Description:
------------
If you copy the example below from the manual, and run with 

error_reporting  =  E_ALL in php.ini

you get the result below.

Reproduce code:
---------------
<!-- Example 2 from http://us2.php.net/sscanf -->

<html><body>
<?php
// get author info and generate DocBook entry
$auth = "24\tLewis Carroll";
$n = sscanf($auth, "%d\t%s %s", &$id, &$first, &$last);
echo "<author id='$id'>
    <firstname>$first</firstname>
    <surname>$last</surname>
</author>\n";

?>
</body></html>

Expected result:
----------------
I expected the example from the documentation to work.

Actual result:
--------------
Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of sscanf(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in c:\inetpub\www\xxx\testsscanf.php on line 5

This is a simple documentation problem.  The &'s should be removed from that example.

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.
