function salting($password,$encrypt=''){
    $pwd = array();
    $pwd['encrypt'] =  $encrypt ? $encrypt : create_randomstr();
    $pwd['password'] = md5(md5(trim($password)).$pwd['encrypt']);
    return $encrypt ? $pwd['password'] : $pwd;

}

PHP

/**
 * 生成随机字符串
 * @param string $lenth 长度
 * @return string 字符串
 */
function create_randomstr($lenth = 6)
{
    return random($lenth, '123456789abcdefghijklmnpqrstuvwxyzABCDEFGHIJKLMNPQRSTUVWXYZ');
}

function block_virtual($lenth = 6){
    $str = uniqid(mt_rand(),'123456789abcdefghijklmnpqrstuvwxyzABCDEFGHIJKLMNPQRSTUVWXYZ');
    $md5=sha1($str);
    $fan=md5($md5);
    return random($lenth, $fan);
}
