Description: This is a pretty rudimentary way to keep track of unique hits, but It works.
<?
/* Just put this code into your index page, and put $unique_ip wherever you want the counter number. Be careful because the ip list file must be world changeable.
this is just a quick and dirty. If you feel that you want to flame me for this, don't bother,I know it sux.
Thanx,
joe
