Overview:
This design allows you to design a count analysis program based on this counter to analyze page access and ip address access times and form a report.
I. database design
The database uses mysql
Related Files: createDatabase. SQL create a 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 id. the default value is the 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 ID
Count Int (10) number of visits from this ip address
Date datetime recent access time
Pages text previously accessed page IDs, separated by '|'
II. Detailed description:
1. you can count each page, or count the number of visits to each ip address, the last visit time, and the two tables required for each visit;
2. Count website visits: Set a website id in tpCounter [pagename = '0' flag is recommended];
3. check the session when you open the page. if the user's session does not exist, it indicates that the user has just started accessing the website. at this time, create a session for the user and increase the website count by 1, increase the number of Accessed pages by 1. [when you open or refresh the page] if the user's session already exists, the website count value does not increase, but the page count value increases by 1 for each refresh;
4. when the page is closed, check whether the number of pages opened by the user is 0. If yes, the user's session is destroyed; otherwise, the user's session is not destroyed. [no program is required for this function, automatic server execution]
5. if the page is not identified in tpCounter during access, a record is automatically inserted into the table;
6. pages is a text type that records the access time and Page accessed by the browser, including strings in a format similar to this:
| 16:00:00 | 1 | 12 | 5 | 4 | 9 |
It indicates that this ip address has accessed pages 1, 12, and 5 at 16:00:00, and accessed pages 5, 4, and 9 at [the page number is obtained from the previous table];
7. design the counting file (. php). every page contains this file, which includes the following functions:
1> session check,
2> connect to the database,
3> count [the parameter is the page name, ip address, and current time],
4> read and write databases,
5> disconnect from the database;
8. use the following method to record the Accessed page:
When a user opens a new page, if the user session does not exist, write the time and record the current page. If yes, write the current page. Write is appended.
9. The website count is in this header file, and the page count is in the counted page.
10. when a page contains this file, if you want to count the page, you must use the variable $ page_name before it is included, and assign a value to the page name. The page name cannot be repeated.
III. Interface description:
Related Files: counter. php
1/Boolean check_session ()
Function description: session check. true is returned for existence; false is returned for absence, and a Boolean variable existing is created and registered.
Entry parameter: None
Exit parameter: Boolean
2/site_count ($ content)
Function description: website access count
Entry parameter: database connection
Exit parameter: count value
3/page_count ($ connect, $ page_name, $ flag = true)
Function description: page count, number of page visits returned, integer type, $ flag indicates whether to increase the count. the default value is true.
Entry parameter: $ connect: database connection, $ page_name: webpage name
Exit parameter: Page access count
4/show_site_count (int type)
Function description: Display count
Entry parameter: type = 1
Type = 2 use text count
IV. process
0/check the permissions on the page
Because the header file can be compiled only by reference, you must check whether the file is referenced or directly browsed.
1. connect to the database
2. check the session. if the session does not exist, create the session and count the website.
3/display count
4/count pages
5. disconnect from the database [automatically implemented]
5. usage
All functions are included in a header file. you can include this header file when using this function.
