CLXVII. win32service Functions

Introduction

The win32service extension is a Windows specific extension that allows PHP to communicate with the Service Control Manager to start, stop, register and unregister services, and even allows your PHP scripts to run as a service.

Requirements

Windows NT, Windows 2000, Windows XP or Windows Server 2003. Any version of windows derived from Windows NT should be compatible.

Installation

Installing from PECL

You can download php_win32service.dll from http://snaps.php.net/win32/. Choose the PECL_X_X folder that matches you PHP version.
Copy the php_win32service.dll into your extension_dir.
Load the extension from your php.ini
extension=php_win32service.dll

Examples

Example 1. Registering a PHP script to run as a service

<?php
win32_create_service(array(
		'service' => 'dummyphp',                 # the name of your service
		'display' => 'sample dummy PHP service', # description
		'params' => 'c:\path\to\script.php run', # path to the script and parameters
	));
?>

Example 2. Unregistering a service

<?php
win32_delete_service('dummyphp');
?>

Example 3. Running as a service

<?php
if ($argv[1] == 'run') {
  win32_start_service_ctrl_dispatcher('dummyphp');

  while (WIN32_SERVICE_CONTROL_STOP != win32_get_last_control_message()) {
    # do your work here.
    # try not to take up more than 30 seconds before going around the loop
    # again
  }
}
?>
