使用session_write_close（）时PHP保存会话;

Question

I've one page where i do a long polling i've to use at the begin of this page this

session_start();
session_write_close();

Because :

to prevent concurrent writes only one script may operate on a session at any time

So if i do not and the long polling is running the user will not be able to load another page.

So accessing to my data in session from this polling page is possible but at some point in my script i've to save my session back to the server because i made some change in it.

What's the way to do it?

That will be very nice it'll be a way to do something like

session_write_open();
//do stuff
session_write_close();

But the session_write_open() doesn't exist!

Thanks

Before you make some change to the session, call session_start again. Make the changes, and if you still do not want to exit call session_write_close once more. You can do this as many times as you like.
