How to create rss feeds using php and mysql

In this post i want to explain how to create rss feeds using php code and get the data from mysql table. It is very simple to develop and use.

Step 1 : Connect to database

We already discussed about how to connect database using php code.See the following code to connect database:

<?php
DEFINE ('DB_USER', 'root');
DEFINE ('DB_PASSWORD', 'root');
DEFINE ('DB_HOST', 'localhost');
DEFINE ('DB_NAME', 'rss');

// Make the connnection and then select the database.
$dbc = @mysql_connect (DB_HOST, DB_USER, DB_PASSWORD) OR die ('Could not connect to MySQL: ' . mysql_error() );
mysql_select_db (DB_NAME) OR die ('Could not select the database: ' . mysql_error() );
?>

By using about code we can connect to database sucessfully.

<?php

class RSS
{
public function RSS()
{
require_once ('mysql_connect.php');
}

public function GetFeed()
{
return $this->getDetails() . $this->getItems();
}

private function dbConnect()
{
DEFINE ('LINK', mysql_connect (DB_HOST, DB_USER, DB_PASSWORD));
}

private function getDetails()
{
$detailsTable = "webref_rss_details";
$this->dbConnect($detailsTable);
$query = "SELECT * FROM ". $detailsTable;
$result = mysql_db_query (DB_NAME, $query, LINK);

while($row = mysql_fetch_array($result))
{
$details = '<?xml version="1.0" encoding="ISO-8859-1" ?>
<rss version="2.0">
<channel>
<title>'. $row['title'] .'</title>
<link>'. $row['link'] .'</link>
<description>'. $row['description'] .'</description>
<language>'. $row['language'] .'</language>
<image>
<title>'. $row['image_title'] .'</title>
<url>'. $row['image_url'] .'</url>
<link>'. $row['image_link'] .'</link>
<width>'. $row['image_width'] .'</width>
<height>'. $row['image_height'] .'</height>
</image>';
}
return $details;
}

private function getItems()
{
$itemsTable = "webref_rss_items";
$this->dbConnect($itemsTable);
$query = "SELECT * FROM ". $itemsTable;
$result = mysql_db_query (DB_NAME, $query, LINK);
$items = '';
while($row = mysql_fetch_array($result))
{
$items .= '<item>
<title>'. $row["title"] .'</title>
<link>'. $row["link"] .'</link>
<description><![CDATA['. $row["description"] .']]></description>
</item>';
}
$items .= '</channel>
</rss>';
return $items;
}

}

?>

By using about code we can create a class for rss feed.

Step3: Create a object to class and display rss feeds.

<?php
header("Content-Type: application/xml; charset=ISO-8859-1");
include("classes/RSS.class.php");
$rss = new RSS();
echo $rss->GetFeed();
?>

Hope that it will be useful.
