Process::kil() not killing service process properly

[GoogleCodeExporter]

Actually, that piece of code has always been problematic. In some systems, it 
is working perfectly (as it is in my 
Debian Lenny server); however, some other Debian servers too are having 
problems (and they have solved the 
problem by using --ppid instead of -pid).
The reasons of this are still unknown.

I'm going to try your solution, and see if this makes some things better.

I was experiencing similar issues as mikeytrw on Centos 5.3 server, and wanted 
to confirm if child process 
from the parent(PushMonitor needed killing). It turns out that it's managed 
fine, and you dont need to kill all 
child processes that belong to the parent, since only one happens at a time. 

I stuck in the code fragment before i sent a message to see what child id's 
there are and forced it to fail by 
choosing an invalid server ip for the client.  it found the one child process 
and the ps command to find the 
process.  
                $moo = getmypid(); //get parent pid (PushMonitor.php)
                $pids = preg_split('/\s+/', `ps -F --ppid $moo`); //confirm what ps pulled up
                print_r($pids);


and i guess one modification on mikeytrw's code that i would put is 

replace:
proc_terminate($this->pointer);

with:

                        if(!proc_terminate($this->pointer)){
                          posix_kill($ppid, 9); //if it cannot terminate pointer,kill 9
                        }

i guess just incase it can't terminate for whatever reason, it can still kill 
the process. someone can correct me 
if this is redundant.
