Fire and forget

Is there a way to fire off a process not dependant on the PHP process tree? (Talking windows CLI version here)

Basically I want to run a program which will not end, it is a modal window if I remember my terminology properly... but I want my PHP script to finish anyway.

what about a clients-side js call opening a new window which invokes the page?

Guess it would depend on what the trigger criteria is for the...

There are no pages involved, this is a command line interface.

what about exec?

Maybe exec combined with the following note will work, the question will be how to redirect for this particular program. I'll have to tinker.


Note: If you start a program using this function and want to leave it running in the background, you have to make sure that the output of that program is redirected to a file or some other output stream or else PHP will hang until the execution of the program ends.

First of all, on what platform are we talking about?

Windows 2000 Server, using PHP 4.3.5... but not the standard executable, I'm using the CLI executable.

So after doing some research the solution is exec combined with redirecting the output to dev/null (or whatever the Windows equivalent is)... either one alone isn't enough.

The easiest way is likely to use PHP to configure the Win32 "at" service to run the other programs immediately.

Ah yes, I remember using that in the past.

Unfortunately I won't see this server again for a couple weeks so I'll find out then.

Thanks both of you.
