WARNING, when using proc_open, your child will NOT get the parent php process's PID by using posix_getppid() , it will actually get the pid of a shell ( /bin/sh ? ) started by php, which in turn starts the child.  i don't currently have a good workaround for this, but i'm working around it by having the parent write it's pid to a file and having the chidren read the file
