What happens when a script runs to long

[Anon]

i'm curious what happens when a script runs for too long. like a infinite loop or just waiting for data too long.

1.)when does the server kill the script if the user keeps on waiting for the output? i.e. the user doesn't press the STOP button or BACK button on his/her browser.

2.)what happens when let's say the user press's the STOP button on his/her browser? does apache immedietely kill the script? or is it the same as 1.)

3.)if the program is executing another program and is killed is the program executed killed too?

4.)the differences in the above 1~3 questions if any when running php as a CGI or as an apache module

thanks

By default, the script ends after 30 seconds, or when the clients aborts the connection.
Don't kwon what happens if another program is called by PHP.
This behavior is the same with a cgi or an Apache module.
These settings can be overriden in the php.ini or in the script itself.
I've done this once in the script because I had to send like thirty thousand mails, but can't remeber how it was, You can check the manual.
Hope I was clear.
