This function is used for writing rss to a file.

<?php

$rss = simplexml_load_file($url);

if($rss){
$text = "";

$text .= $rss->channel->title."\r\n \r\n \r\n";

$items = $rss->channel->item;

foreach($items as $item){
$title = $item->title;
$link = $item->link;
$published_on = $item->pubDate;
$description = $item->description;

$text .= $title."\r\n";
$text .= $published_on."\r\n";
$text .= $description."\r\n \r\n";
}

$handle = fopen($file, 'w');
fwrite($handle, $text);
fclose($handle);
}

return false;
}

$url = "http://rubensargsyan.wordpress.com/feed/"; // Rss url
