1. Database

Create a new database named "rss_feed", and import the SQL script in main folder, or copy/paste the script bellow:
    

  1. --
    2. 

  2. -- Table structure for table `post`
    3. 

  3. --
    4. 

  4.  
    5. 

  5. CREATE TABLE IF NOT EXISTS `post` (
    6. 

  6.   `id` int(11) NOT NULL AUTO_INCREMENT,
    7. 

  7.   `title` varchar(200) COLLATE utf8_unicode_ci NOT NULL,
    8. 

  8.   `link` varchar(200) COLLATE utf8_unicode_ci NOT NULL,
    9. 

  9.   `description` text COLLATE utf8_unicode_ci NOT NULL,
    10. 

  10.   PRIMARY KEY (`id`)
    11. 

  11. ) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=7 ;
    12. 

  12.  
    13.

3. Files

index.php

This is the main file, it will be displayed on the first view
    

  1. <!DOCTYPE html>
    2. 

  2. <html>
    3. 

  3. <head>
    4. 

  4.     <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

  9. <body>
    10. 

  10.     <div class="container">
    11. 

  11.         <h1 class="main_title">How to Create an RSS Feed with PHP and MySQL</h1>

  16. </body>
    17. 

  17. </html>
    18.

rss.php

The rss feed will be generated here. W’ll load the list of posts from the database using PHP PDO, and display this content as an xml file using the php header, header('Content-Type: application/xml');
    

  1. <?php
    2. 

  2. // PDO connect *********
    3. 

  3. function connect() {
    4. 

  4.     return new PDO('mysql:host=localhost;dbname=rss_feed', 'root', '', array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
    5. 

  5. }
    6. 

  6.  
    7. 

  7. $pdo = connect();
    8. 

  8.  
    9. 

  9. // posts *******************************
    10. 

  10. $sql = 'SELECT * FROM post ORDER BY id DESC';
    11. 

  11. $query = $pdo->prepare($sql);
    12. 

  12. $query->execute();
    13. 

  13. $rs_post = $query->fetchAll();
    14. 

  14.  
    15. 

  15. // The XML structure
    16. 

  16. $data = '<?xml version="1.0" encoding="UTF-8" ?>';
    17. 

  17. $data .= '<rss version="2.0">';
    18. 

  18. $data .= '<channel>';

    23. 

  23.     $data .= '<item>';
    24. 

  24.     $data .= '<title>'.$row['title'].'</title>';

    29. 

  29. $data .= '</channel>';
    30. 

  30. $data .= '</rss> ';
    31. 

  31.  
    32.
