Solution: Use the template replacement technology (no time delay)
| The code is as follows: |
Copy code |
/*
| ------------------
| <Www.111cn.net>
| ------------------
*/
$ Users = $ _ POST ['users']; // add operation
If ($ region = 'ADD ')
{
$ Title = $ _ POST ['title'];
$ Content = $ _ POST ['content'];
// If you strictly follow MVC, the model should be called here
$ 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 static files
$ 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 in append mode
// 3. Read cyclically
// If the last part of the file is not read, read it all the time.
While (! Feof ($ fp ))
{
// Read a row
$ Row = fgets ($ fp );
// Replace the placeholder => You can define a complete replacement rule function.
$ Row = str_replace ('% title %', $ title, $ row); // if $ row is not assigned again, the $ row value will not change.
$ Row = str_replace ('% content %', $ content, $ row );
Fwrite ($ html_fp, $ row); // 4. Write the content to a static file
} // 5. The file must be closed
Fclose ($ html_fp );
Fclose ($ fp );
Echo "added successfully. <A href = 'newslist. Php'> Click to view the news! </A> ";
}
Else
{
Die ('add failed! ');
}
}
// Click the link to view details in the news list. You can change it to the generated static page address to directly access the static file. // News. tpl template file
/*
<Html>
<Head>
<Meta charset = "UTF-8"/>
<Title> % title % </title>
</Head>
<Body>
<H1> % title % <Pre> % content % </pre>
</Body>
</Html>

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: |
Copy code |
/*
| ------------------
| <Www.111cn.net>
| ------------------
*/
Header ('content-type: text/html; charset = utf-8 ');
$ Id = $ _ GET ['id']? Intval ($ _ GET ['id']): '';
If ($ id = '') die ('Enter the news id 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 here
$ 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 '<table style = "border: 1px solid red;" cellspacing = "0" width = "400px" height = "200px"> ';
Echo '<tr> <td> problem details </td> </tr> ';
Echo "<tr> <td> title: {$ row ['question _ title']} </td> </tr> ";
Echo "<tr> <td> Details: {$ row ['question _ detail ']} </td> </tr> ";
Echo '</table> ';
$ Ob_str = ob_get_contents ();
// 3. Save ob_str to a static file page. Take note of the file name: 1. Unique identification of the News 2. Conducive to seo
File_put_contents ("news-id-". $ id. ". html", $ ob_str );
// Close the database connection (not required; if the connection is not persistent, the database will be closed automatically after the script is executed)
Mysql_close ($ con );
} Else {
Echo 'no resource found! ';
} |
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.
