Hello!
I am executing an external command from a PHP script, using the exec function. Since this program can take more than 1-2 minutes to run, I thought I should use a "Loading page...please wait". What I need is to be able to get the process id from the external program that is being run and, when this finishes, I'll start outputting the results.
Is there a way to do this?

Why do you need the process id? Will the second argument to exec() not work? If not, you may also want to review some of your other System program execution [php.net] options.

Your browser may time out in that amount of time, rendering the idea not so reliable . . . current discussion on fork() [webmasterworld.com] to allow it to run as a "background process." Fork will return the PID of the child process.
