win32_start_service_ctrl_dispatcher
(PECL win32service SVN)
win32_start_service_ctrl_dispatcher — Registers the script with the SCM, so that it can act as the service with the given name
Description
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.
Return Values
Returns TRUE on success, FALSE if there is a problem with the parameters or a Win32 Error Code on failure.
Examples
Example #1 A win32_start_service_ctrl_dispatcher() example
Check if the service is runnig under the SCM.
<?php
if (!win32_start_service_ctrl_dispatcher('dummyphp')) {
die("I'm probably not running under the service control manager");
}
win32_set_service_status(WIN32_SERVICE_START_PENDING);
// Some lengthy process to get this service up and running.
win32_set_service_status(WIN32_SERVICE_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
}
?>

Don't try to call "win32_start_service_ctrl_dispatcher" too late in your code. You'd trigger a #2186 error : "The service is not responding to the control function." (from commande line) or a #1053 error : "The service did not respond to the start or control request in a timely fashion." (from services GUI).
Try not to load a bunch of PEAR classes before to register php script as Service like I did.
Another good hint, to get a verbose version of the return code, you can call "NET HELPMSG ###" from command line where ### is your error code.
