Php Counting Script

I'm looking for a script that when a viewer looks at the page it will add one to the previous number that there was. Mainly refreshing, it will add a number. I also need it to clear when you leave the page. Maybe sessions? I know php well, but I cant seem to get this. I know I need something like $email + 1 = $emails idk something like that but it never works.. just takes it and adds one and then thats it.. doesnt keep adding, I also need to be able to have more than one counter on the same page. Maybe having the counter name as a random integer, something like that. I'm thinking.

something like that to just keep adding one from on...over and over and then clear when the page is closed, or when you click a button. maybe make it redirect and then before it redirects clears the thing, or assigns a new id for the counter and then clears all the counters when you close the page.

Use a while loop, php.net

I have looked at a lot of tutorials, and also I have tried everything. Can someone please give me an example or anything to help me get on the right track.

well what exactly are you looking for something that counts the number of page refreshes.. Will write you a small script soon possibly using sessions.

<?php
ob_start();
session_start();

if(!$_GET['clear']){
$_SESSION['emails'] = 0;
$_SESSION['emails']++;
} else {
$_SESSION['emails'] = 0;
header("Location: ".$_SERVER['PHP_SELF']);
}

echo $_SESSION['emails'];
?>

To clear it, add ?clear=1 to the filename/

just giving me straight 1's no matter how many times I refresh it.

damn, sorry - its late here & i've had a long day (i'm setting the value to 0 then adding 1 to it each time, heres the new code:

<?php
ob_start();
session_start();

if(!$_SESSION['emails']){
$_SESSION['emails'] = 0;
}

if(!$_GET['clear']){
$_SESSION['emails']++;
} else {
$_SESSION['emails'] = 0;
header("Location: ".$_SERVER['PHP_SELF']);
}

echo $_SESSION['emails'];
?>

ok your awesome... How do I clear it and maybe is it possible to make it to where I can have more than one up so they dont interfere with eachother?

<?php
ob_start();
session_start();
$self = $_SERVER['PHP_SELF'];

if(!$_SESSION['count-'.$self]){
$_SESSION['emails'] = 0;
}

if(!$_GET['clear']){
$_SESSION['count-'.$self]++;
} else {
$_SESSION['count-'.$self] = 0;
header("Location: ".$self);
}

echo $_SESSION['count-'.$self];
?>


This script will have its own counter for each file.


To clear:
if the script was called c1.php
clear the count by accessing c1.php?clear=1

everytime i start a new one that is already running it just resets the other one that is already running to restart back at 1.. I made it so that whenever it redirectes to the other redirecting.. itll also clear the field.. so everytime I start a new one, it will reset it back to 1, it seems that like all the sessions are named the same, maybe by giving it a name of a random integer or something.
