Session Help - Simple Counter Reset

worm

Hi guys,

I'm trying to wrap myself around how sessions work. I'm using a simple counter script to begin the learning process.

Aren't sessions specific to each individual browsers instance? Once I open up a new browser, it retains the counter value of the last browser window that was opened. How can I make the counter reset to 0 each time I open a new browser window? Here's the script that I am using.

<?php 
session_register ("count"); 
$count++; 
?> 

Hello visitor, you have seen this page <? echo $count; ?> times.

Thanks guys. 🙂

anyone?

hi-liter

there's a good tutorial on session, including a counter on phpfreaks

http://www.phpfreaks.com/tutorials/41/6.php

good follow the entire tutorial.

hth.

Try building your own session handler. First check to see if individual browsers do have individual session id's with the following script.

echo($_COOKIE['PHPSESSION']);

Then if you find that they are you can build your own MySQL based session handler quite easily. If you need more help just ask.

Good luck
Rob

It seems that my counter will not reset when I am using IE 6. It works fine on IE5. Are there any known problems with IE6?

hi-liter

w/o code, hard to say. try tho, adding

header("Cache-control: private");

right under your

session_start();

like:

session_start();
header("Cache-control: private");

though really not sure what the issue is. the tutorial code from phpfreaks.com works for me w/ ie6.

Well, here's what I am using:

<?

// start the session
session_start();
header("Cache-control: private"); 
session_register('count');

if ($_SESSION['count'] == 0) {
    $_SESSION['count'] = 1;
} else {
    $_SESSION['count']++;
}

echo "You've been here " . $_SESSION['count'] . " times";

?>

And here's the link to my online example. Try it with IE6 and see if it works for you:

Hmmm ... weird! It also won't work on IE5 when I click the above link and open up a new window. It only resets when I manually open up a new browser and type (or copy & paste) the URL. Any thoughts on that?

hi-liter

w/ session variables the session is when the browser is open. close out the browser and fire it up again a new session is started when you go to the url. to destroy while leaving the browser open you'll have to

session_destroy();

or delete the session

session_unregister('count');

not sure i get tho, what is the goal to accomplish.
hth.

hi-liter

or you could reset the session count t0 1:

<?php
// start session
session_start();
header("Cache-control: private"); // ie6 fix
session_register('count');
$_SESSION['count'] = 1;
?>
