Phpcmf 框架 CMS 初始化事件：PC 和移动端自动跳转实现

This code is a hook function that is executed when the "cms_init" event is triggered in the "appname" application. The purpose of this code is to handle the redirection between PC and mobile versions of the website.\n\nThe function first checks if the user is accessing the website from a PC device using the \\Phpcmf\Service::IS_PC_USER() function. If the user is on a PC, it checks if the current template is a mobile template using the \\Phpcmf\Service::IS_MOBILE_TPL() function. If it is a mobile template, the function simply returns and does not perform any redirection.\n\nIf the user is not on a PC device, it means they are accessing the website from a mobile device. The function then loads a configuration file called "domain_client.php" which contains a mapping of PC domain names to corresponding mobile domain names. It then checks if the current template is a PC template using the \\Phpcmf\Service::IS_PC_TPL() function. If it is a PC template, it checks if the current domain is in the mapping array. If it is, it means that the current domain is a PC domain and needs to be redirected to the corresponding mobile domain. The function uses the \\Phpcmf\Service::L('Router')->auto_redirect() function to perform the redirection.\n\nOverall, this code handles the redirection between PC and mobile versions of the website based on the user's device and the current template being used.
