As for webpage paging, I first learned how to make the title output by page. what I want to ask is how to implement paging with an article, that is, to output a fixed number of words per page.

This is the page I have referenced. it is divided by title.
Include "config/db_mysql.php ";
$ Pagesize = 8; // defines how many records are displayed on each page
$ Page = isset ($ _ GET ["page"])? Intval ($ _ GET ["page"]): 1; // defines the initial page Value. if the page passed by get is empty, page = 1,
$ Total = mysql_num_rows (mysql_query ("select id from news"); // execute the query to obtain the total number of records
$ Pagecount = ceil ($ total/$ pagesize); // calculate the total number of pages
If ($ page> $ pagecount ){
$ Page = $ pagecount; // Check the submitted page.
}
If ($ page <= 0 ){


$ Page = 1; // Check the submitted page.
}
$ Offset = ($ page-1) * $ pagesize; // offset
$ Pre = $ page-1; // Previous page
$ Next = $ page + 1; // next page
$ First = 1; // page 1
$ Last = $ pagecount; // last Page
$ SQL = "select * from 'news' order by id desc limit $ offset, $ pagesize"; // execute the query
$ Result = mysql_query ($ SQL );
While ($ arrn = mysql_fetch_array ($ result ))
{
Echo "". "". $ arrn ['title']. "". "";
Echo "". "". $ arrn ['Time']. "". "";
Echo"
";
Echo"
";

}
?> Home Page> Previous Page> Next Page> last page
I tried to rewrite the code if I wanted to change the value of $ total so that I could output it by page.


So we made the following changes:
$ Id = $ _ POST ["id"];
$ SQL = "select * from 'news' where id = $ id ";
$ Result = mysql_query ($ SQL );
While (mysql_fetch_query ($ result ))
{
$ Total = strlen ($ arrn ['content']); // obtain the total number of articles. However, if there is a problem, the Chinese character occupies two characters, therefore, the output is always a matter of two times.
}

$ Pagesize = 8; // defines how many records are displayed on each page
$ Page = isset ($ _ GET ["page"])? Intval ($ _ GET ["page"]): 1; // defines the initial page Value. if the page passed by get is empty, page = 1,
$ Total = mysql_num_rows (mysql_query ("select id from news"); // execute the query to obtain the total number of records
$ Pagecount = ceil ($ total/$ pagesize); // calculate the total number of pages
If ($ page> $ pagecount ){
$ Page = $ pagecount; // Check the submitted page.
}
If ($ page <= 0 ){


$ Page = 1; // Check the submitted page.
}
$ Offset = ($ page-1) * $ pagesize; // offset
$ Pre = $ page-1; // Previous page
$ Next = $ page + 1; // next page
$ First = 1; // page 1
$ Last = $ pagecount; // last Page
$ SQL = "select * from 'news' order by id desc limit $ offset, $ pagesize"; // execute the query
$ Result = mysql_query ($ SQL );
While ($ arrn = mysql_fetch_array ($ result ))
{
Echo $ arrn ['content'];

}
?> Home Page> Previous Page> Next Page> last page
There will be something on the first page, and it will become a jump, and this page cannot be displayed


------ Solution --------------------
Pagination is a page that is manually inserted by the person who entered the article into the code using regular expressions.
------ Solution --------------------
It should be because a paging character is inserted in the article, and JS can be used in the client for paging.
