Description:
------------
I have found a bug on page language.operators.html
[chm date: 2006-11-21]...

In the list of assignment operators (= += -= *= /= .= %= &= |= ^= <<= >>=), shouldn't &= actually be =&?

In testing ...

Reproduce code:
---------------
<?php
$a = 1;
$b =& $a;
$c &= $a;

echo $a, $b, $c;
++$a;
echo $a, $b, $c;
?>

Expected result:
----------------
111222

Actual result:
--------------
Notice: Undefined variable: c in D:\PHP Quickies\assignment_test.php on line 4
110220

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.

You're confusing the bitwise AND assignment operator (&=) with assigning a reference.

$a &= $b;

can be rewritten as:

$a = $a & $b;

Assigning a reference uses two separate operators, = and &, so it's not listed individually.
