persistent php connection?

Question

Is it possible to have a php script pause at a certain point wait for an ajax response, then continue executing?

If not, what is the most appropriate way to store the current state of a script (all defined variables ect) untill it in invoked again?

Answer 1

Making it wait for an ajax response which could never come sounds like a very bad plan (apart from being impossible due to the nature of http as a stateless protocol).

What's wrong with using session to persist user data (you can store objects in the session)? It won't serialize the whole state automagically though.

Answer 2

Not how php works, or ajax really either. Each request is independent. You can use a session.

Answer 3

我认为您正在寻找Comet 链接文本 -这是反向Ajax的一种形式，它无限期地保持连接的打开状态-尽管我不认为您会拥有一个PHP脚本来等待它...

Answer 4

If you want to get in your php script response that you would normally access via ajax then just use curl functions. Curl will wait for the response to arrive.
