I have a web-based php script that gathers information and then passes it off to several functions, which execute several other php scripts. The problem is that the main php script does not return until all the processes have signaled and is taking about 30 sec to complete. There is no need for the child processes spawned by the main php script to signal. I would like to spawn and detach them to finish in the background; thus, dramatically reducing the load time of the main php script.
It has been suggested to me to use the & with the shell_exec function, but this still requires the child processes to signal.
Another suggestion was to use the pcntl_fork function, but my reading suggest that this is not to be used with web-based applications and does not compile in with mod_php (only the binary version). If I were to use the binary version would I even be able to detach the forked child processes? Doesn't pcntl_fork still require the child processes to signal to the parent before exiting otherwise becoming zombie processes?
Any suggestions on the best way to handle this?
Respectfully,
Gary
