session variables

Hi I'm new to PHP. Having trouble with session variables. Hope someone can help me out...

register_globals is disabled
PHP Version 4.1.2
session.save_path is C:WindowsTemp
session.save_handler is files

the code i have:

<?php
session_start();
session_register();
?>
<head>
</head>
<body>
<?php
$_SESSION["count"]++;
echo $_SESSION["count"];
echo "<br/>";
echo session_id();
?>
<br/>
<a href="count.php">link</a>
</body>
</html>

however $count is not preserved (it doesn't count upwards). What am I doing wrong? Thx for any help.

RE: session variables

According to the docs if you have tack_vars enabled (do you?) and registered globals disabled "only members of the global associative array $HTTP_SESSION_VARS can be registered as session variables".

Which means that what you're trying to do won't work... You are trying to use $_SESSION but need to use $HTTP_SESSION_VARS.

Check out this snippet of code straight from http://www.php.net/manual/en/ref.session.php (From Example 1):

<?php
session_start();
if (isset($HTTP_SESSION_VARS['count'])) {
$HTTP_SESSION_VARS['count']++;
}
else {
$HTTP_SESSION_VARS['count'] = 0;
}
?>

That ought to accomplish what you want... Good luck!

RE: session variables

thx mcsherry

Track_vars is always enabled it says in the version I have. It also says that:

Use of $_SESSION (or $HTTP_SESSION_VARS with PHP 4.0.6 or less) is recommended for security and code readablity

so I think it should work really?
I will work on it tonight - let you know.
