Redis objects behave differently in the laravel/framework and in my apps using the laravel/framework.

description

When I try to run the following code in my app, it raises an exception with setnx.
We also have a similar problem with hsetnx.

code

use Illuminate\Support\Facades\Redis;

~~~

Redis::multi();
Redis::setnx("aaa", "bbb");
Redis::exec();

~~~~

exception

{
  "message": "Object of class Redis could not be converted to int",
  "exception": "ErrorException",
  "file": "/src/vendor/laravel/framework/src/Illuminate/Redis/Connections/PhpRedisConnection.php",
  "line": 100,
}

This means that after using Redis::multi(), the return value of the Redis object is a However, in PhpRedisConnection#setnx, there is an attempt to convert it to an int The reason for this is because they are doing it.
The phpredis documentation also states.

multi() returns the Redis instance and enters multi-mode. Once in multi-mode, all subsequent method calls return the same object until exec() is called.

Based on the above, I thought it was a bug and forked the laravel/framework repository.
The branch is 6.x
And I was able to convert a Redis object to an int.

I don't understand why there is such a difference between the two, so I was wondering if you could help me out.

code

use Redis;

~~~

$r = new Redis();
var_dump(get_class($r));
var_dump($r);
var_dump((int)$r);

~~~~

output in the forked laravel/framework

string(5) "Redis"
class Redis#86 (0) {
}
int(1)

output in my apps

string(5) "Redis"
object(Redis)#1020 (0) {
}

ErrorException : Object of class Redis could not be converted to int
