[SOLVED]laravel php pbkdf2 login authentication

I have a existing table with hash pasword using hash_pbkdf2. For user registration, it success insert into mysql

    $string = mcrypt_create_iv(24, MCRYPT_DEV_URANDOM);
    $salt = strtoupper(bin2hex($string));


    $hash = hash_pbkdf2("sha1", $data['password'], $string, 1000, 24, true);
    $hash = strtoupper(bin2hex($hash));

    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'hashedpassword' => $hash,
        'salt' => $salt,
    ]);

I having trouble to log in using it. here is my code

    $found_salt = DB::table('users')->where('email', 'sicksand@gmail.com')->first();
    $salt = $found_salt->salt;

    echo "Salt : ".$salt."<br>";
    $hash = hash_pbkdf2("sha1", "password", $salt, 1000, 24, true);
    $hash = strtoupper(bin2hex($hash));

    $userlogin = [
            'email' => "icksand@gmail.com",
            'hashedpassword' => $hash
    ];  
    echo "Hash : ".$hash."<br>";


    if(Auth::attempt($userlogin)) {

        echo "success";
    } else {
        echo "not success";
    }

The salt value is the same but the hash value does not match. Hoping someone can help. Thanks.
