win32_start_service_ctrl_dispatcherRegisters the script with the SCM, so that it can act as the service with the given name


mixed win32_start_service_ctrl_dispatcher ( string $name )

When launched via the Service Control Manager, a service process is required to "check-in" with it to establish service monitoring and communication facilities. This function performs the check-in by spawning a thread to handle the lower-level communication with the service control manager.

Once started, the service process should do 2 things. The first is to tell the Service Control Manager that the service is running. This is achieved by calling win32_set_service_status() with the WIN32_SERVICE_RUNNING constant. If you need to perform some lengthy process before the service is actually running, then you can use the WIN32_SERVICE_START_PENDING constant. The second is to continue to check-in with the service control manager so that it can determine if it should terminate. This is achieved by periodically calling win32_get_last_control_message() and handling the return code appropriately.



The short-name of the service, as registered by win32_create_service().

Return Values

Returns TRUE on success, FALSE if there is a problem with the parameters or a Win32 Error Code on failure.


Example #1 A win32_start_service_ctrl_dispatcher() example

Check if the service is runnig under the SCM.

if (!win32_start_service_ctrl_dispatcher('dummyphp')) {
"I'm probably not running under the service control manager");


// Some lengthy process to get this service up and running.


while (
WIN32_SERVICE_CONTROL_STOP != win32_get_last_control_message()) {
# do some work here, trying not to take more than around 30 seconds
  # before coming back into the loop again
