In response to your first question. File stores are something a computer
does very very fast (might want to add some error catching to this)..
$i=0
while() {
count_index($i)
$i++;
}
function count_index ($i) {
$fp = fopen('count.txt', 'w');
fwrite($fp, $i);
fclose($fp);
}
In response to your second question. Sure provided you're not outputting
anything you can do header('Location: myscript.php'); every 25 - 30 seconds
to relaunch the script. Open your log file and start from the printed
value.
