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

说明

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.

参数

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

返回值

成功, 参数错误时返回 FALSE , 或失败时返回一个 Win32 错误码 . 时返回 TRUE

范例

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.
