Patch looks good to me.

--Wez.

Anything against this:

If not, I'll apply it by the end of the week with some new tests.

New Comment:

I'd rather like to see proc_terminate act like documented:

"proc_terminate() allows you terminate the process and continue with
other tasks. You may poll the process (to see if it has stopped yet) by
using the proc_get_status() function."

If a known workaround is to send posix_kill, which does... exactly what
proc_terminate is supposed to do, why not implement proc_terminate as:

stat = proc_get_status(proc);
if(stat['running']) posix_kill(stat['pid'], sig);

?

• update the $proc options as needed. That would be much more useful.
  Additionaly not every signal actually kills process, so resource should
  not be destroyed after SIGTERM.
  Please correct code, not docs.

Description:

After sending a signal via proc_terminate() to a process, the process
resource gets closed immediately.
This means that calling proc_get_status() afterwards, will throw a
warning about an invalid process resource.

This behaviour is somewhat cumbersomely, since you're unable to check
if it was your signal which has caused the process to terminate or if
the process has stopped.

Is this a bug or an undocumented behaviour?

BTW:
Sending a signal via the shell or through posix_kill(), will retain the
status for the first proc_get_status() call.

Reproduce code:

<?php
$descriptors = array(
0 => array('pipe', 'r'),
1 => array('pipe', 'w'),
2 => array('pipe', 'w'));

$pipes = array();

$process = proc_open('/bin/sleep 120', $descriptors, $pipes);

proc_terminate($process);
var_dump(proc_get_status($process));

?>

Expected result:

array(8) {
["command"]=>
string(14) "/bin/sleep 120"
["pid"]=>
int(23011)
["running"]=>
bool(false)
["signaled"]=>
bool(true)
["stopped"]=>
bool(false)
["exitcode"]=>
int(-1)
["termsig"]=>
int(15)
["stopsig"]=>
int(0)
}

Actual result:

Warning: proc_get_status(): 7 is not a valid process resource in ...
