It took me a few nights to write a message board for a beginner to learn about PHP.
P.s. My space does not support PHP and does not support T_T demonstration.
Database structure: (Database Name: lyb)
Table 1: admin
Field: id (int11) name (varchvr) password (varchvr)
Table 2: lo
Field: id (int11) username (varchvr) sex (varchvr) qq (varchvr) email (varchvr) info (text) ip (varchvr) submit_time (datetime)
1 conn. php (connect to the database file)
<? Php
Mysql_connect ("localhost", "root", ""); // connect to the database
Mysql_select_db ("lyb"); // select a database
?>
2 header. php (Public header file)
Copy codeThe Code is as follows:

3 footer. php (Public bottom file)
Copy codeThe Code is as follows:

$ Num + = 1;
Print "<div id = \" footer \ "> Silver Message Board Version 1.0". "$ num". "bored silver </div> ";
Exec ("rm-rf $ counterFile ");

Exec ("echo 0> $ counterFile ");
}
DisplayCounter ($ counterFile );
?>
</Body>
</Html>
4 index. php (home page)
Copy codeThe Code is as follows:
<? Php

$ Rs = mysql_query ("select count (*) from lo"); // retrieves the total number of records and calculates the total number of pages.
$ Myrow = mysql_fetch_array ($ rs );
$ Numrows = $ myrow [0]; // calculates the total number of records.
$ Pages = intval ($ numrows/$ pagesize );
If ($ numrows % $ pagesize) $ pages ++; // you can specify the number of pages.
If (isset ($ _ GET ['page'])
{
$ Page = intval ($ _ GET ['page']);
}
Else
{
$ Page = 1; // set it to the first page
}

// The paging code ends.
