The end stage after the request: Rshutdown: This page request completed, or by the user to Die (exit), then PHP will start the Recycle program, recycling the resources used for this request. This time, all the Rshutdown (commonly called request Shutdown) methods that have been loaded are executed, and the extension can take advantage of a list of variables in the kernel, among other things. As soon as PHP exec

ASP. NET MVC Request Life CycleWhile programming with ASP. NET MVC, you should is aware of the life's an ASP. NET MVC request from birth to death. In this article, I am going to expose the ASP Request life cycle. There is seven main steps that happen if you do a request to an ASP. Web applications. For more details refer detailed ASP. NET MVC Pipeline Routing

You rewrite the activity of several life cycle methods, run to know what is going on, really lazy people can see: Click to open the link.OnCreate: Executes when the activity is created and executes only once.OnStart: Executes when the interface is visible.Onresume: The interface gets the focus, and the button executes when it is clicked.OnPause: The interface loses focus and the button does not click.OnStop

Every Android developer should know that the Android system has four important basic components: activity (Active), service (services), broadcast receive (broadcast receiver), and content Provider (contents provider , where activity is the most important component, open the app on your phone, all you can see is activity, and here are a few questions about the activity life cycle.1 8 callback functions for t

In the previous article, the scope,scope of the bean in spring is not only the way beans exist in the spring container, such as prototype and Singleton, but also some of the properties that exist in the period, such as session and request. In spring, beans are instantiated from the dependency injection to the initialization, to the last extinction, and to the complete life cycle. Together with scope, it for
