, when used locally, in a browser does not seem to create a new session, you need to login in different browsers to see the effect.It is also important to note that when exiting the chat room, the application key is "nickname", that is, the value of the current session["nickname") is removed. Otherwise, when you refresh the listbox, you will find that the nickname for the exit is still present.Also the key to "count" of the Application Object-1, perhaps you have to ask, is not in the Session_End

One, click Count The general statistical approach is to provide a set of interfaces that need to be embedded in the code. When the program needs to access the interface, the background can be statistical information. Statistical methods:1. Platform SDK provides 3 interface Start\stop\pause, game start when the server opened session and recorded a start time, the game STOP time to calculate the time again, by calculating the time interval accumulated to a certain amount to calculate a valid g

There is nothing to do today, want to show the number of online blog statistics. Look for many examples on the Internet, not database storage data is file storage, the code also looks too complex. After the evening came back, conceived the next, see my server installed Memcache service, why not use Memcache realize it. Here is the implementation process: Effect Chart: Implementation code:

This article mainly introduces the creation, destruction, logon information Session variable setting of the listener listening through the servlet, which is used to realize the online user statistics.

This is a very accurate, through PHP to achieve statistics online number of methods, want to know how to achieve the patience to read. Hopefully this article will help you learn about PHP programming.

There are three methods to prevent repeated online statistics: 1. Use Database records 2. Use ServletContext-type application 3. Use session.The first approach is relatively simple, but it will cause a burden on the database. The second approach has not been implemented yet .:)This article implements the practice of using sessions. The basic idea is to create a session record login name during normal login,

Php provides detailed online time statistics for users. For more information, see. First, we will introduce the structure of the involved data table, with four fields: The code is as follows: The code is as follows: Uid : User ID Session_id : Session_id generated by the system after the user logs on, which is obtained by using the session_id () function in PHP. Login_time : Logo

we generally understand to place a session or destroy a session, which is the function of monitoring, Because the syntax for placing sessions in the servlet is Session.setattribute ("Session name", the object to put in). and session listening, listening to the HTTP connection, as long as there is a user connected to the server, even if the connection is a blank JSP page, will also trigger the sessions event, so here is the connection actually refers to the The most appropriate time to count the

application| Statistics | original | online | The most common method is to use the session, but the disadvantage is that there is no immediate response online (there is a time-out) and Occupy server resources (if 100 people online there are 100 sessions, think about 8) Last time (seems to be a long time) introduced a m

This article mainly introduces the code for counting the number of online website users implemented by php + memcache. The code example is concise and practical. If you need a friend, you can refer to the following: I want to show the number of online users in blog statistics.
