on Windows platform proc_terminate() does not kill sub-processes that are not handling kill signals. It happens even if you call xxx.exe and call proc_terminate() the process will remain active.
The solution is instead of calling proc_terminate() is to call the user-defined kill() function (already win/unix optimized)
After that need to close all pipes and execute proc_close().
function kill($pid){
return stripos(php_uname('s'), 'win')>-1 ? exec("taskkill /F /T /PID $pid") : exec("kill -9 $pid");
}
function killall($pids) {
$os=stripos(php_uname('s'), 'win')>-1;
($_=implode($os?' /PID ':' ',$pids)) or ($_=$pids);
return preg_match('/success|close/', $os ? exec("taskkill /F /T /PID $_") : exec("kill -9 $_"));
}
Example:
$pstatus = proc_get_status($resource);
$PID = $pstatus['pid'];
// other commands
kill($PID); // instead of proc_terminate($resource);
fclose($pipes[0]);
fclose($pipes[1]);
fclose($pipes[2]);
proc_close($resource);
