Changed OS to Irrelevant

This is a bug in ext/hash/hash_tiger.c It looks like there was a mistake during refactoring. I am attaching a patch.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

See changelog in documentation.

This is quite unfortunate, We have thousand of passwords stored in the wrong hash order. It looks like we have to keep PHP 5.3 for a long time.

Yeah, I think we need to come up with a way to support both or else it leaves 
people without an easy way to fix those hashes. Technically I guess you can 
reconstruct it from the raw by flipping the bytes, but that is rather error-
prone.

Thanks mike. I should have read the commit message first. Sorry for the false allegation.

Sorry folks, here's a one-liner to re-create pre-PHP-5.4 hashes:

implode("", array_map("bin2hex", array_map("strrev", 
str_split(hash("tiger192,3", $input, true), 8))));

Truncate the result to the length you need (128,160,192 bits).  Make sure every 
array value is 16 hex digits long or else lpad it with literal 0s.

If you used 192 bit tiger, you can use the following one-liner to create correct 
hashes from the wrong ones:

implode("", array_map("bin2hex", array_map("strrev", array_map("hex2bin", 
str_split($wronghash,16)))));

Thanks Mike and Rasmus for all your great help!

Here's something for the documentation team:

/* calculate pre-php-5.4 tiger hashes with php-5.4 */
function old_tiger($data = "", $width=192, $rounds = 3) {
    return substr(
        implode(
            array_map(
                function ($h) {
                    return str_pad(bin2hex(strrev($h)), 16, "0");
                },
                str_split(hash("tiger192,$rounds", $data, true), 8)
            )
        ),
        0, 48-(192-$width)/4
    );
}

The doc team would probably not notice an "not a bug" bug ;)

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.
