base on the link I sent...
I have modified it in order to make it a little bit stronger...You can try to get it even stronger. I suggest u use as a salt, the username for instance..or some whatever u want.
function generateHash($sPlainText,$sSalt)
    $aPlainText     = str_split($sPlainText);
    $sPlainText     = '';
    foreach($aPlainText as $sChar)
        $sPlainText.= $sSalt.$sChar;                     
    return $sPlainText;
