win32_start_service_ctrl_dispatcher — Registers the script with the SCM, so that it can act as the service with the given name
$name
, bool $gracefulMode = true
) : voidWhen 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.
Since version 0.2.0, this function work only in "cli" SAPI. On other SAPI this function is disabled.
nameThe short-name of the service, as registered by win32_create_service().
gracefulMode
true for exit graceful. false for exit with error. See
win32_set_service_exit_mode() for more details.
Prior to version 1.0.0, if the SAPI is not "cli", this function emits an
E_ERROR level error.
As of version 1.0.0, will throw a
Win32ServiceException if SAPI is not
"cli"
示例 #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
}
?>
