Test Session problem

Anon

I have problem when execute session test script:
<?
session_start();
session_register("SESSION");

if (! isset($SESSION)) {
$SESSION["count"] = 0;
echo "<li>Counter initialized, please reload this page to see it increment";
} else {
echo "<li>Waking up session $PHPSESSID";
$SESSION["count"]++;
}
echo "<li>The counter is now $SESSION[count] ";
?>
I get this warnings: "Warning: Cannot send session cache limiter - headers already sent (output started at d:\server\mate\www\probe\tmpbjpwhbkp0.php:2) in d:\server\mate\www\probe\tmpbjpwhbkp0.php on line 3

Warning: open(/tmp\sess_fb4ab804fafb574e6a841d2538d6c0dc, O_RDWR) failed: m (2) in d:\server\mate\www\probe\tmpbjpwhbkp0.php on line 3
What is the problem. Configuration or?

Not at all clear why you're going to such trouble just for a counter:

<?php
session_start();
if(!isset($SESSION['count'])
{
$SESSION['count']=0;
echo...
}else{
$_SESSION['count']++;
echo...
}
?>

Should be enough.

You have two problems causing warnings.

1) The script had already output stuff before you called session_start(). It may have been html, it may have just been a blank line at the top of the file before the forst <?, but it was output. All that is "content". And the http protocol species that all headers for a request have to be sent before any content.

2) You need to fix your php.ini so that it refers to a real directory for storing session data. Right now it says "/tmp" - which is the conventional temporary directory on a Unix machine. You need to change it to a suitable directory name on your system. Some people use c:\windows\temp, but I think you might as well have a d:\temp directory and use that.
