There's a class for generating TTH compatible with DC clients (DC++, StrongDC, ...) which uses mhash() with tiger algorithm:

This will work better, in your function you can just use the constant function to pull in the actual value of MHASH_SHA512 or whatever.
function getHashNotWorking($argStrHashMethod, $argStrString)
{
$strHashMethod = 'MHASH_' . $argStrHashMethod;
$strHashedString = bin2hex(mhash(constant($strHashMethod), $argStrString));
return $strHashedString;
}
now:
echo getHashNotWorking('SHA512', 'some string');
works how you want it.

function getHashNotWorking($argStrHashMethod, $argStrString)
{
$strHashMethod = 'MHASH_' . $argStrHashMethod;
$strHashedString = bin2hex(mhash($strHashMethod, $argStrString));
return $strHashedString;
}
echo getHashNotWorking('SHA512', 'some string');
This will return an error about the mhash function expecting a long type instead of a string.
=============================
for ($intI = 0; $intI <= mhash_count(); $intI++)
{
$arrHashTypes[mhash_get_hash_name($intI)] = $intI;
}
function getHashWorking($argStrType, $argStrString)
{
global $arrHashTypes;
$strHashedString = bin2hex(mhash($arrHashTypes[$argStrType], $argStrString));
return $strHashedString;
}
echo getHashWorking('SHA512', 'some string');
This will return the hash with the desired hash method

Since it seems that the tiger hash bug has been labeled "bogus" here is a fix to give a correct result. I'm not a binary expert so if you come up with a better fix please let us know. Just do your MHASH_TIGER as normal then send the unaltered binary into tigerfix and you get a proper HEX return.
function tigerfix ($binary_hash) {
$my_split = str_split($binary_hash,8);
$my_tiger ="";
foreach($my_split as $key => $value) {
$my_split[$key] = strrev($value);
$my_tiger .= $my_split[$key];
}
$my_tiger_hex = bin2hex($my_tiger);
return $my_tiger_hex;
}

To enable mhash on RHEL/Fedora Core/other RPM-based Linuxes without rebuilding PHP, get the php-mhash and mhash RPMs at http://phprpms.sourceforge.net/mhash

MHASH_HAVAL256 , MHASH_HAVAL192, etc...
refers to the HAVAL hash with 3 rounds.
To use HAVAL with 4 or 5 rounds, you have to
recompile the mhash library and either add
new hash names, or just change in mhash.c
the definitions of MHASH_HAVAL256,...
