You could have a table called say "hits" and then have code on each page which would add an entry to this table whenever they view a certain page. code could be:

  $ip = getenv("REMOTE_ADDR");
  $date = date("j M y G:ia");
  $page = $_SERVER[PHP_SELF];
  $sql = "INSERT INTO hits VALUES('','$ip','$date','$page')";
  $result = mysql_query($sql) or die(mysql_error());

This assumes a connection to the database has already been made. You will need to make the table with IP, Date and Page fields, plus an ID field as the primary key.

you could also add the username by using creating a session variable at login and inserting that into the database aswell.

You could then have a page that could retrieve information from this each time you refresh although you would want to put some limit on it otherwise it could potentially be a very large output - say limit it to the 10 most recent entries.

Additonally if its a large, multi user site...this way probably isnt very efficient at all and could result in a huge hits table

You would need the code on every page!
