Today, we have written a PHP long article paging function for you to easily compile your code:

1. <? Php
2. Function ff_page ($ content, $ page)
3. {
4. Global $ expert_id;
5. $ PageLength = 2000; // Number of words per page
6. $ CLength = strlen ($ content );
7. $ PageCount = floor ($ CLength
   /$ PageLength) + 1; // calculate the page number
8. $ PageArray = array ();
9. $ Seperator = array ("n ",
   "R ",". ","! ","? ",";
   "," "," '"); // Separator
10. // Echo "page number:". $ PageCount. "<br> ";
11. // Echo "length:". $ CLength. "<br> ";
12. // The strpos () function returns a string in
    Position of the first occurrence of another string
13. If ($ CLength <$ PageLength)
14. {
15. Echo $ content;
16. } Else {
17. $ PageArray [0] = 0;
18. $ Pos = 0;

24. $ Pos = strpos ($ content,
    $ Seperator [$ j], $ PageArray [$ I] + 1900 );
25. While ($ Pos> 0 & $ Pos
    <($ I + 1) * $ PageLength &&
    $ Pos> $ I * $ PageLength)

Use of paging functions for PHP long articles

 
 

  
  
<? Php
  
  
$ Content1 = ''test text,
Try to be longer, www.corange.cn ";
  
  
$ Current = $ _ REQUEST ['page _ t'];
  
  
$ Result = ff_page
($ Content1, $ current );
  
  
Echo $ result;
  
  
?>
 
 

The code example for the use and implementation of the paging function in PHP is shown above.

Why :? Php functionff_page ($ content, $ page) {global $ expert_id; $ PageLength = 2000; // word per page...
