Solution: Use the template replacement technology (no time delay). The code is as follows:

/* | ---------------- |
 
  
| ---------------- */$ Response = $ _ POST ['unknown']; // add operation if ($ response = 'ADD ') {$ title = $ _ POST ['title']; $ content = $ _ POST ['content']; // If you strictly follow MVC, here we should call model $ con = mysql_connect ('localhost', 'root', '123'); if (! $ Con) {die ('connection failed! ');} Mysql_select_db ('news', $ con); $ SQL = "insert into question (null,' $ title', '$ content ','')"; if (mysql_query ($ SQL, $ con) {// 1. generate a static file $ id = mysql_insert_id (); $ html_filename = 'news-id'.$id.'html '; $ html_fp = fopen ($ html_filename, 'w'); // 2.read the template file (news.html) $ fp = fopen ('news. tpl ', 'r'); // r read-only mode; r + read/write mode; w write mode: file content will be cleared! If the file does not exist, it will be created; a will be opened as an append // 3. read the file cyclically // if the last part of the file is not read, it will always read while (! Feof ($ fp) {// read a row $ row = fgets ($ fp ); // replace the placeholder => you can customize the complete replacement rule function $ row = str_replace ('% title %', $ title, $ row ); // if $ row is not re-assigned, the $ row value will not change $ row = str_replace ('% content %', $ content, $ row); fwrite ($ html_fp, $ row); // 4. write content to a static file} // 5. the file must be closed fclose ($ html_fp); fclose ($ fp); echo "added successfully. Click to view news! ";} Else {die ('failed to add! ') ;}} In the news list, click the link to view details. you can change it to the generated static page address to directly access the static file. the code is as follows:    
    
  % Title %    % Title %
  
%content%
    Solution: If a static file exists and is generated within 30 seconds, the static page is directly returned (with time delay). The code is as follows:/* | ---------------- |
  
   
| ---------------- */Header ('content-type: text/html; charset = utf-8 '); $ id = $ _ GET ['id']? Intval ($ _ GET ['id']): ''; if ($ id ='') die ('Enter the id of the news you want to query! '); $ Html_file = "news-id -". $ id. ". html "; // 1. main code: if (file_exists ($ html_file) & filemtime ($ html_file) + 30> = time () {echo 'static page: '; echo file_get_contents ($ html_file ); exit;} // You can also use the DB Tool class $ con = mysql_connect ('localhost', 'root', '123'); if (! $ Con) {die ('connection failed! ');} Mysql_select_db ('testdb', $ con); $ SQL = "select * from bo_question where question_id = $ id"; $ res = mysql_query ($ SQL, $ con); if ($ row = mysql_fetch_assoc ($ res) {ob_start (); // 2. start ob cache header ('content-type: text/html; charset = utf-8 '); echo'
   '; Echo'
   
 
  
    
'; Echo'
    
  '; Echo" 
   "; Echo" 
   "; Echo' 
  
 
   
 
    
Problem Details
 
   
 
    
Title: {$ row ['question _ title']}
 
   
 
    
Details: {$ row ['question _ detail ']}
 
   
   
 
'; $ Ob_str = ob_get_contents (); // 3. save the ob_str file to a static file page. the file name must be: 1. uniquely identifies the News 2. seo file_put_contents ("news-id -". $ id. ". html ", $ ob_str); // closes the database connection (not required; otherwise, the database is automatically closed after the script is executed) mysql_close ($ con );} no resources found in else {echo! ';}
  
 

From the above, we can see that the first method for generating static pages is more suitable for post-page maintenance. The latter is difficult to maintain. we recommend the first method.
