PHP's Single Thread Behavior and html Frames

[ashore]

I'm seeing some weird behavior in a frames-based application, which prompts me to ask the following.

Say I have an application that uses two html frames (Yes, deprecated; I know.)

In frame #1  I'm running a script that does a sleep().  How does that affect the script in frame #2?  Can it run while frame#1 script is sleeping?

(I'm trying to set up a test, but having some difficulty,so ... .)

You're telling the php parser back on the server to wait n seconds, so all php activity will halt :)

Have you actually tried anything? I just tried this scenario and, as I expected, the requests run independent of each other so a sleep in one script doesn't affect the processing of the other script at all.

Robert, agreed.  That's what I wd expect and have seen, I believe.

Now since PHP is single-threaded, when running two parallel php scripts in a single-user context - as in that frames-based html - the 2nd core in a multi-core CPU won't be dispatched.

Is that yr understanding, too?

You're having problems with session locks. See this http://php.net/manual/en/function.session-write-close.php

Hi Marcus,

You are correct, if we use session the it will happen.
