checkpoint

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.

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:

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)

<?php
    //Service Settings
    $Service = 'MyServiceFinal';
    $Display = 'My PHP Service';
    
    //Server Settings
    $host = '127.0.0.1';        //Bind to IP #
    $port = 23;                            //On port #
    $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,
        'display' => $Service,
        'params' => __file__ . ' run',
        'path' => 'c:\\php\\php.exe',
    ));
    debug_zval_dump($x);
    echo "Service Installed\n\n";
    exit;
    
  //Remove Windows Service
    } else if ($argv[1] == 'uninstall') {
        $x = win32_delete_service($Service);
        debug_zval_dump($x);
        echo "Service Removed\n\n";
        exit;
    
  //Start Windows Service
    } elseif($argv[1] == "start") {
      $x = win32_start_service($Service);
      debug_zval_dump($x);
      echo "Service Started\n\n";
      exit;
      
    //Stop Windows Service
    } elseif($argv[1] == "stop") {
      $x = win32_stop_service($Service);
      debug_zval_dump($x);
      echo "Service Stopped\n\n";
      exit;
      
    //Unkown Command
    } else if ($argv[1] != 'run') {
        ShowHelp(); exit();
    }

//Tell windows the service has started...
if (!win32_start_service_ctrl_dispatcher($Service)) die("Could not connect to service : $Service");
win32_set_service_status(WIN32_SERVICE_RUNNING);

// No timeouts, flush content immediatly
set_time_limit(0);
ob_implicit_flush();

//Server Loop
while (1) {
    usleep(500);
    
    //Handle Windows Service Request
    switch (win32_get_last_control_message()) {
        case WIN32_SERVICE_CONTROL_CONTINUE: break; // Continue server routine
        case WIN32_SERVICE_CONTROL_INTERROGATE: win32_set_service_status(WIN32_NO_ERROR); break; // Respond with status
        case WIN32_SERVICE_CONTROL_STOP: win32_set_service_status(WIN32_SERVICE_STOPPED); exit; // Terminate script
        default: win32_set_service_status(WIN32_ERROR_CALL_NOT_IMPLEMENTED); // Add more cases to handle other service calls
    }
    //Acutal Server Code

}

//Clean up and Exit
win32_set_service_status(WIN32_SERVICE_STOPPED);
exit;

//*************** FUNCTIONS ***************
function ShowHelp(){
    echo "Usage:
