win32_set_service_status — Update the service status
Informs the SCM of the current status of a running service. This call is only valid for a running service process.
The service status code, one of WIN32_SERVICE_RUNNING, WIN32_SERVICE_STOPPED, WIN32_SERVICE_STOP_PENDING, WIN32_SERVICE_START_PENDING, WIN32_SERVICE_CONTINUE_PENDING, WIN32_SERVICE_PAUSE_PENDING, WIN32_SERVICE_PAUSED.
The checkpoint value the service increments periodically to report its progress during a lengthy start, stop, pause, or continue operation. For example, the service should increment this value as it completes each step of its initialization when it is starting up.
The checkpoint is only valid when the status is one of WIN32_SERVICE_STOP_PENDING, WIN32_SERVICE_START_PENDING, WIN32_SERVICE_CONTINUE_PENDING or WIN32_SERVICE_PAUSE_PENDING.
Returns TRUE on success, FALSE if there is a problem with the parameters or a Win32 Error Code on failure.
So after much searching I finally found all the peices to make a working windows service & server including:
- Installing & Uninstalling the service
- Starting & Stopping the Service
- Actually running a basic Server
- Responding to windows Service to Stop/Start/Restart
I hope you find this useful! I did this using PHP 5.2 and the PECL library for 5.2 (PHP 5.3 at the time does not have a PECL Library compiled for it)

$max = 20; //Maximum Clients
//Exit if no start-up argument is passed
if (!isset($argv[1])){ShowHelp(); exit;}
//Create Windows Service
if ($argv[1] == 'install') {
$x = win32_create_service(array(
'service' => $Service,

debug_zval_dump($x);

On my Machine (Win XP SP2) the function "win32_get_last_control_message" never returns 4 so i will have to reply to 0 also.
finally after mixing several examples i now have a version working woithout filling my event log with errors:
