redis pconnect 的 select db 问题

        $r1 = new \Redis();
        $r1->pconnect('/redis.sock');
        $r1->select(1);

        $r2 = new \Redis();
        $r2->pconnect('/redis.sock');
        $r2->select(2);
        $r2->set('a','r1');
        
        var_dump($r1->get('a'));
        var_dump($r2->get('a'));

输出都是r1，请问有有效解决方案吗?

pconnect换成connect
