I think this is a nice little script to track comings and goings on a specific page.

PHP Code:
              <?php
$today 
date("F j, Y, g:i a"); 
if (
$QUERY_STRING!= ""){ 
$url "http://".$SERVER_NAME.$PHP_SELF.'?'.$QUERY_STRING
}else{ 
$url "http://".$SERVER_NAME.$PHP_SELF


$output=$today."\t".$url."\t".$HTTP_REFERER."\t".$REMOTE_ADDR."\n";
$out fopen("/path/to/file.txt""a+"); 
fwrite($out$output); 
fclose($out);                  
             
?>
