This example will show the current user id then set the
effective user id to a separate id using
posix_seteuid(), then show the difference between
the real id and the effective id.
<?php
echo posix_getuid()."\n"; //10001
echo posix_geteuid()."\n"; //10001
posix_seteuid(10000);
echo posix_getuid()."\n"; //10001
echo posix_geteuid()."\n"; //10000
?>
