exec background process

I want have PHP call another process (another PHP script at the moment
but it may end up being a binary) in the background and not wait for
process to complete, but rather instantly jump the the next line of
code.

I've tried things like:

exec("./script.php &"); // script.php has executable permissions set
exec("at -f ./script.php now"); // and #!/usr/bin/php at the top of
the code

Neither seem to work. They both execute script.php, but both hang
around until script.php has completed.

Any ideas?

Hi Matt,

You could use proc_open for this:

proc_close(proc_open ("./script.php &", array(), $foo));

The empty array for the output specs prevents opening any pipes to the new
process, so proc_open doesn't wait for the execution of script.php to
finish - the last parameter is just there because it has to be.
proc_close() closes the process immediately, so your PHP script doesn't
stop.
