Counter detailed design_PHP tutorial

Overview:
This design can design a counting analysis program based on this counter, which can analyze the number of page visits and IP visits, and form a report.
1. Database design
The database uses mysql
Related files: createDatabase.sql Create database
createTblCounter.sql Create counter table


Table name: tpCounter (table of pages counter)
field:
Name Type Meaning
id Int (10) auto_increment Serial number
pagename varchar(20) Page identification, the default is page file name
count Int(10) Count Value

Table name: tiCounter (table of ip counter)
Field:
Name Type Meaning
id Int(10) auto_increment Serial number
ip varchar(20) Ip identification
count Int(10) The number of times the IP has been visited
date datetime The most recent access time
pages text The page IDs that have been visited, separated by '|'

2. Detailed description:
1. You can count each page, or you can count the number of visits to each IP, the most recent visit time, and the pages visited each time. Two tables are needed;
2. Count the number of website visitors: Set one in tpCounter Site identification [it is recommended to use the pagename='0' flag];
3. Check the session every time you open the page. If the user's session does not exist, it means that you have just started to visit this website. Create a user at this time session, the website count increases by 1, and the visited page count increases by 1; [when opening or refreshing the page] If the user session already exists, the website count value does not increase, but the page count value increases by 1 every time it is refreshed;
4. When closing the page, check whether the number of pages the user has opened on this website is 0. If so, destroy the user's session, otherwise it will not be destroyed; [This function does not require writing a program, the server automatically executes it]
5. If the page is not identified in tpCounter during the visit, a record will be automatically inserted into the table;
6. Pages is a text type that records the time the viewer visited and the page visited, which contains a string in a format similar to this:
||2001-5-1 16:00:00|1|12|5||2001-8-3 10:12:5|4|9|
means that this ip is in 2001-5-1 Visited pages 1, 12, and 5 at 16:00:00, and visited pages 5, 4, and 9 at 2001-8-3 10:12:5 [the page number is obtained from the previous table];
7, Design the counting file (.php). Each page contains this file. This file contains the following functions:
1>session check,
2>connect to the database,
3>Count [parameters are Page name, IP, current time],
4> Read and write the database,
5> Disconnect from the database;
8. The visited pages are recorded in the following way:
User When opening a new page, if the user session does not exist, write the time and record the current page. If it exists, write the current page. Writing is done in an appended manner.
9. The website count is in this header file, and the page count is in the counted pages.
10. When each page includes this file, if you want to count the pages, you must use the variable $page_name before including it, and assign it to the name of the page. Page names cannot be repeated.

3. Interface description:
Related files: counter.php

1/Boolean check_session()
Function description: session check, return true if it exists; return true if it does not exist false, and create and register the Boolean variable existing
Entry parameters: None
Exit parameters: Boolean
2/site_count($content)
Function description: Website visit count
Entry parameters : Database connection
Exit parameters: Count value

3/page_count($connect,$page_name,$flag=true)
Function description: Count of web pages, return the number of page visits, integer, $ flag is a flag indicating whether to increase the count, the default is true
Entry parameters: $connect: database connection, $page_name: web page name
Exit parameters: number of page visits


4/show_site_count( int type)
Function description: Display count
Entry parameters: type==1 uses graphic counting
type==2 uses text counting

4. Process
0/check entry Permissions of the page
Since the header file needs to be compiled by reference, it must be checked whether it is passed by reference or browsed directly
1/Link to the database
2/Check the session, if it does not exist, create the session and count the website
3/Display count
4/Perform page count
5/Disconnect from the database [automatic implementation]

5. Usage
All functions are included in one In the header file, when using it, just include this header file.
6. Attached source program

* Description: counter file, can count the entire website,
* can count all pages, can count each ip
*/
/**Interface implementation function:
* 1>session check
* 2>Connect to database
* 3>Count
* 4>Read and write database
* 5>Table output of link part

* This file must be included in other php files.
* You need to configure the $inc variable before quoting.
