This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.
Thank you for the report, and for helping us make our documentation
better.

Should be a documentation problem for the sake of backwards
compatibility, though I don't think this feature is useful anyhow.

<?php
var_dump(ord(chr(32) | chr(64)));
var_dump(32 | 64);
var_dump(ord(chr(127) & (chr(32) | chr(16))));
var_dump(127 & (32 | 16));
var_dump("ABC" | " bc"); // should result in "abc"
?>
If a bitwise operation are performed between two string nodes, that
ends up with the results of that operation of the values of each
character's character codes.

It is not a session related problem, but a string conversion problem.
Below is a script which shows the problem. When doing test, remember
that the values should be based on a power of two, that is: 0x01, 0x02,
0x04, 0x08, 0x10, 0x20, ...
-------------------------
<html><head></head><body>
<h1>ORing Values</h1>
<?
do_table( 1, '1', 8, '8' );
do_table( 2, '2', 8, '8' );
do_table( 2, '2', 4, '4' );
do_table( 2, '2', 16, '16' );
do_table( 1, '1', 16, '16' );
?>
</body></html>
<?
function do_table( $val_1_num, $val_1_txt, $val_2_num, $val_2_txt )
{
?>
<br>
<table border="1">
<tr>
<th></th>
<th>Value 1</th>
<th>Value 2</th>
<th>Raw OR</th>
<th>strval OR</th>
<th>0+ OR</th>
</tr>
<tr>
<td>Number</td>
<td align="center"><?= $val_1_num ?></td>
<td align="center"><?= $val_2_num ?></td>
<td align="center"><?= $val_1_num | $val_2_num ?></td>
<td align="center"></td>
<td align="center"><?= (0 + $val_1_num) | (0 + $val_2_num) ?></td>
</tr>
<tr>
<td>Text</td>
<td align="center"><?= $val_1_txt ?></td>
<td align="center"><?= $val_2_txt ?></td>
<td align="center"><?= $val_1_txt | $val_2_txt ?></td>
<td align="center"><?= strval($val_1_txt) | strval($val_2_txt)

Please add a short but COMPLETE example script which clearly
demonstrates the problem.

I stated that strval() does not work. However a kludge that DOES work
is:
echo "Val : ".((0 + $opt['time']) | (0 + $opt['date']));
