To the object-oriented thinking.

1. If the methods in a class do not have a relationship with each other, that is, when there is no state, is it possible to change all the methods to static statics?
2. are multiple users in PHP accessing a class at the same time to new multiple times? If New times is not very resource-intensive, it is better than static?
3. Thank you for your speech, I sent a few questions before you all wood have to answer, if you know, also please help younger brother troubleshoot answer.

1. Is
2. Yes, not (even static, not shared between multiple accesses, each request will be new separately, but not multiple times during a request processing)
