some question of Thread and Process in php

1)
If I run: "php myphp.file" in command line, sure it is a process of php. I can see it by "ps" command. But if that is run php script by Apache, It should be a process, or a thread belong to Apache?

2)
How can start a lot of thread by php? The program run by function "include()" is a process or thread? I heard someone said just object can be use in thread, isn't it?

3)
I need to run many php program script simultaneously, I found the "include()" run them one by one, that's not right. How can I run them at the same time?

4)
Which spend more resource of system? thread or process?

Thanks help.

1) if PHP is a module of apache then apache runs the PHP code inside it's processes.

2) include just reads sourcecode. why would that start a thread?

3) include does not run any scripts (read the manual) If you need to start many scripts at the same time then that is exactly what you should do, start many scripts at the same time.

4) a thread is merely a process controlled by a mother-process, so there is not much difference in resource usage.
