Your array appears to be sortable in (reverse) date order.

Try the following in the php cli:

<?php

$newsbrief[] = "110101_oldest";
$newsbrief[] = "110303_newest";
$newsbrief[] = "110202_middle";

rsort($newsbrief);

foreach ($newsbrief as $filename)
{
echo "$filename\n";
}
?>

<http://uk3.php.net/manual/en/function.session-start.php>

Nothing there about session_start being deprecated

session_register is deprecated, see:

<http://uk3.php.net/manual/en/function.session-register.php>

Just remove the "session_register();" line. I don't think it does what
you think it is doing here. session_register() is used to register
session global variables.

As far as I can tell, session_register() called _with_no_parameters_
*before* session_start() will just call session_start(), and
session_register() called _with_no_parameters_ *after* session_start()
will do nothing at all.

Use the superglobal $_SESSION[] array instead of registering variables
with session_register().
