win32_start_service_ctrl_dispatcher

(PECL win32service SVN)

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

Description

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.

Parameters

name

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.

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
}
?>

Insert value of params between " if the string have a space:

<?php
// First you need to create a service, you only need to do this once
/*
win32_create_service(array(
    'service' => 'myphpservice',
    'display' => 'My PHP Service',
    'params' => '"c:\\my folder\myphpservice.php"',
    'path' => 'c:\\PHP\\php.exe'));

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.
