sessions help

gunhoe86

i'm trying to write a script using sessions where every time a user loads a page, a variable named 'hits' is incremented by 1, and when they leave the site, the value of 'hits' is logged in a text file. is this even possible? here's what i have so far:

<?php
session_start();
session_register('hits');
?>


<body>
<?php
$hits++;
echo ("$hits");    //just for testing purposes

//heres where i need the script to log 'hits' if the user
//leaves the site
?>

i have this on each page, but it always just echoes 1. and is there a way to wait until the user leaves the site to log the value of 'hits'? and if so, how can i do it?

thanks

<?php
session_start();
if (!isset($_SESSION['hits']))
  $_SESSION['hits']=0;
echo 'This is your visit #'.(++ $_SESSION['hits']);
?>

this should do the job

Also

 

<?php //note this script assumes session.auto_start is set to one in your c:/windows/php.ini

if( session_is_registered('hits') ) {
$hits++; } else {
session_register('hits')
$hits++; }


$msg = "You have visited this page ".$hits. "times.";

?>
<html>
<?php echo($msg);
</html>

Would work, but I' not sure about the storing the hits.

you're probably better off storing the hits in a cookie, and store them on each page load - that way, you dont need to detect when a user has left your site

thanks for all the help

i thought about storing 'hits' on every page load, but then my .txt document would say something like:

1-2-3-4-5-6-7-8-9-10 etc.

is there anyway to combine a javascript 'onUnload' command (or whatever it is) with the php code that writes to the .txt file?
