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.

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

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

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