Cookie no workie

[jzeman]

I'm just trying to set a simple cookie... a counter that shows the number of times a particular user visits a page:

<?
$count++;
setcookie ('count', $count);
echo "Your visit count: $count\n";
?>

I get an error and a warning on this code. This is all the code in the file "default.php" which is in the root directory on the web.

[10-Jun-2003 20:52:25] PHP Notice: Undefined variable: count in c:\inetpub\wwwroot\TMPossgtgal31.php on line 3

[10-Jun-2003 20:52:25] PHP Warning: Cannot modify header information - headers already sent by (output started at c:\inetpub\wwwroot\TMPossgtgal31.php:3) in c:\inetpub\wwwroot\TMPossgtgal31.php on line 5

Am I missing something? There is nothing in the file before the opening <? tag.

BY the way... the web output

Notice: Undefined variable: count in c:\inetpub\wwwroot\TMPu5ygogas1e.php on line 2

Warning: Cannot modify header information - headers already sent by (output started at c:\inetpub\wwwroot\TMPu5ygogas1e.php:2) in c:\inetpub\wwwroot\TMPu5ygogas1e.php on line 3
This is the count: 1

note the correct line numbers.. they were off before as I pasted an older error log entry.

PHP is version 4.3.2
IIS is 5.1

You probably should use $_COOKIE['count']
As for the headers cannot be sent warning, maybe you have a blank line at the top of the script?

tried the above suggestions... no joy there. any other ideas? a server issue?

my default.php is attached. (renamed to .txt so I could post).

note that I'm not expecting the count to increment in the cookie- for now I'd be happy to store the text "count" as written.

This seems to work:

<?php
if (isset($_COOKIE['count'])) {
	if (empty($_GET['logout'])) {
		$count = $_COOKIE['count'];
		$count++;
		setcookie("count", $count, time() + 3600);
		echo 'Cookie contains value: ' . $count;
	}
	else {
		setcookie("count", "", time() - 3600);
		echo 'Cookie has been deleted';
	}
}
else {
	setcookie("count", 0, time() + 3600);
	echo 'Cookie contains value: 0';
}
?>

though due to page being cached (I presume) it needs to be refreshed for the counter to increment

That works great.

The code I was using before was from PHP for Flash by Steve Webster, Chapter 6, page 182. I wonder if it is an issue with the version of PHP?

Anyway, your code works like a champ. Thanks for the help!!!
