdown()
{
    debug_cwd(4);
    chdir('/var/www/website');
    debug_cwd(5);
}

chdir('/var/www/website')
debug_cwd(1);
register_shutdown_function('shutdown');
debug_cwd(2);
fastcgi_finish_request();
debug_cwd(3);
exit;
debug_cwd(6); // will not be displayed


Expected result:
----------------
$> tail /var/log/syslog
Dec 17 15:09:43 hosting php: getcwd [1] -> /var/www/website
Dec 17 15:09:43 hosting php: getcwd [2] -> /var/www/website
Dec 17 15:09:43 hosting php: getcwd [3] -> /var/www/website
Dec 17 15:09:43 hosting php: getcwd [4] -> /var/www/website
Dec 17 15:09:43 hosting php: getcwd [5] -> /var/www/website

Actual result:
--------------
$> tail /var/log/syslog
Dec 17 15:09:43 hosting php: getcwd [1] -> /var/www/website
Dec 17 15:09:43 hosting php: getcwd [2] -> /var/www/website
Dec 17 15:09:43 hosting php: getcwd [3] -> /var/www/website
Dec 17 15:09:43 hosting php: getcwd [4] -> /
Dec 17 15:09:43 hosting php: getcwd [5] -> /var/www/website

I only use PHP-FPM with Haproxy with FCGI, not Apache.

I understand there is a little notice that inform it can change during the shutdown function... but... is this normal for our use / need ? Probably not.

Why don't you are able to restore the CWD during the shutdown function ? Since i am able to write a one-line fix ; it should be evaluated the feature to not change the CWD during the shutdown function.
