[Resolved] more session hell

[njm]

Further to my earlier problem with sessions - I'm now even more stumped.

This is the simple test script for sessions directly from Welling/Thompson: page1.php

The script is as follows:

<?
session_start();
$_SESSION['sess_var'] = "Hello, world!";

echo "The value of sess_var is: ".$_SESSION['sess_var']."<br />";
?>
<a href="page2.php">Next page</a>

as page2.php (the link) is

<?
session_start();
echo "The content of sess_var is: ".$_SESSION['sess_var']."<br />";
unset($_SESSION['sess_var']);
?>
<a href="page3.php">Next page</a>

however, on the same server. I have the following pages: www.bellcars.co.uk/accounts/

which use sessions fine (and more extensively). Anybody tell me what might have changed for me to get these errors. The server is V4.1.2, and I get a similar error with V4.3.1 on XP

Thanks, njm

You mean "Can't send session cache limiter - output already started in xx, line yy" ???

FAQ, that; you can't have any output to the browser prior to calling session start. Including any white space, HTML code, etc., etc.

Also, when I pull up your test pages, I get some funky little character up there ... whassup with that? Looks like

 

Maybe some shift in your character encoding and it's doing something weird as a result?

dälëcösp,

Thanks for the reply. I know there can't be any whitespace before session_start(), and I don't think there is any, especially on the test scripts, which is what makes this so puzzling.

The odd character is funny - it doesn't show up in IE6, but did when I checked in Firebird. I've changed character encoding from utf-8 to iso-8859-1, but it still appears. The test script doesn't even have explicit character encoding.

Any other ideas?

Well it looks like the culprit was Dreamweaver (MX on WinXP)

When I create the same test scripts in notepad and access them, everything works fine, so I guess it's something to do with how DW creates the pages, but I'm not quite sure what!

Thanks dälëcösp, for putting me on the right line of enquiry!

Well, that's what the forum's for, IMHO. Lucky for us I like Mozilla 😉

I much prefer Mozilla too, but the target audience was my office where we all use IE so I was doing all the checking in that 🙁

BTW, definitely was DW - reinstall fixed it!
