Printing out session vars

nasium

I have recently started a project where sessioning is being used to track visitors/store information etc... While programming, I have ran into several debugging scenarios. While surfing the net I found a piece of code that spits out sessions vars but fails on my testing environment.

When I run this sample, I get back the following:
echo "SESSION Variables from \$HTTP_SESSION_VARS ";
reset($HTTP_SESSION_VARS);
while (list ($key, $val) = each ($HTTP_SESSION_VARS)) {
print $key . " = " . $val . " ";
}

Warning: Variable passed to reset() is not an array or object in /home/www/zeropaid/jorge/test/session_info.php on line 41

Warning: Variable passed to each() is not an array or object in /home/www/zeropaid/jorge/test/session_info.php on line 42

My initial thought is that I have empty sessions vars, I am incorrect. I can login in as "user" and authenticate against my UserTable.

Have you tried...

var_dump($_SESSION);

??

That whole loop could just be replaced by var_dump($HTTP_SESSION_VARS);. This will also tell you what type of variable $HTTP_SESSION_VARS is.

If you're doing this inside a function, then the answer to your problem is that $HTTP_SESSION_VARS is not set. It's only an ordinary global variable, and doesn't automatically get set to any value inside a function.

Perhaps you'll get better results using $_SESSION instead; that does automatically get set inside functions.
