for($n = 0; $n<10; ++$n) {
}
print $n;
will print 10, not 9. $n is incremented the last time control returns to the for - ++$n happens before the $n<10 check, because the loop control statement means
1. If this is the first iteration, $n = 0
2. if $n < 10, execute the loop body...
3. .. then ++$n
4. goto 1
