Following the 'Session handling' documentation and expriencing problems with a production script, I wrote the following test script:

echo "Session ID : ".session_id()."<BR>\r\n";
if( !isset( $_SESSION['Test'] ) )
	$_SESSION['Test'] = "bla bla bla";
	echo "Defined : ".$_SESSION['Test']."<BR>\r\n";
	echo "Existing : ".$_SESSION['Test']."<BR>\r\n";

which I expect to set the 'Test' session variable on the first call to the page and then return the 'Test' session variable on subsequent calls to the script.

This works FINE with PHP 4.1.1 but DOES NOT WORK with PHP 4.1.2 (though the session ID is the same). I had to revert to the old 'session_register()' function for the script to work in PHP 4.1.2, $HTTP_SESSION_VARS not working either.

Any clue ?

It's propably the same issue as everyone else is having.
Please try the PHP 4.2.0RC3 from
as others have reported that it works fine for them.

And don't forget to replace the php4ts.dll in your system
with the one in the 4.2.0RC3 package.

This bug is EXTREMELEY ANNOYING, and very hard to replicate. Sometimes it happens, other times it doesn't. Seems to happen more when the server has been idle for awhile.

The big problem here, is that I cannot upgrade my PHP, because I am using a remote hosting company that has 4.1.2 installed.

I have no idea what to do, and I'm extremely frustrated.
