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/mhashfunction 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

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.
There's a class for generating TTH compatible with DC clients (DC++, StrongDC, ...) which uses mhash() with tiger algorithm:http://kupershtokh.blogspot.com/2007/12/on-phpclub.html
