如何在php8.0中输入Juggle?

理解 Type Juggling

# Payload: { 'token': 0 }

$payload = json_decode(json_encode(array('token' => 0)));
$token   = 'RaNdOmStRiNg1!';

echo "[PAYLOAD] " . gettype($payload->token) . "({$payload->token}) - ";
echo "[TOKEN] {{$token}} - ";

if($token != $payload->token) {
    die('Access Denied');
}

echo 'Access Granted: Type Juggling Bypass';

如果我们在 3v4l != !== 而在>8.0中,类型杂耍发生了。

== 和 !==
