I'm trying to use Simplepie to filter a feed for items that match a regex keyword filter, and then use those items to create another feed. However, I'm having trouble moving the items from the $matches array into the rss block. I'm still rather a novice with PHP, so maybe I'm missing something obvious, but would appreciate the help.
<?php
$feed = new SimplePie();
$feed->set_feed_url('feed://stackoverflow.com/feeds');
$feed->init();
$feed->set_cache_duration (3600);
$feed->set_timeout(30);
$feed->handle_content_type();
$countItem = 0;
foreach ($feed->get_items() as $item):
$checktitle = $item->get_title();
//Regex keyword filter
$pattern = '/php/i';
//If the there is a keyword match, store in $matches array
if (preg_match($pattern, $checktitle)) {
$matches[$countItem]= $item;
$countItem++;
}
endforeach
?>
<?php if ($success) {
$itemlimit=0;
foreach($matches as $item) {
if ($itemlimit==20) { break; }
?>
//rss block
<item>
<title><?php $item->get_title()); ?></title>
<link><?php echo $item->get_permalink(); ?></link>
<pubDate><?php echo $item->get_date();></pubDate>
<description><![CDATA[<?php echo $item->get_description(); ?>]]></description>
<content:encoded><![CDATA[<?php $item->get_content(); ?>]]></content:encoded>
</item>
<?
$itemlimit = $itemlimit + 1;
}
}
?>
Is your $success being set somewhere? (You did ask if you were missing something obvious! :D)
Are you properly setting the headers, doctype, all that kind of stuff? You might want to use a framework or XML/RSS writer to build the responses, which will be a lot easier than building them manually.

I am adding an RSS feed to my website. I created the RSS.xml index file and next I want to display its contents in a nicely formatted way in a webpage.
Using PHP, I can do this:
$index = file_get_contents ($path . 'RSS.xml');
echo $index;
But all that does is dump the contents as a long stream of text with the tags removed.
I know that treating RSS.xml as a link, like this:
<a href="../blogs/RSS.xml">
<img src="../blogs/feed-icon-16.gif">Blog Index
</a>
causes my browser to parse and display it in a reasonable way when the user clicks on the link. However I want to embed it directly in the web page and not make the user go through another click.
What is the proper way to do what I want?
Use the following code:
include_once('Simple/autoloader.php');
$feed = new SimplePie();
$feed->set_feed_url($url);
$feed->enable_cache(false);
$feed->set_output_encoding('utf-8');
$feed->init();
$i=0;
$items = $feed->get_items();
foreach ($items as $item) {
$i++;
/*You are getting title,description,date of your rss by the following code*/
$title = $item->get_title();
$url = $item->get_permalink();
$desc = $item->get_description();
$date = $item->get_date();
}
Download the Simple folder data from : https://github.com/jewelhuq/Online-News-Grabber/tree/master/worldnews/Simple
Hope it will work for you. There $url mean your rss feed url. If you works then response.
Turns out, it's simple by using the PHP xml parer function:
$xml = simplexml_load_file ($path . 'RSS.xml');
$channel = $xml->channel;
$channel_title = $channel->title;
$channel_description = $channel->description;
echo "<h1>$channel_title</h1>";
echo "<h2>$channel_description</h2>";
foreach ($channel->item as $item)
{
$title = $item->title;
$link = $item->link;
$descr = $item->description;
echo "<h3><a href='$link'>$title</a></h3>";
echo "<p>$descr</p>";
}
I have this function to get title of a website:
function getTitle($Url){
$str = file_get_contents($Url);
if(strlen($str)>0){
preg_match("/\<title\>(.*)\<\/title\>/",$str,$title);
return $title[1];
}
}
However, this function make my page took too much time to response. Someone tell me to get title by request header of the website only, which won't read the whole file, but I don't know how. Can anyone please tell me which code and function i should use to do this? Thank you very much.
Using regex is not a good idea for HTML, use the DOM Parser instead
$html = new simple_html_dom();
$html->load_file('****'); //put url or filename
$title = $html->find('title');
echo $title->plaintext;
or
// Create DOM from URL or file
$html = file_get_html('*****');
// Find all images
foreach($html->find('title') as $element)
echo $element->src . '<br>';
Good read
RegEx match open tags except XHTML self-contained tags
Use jQuery Instead to get Title of your page
$(document).ready(function() {
alert($("title").text());
});
Demo : http://jsfiddle.net/WQNT8/1/
try this will work surely
include_once 'simple_html_dom.php';
$oHtml = str_get_html($url);
$Title = array_shift($oHtml->find('title'))->innertext;
$Description = array_shift($oHtml->find("meta[name='description']"))->content;
$keywords = array_shift($oHtml->find("meta[name='keywords']"))->content;
echo $title;
echo $Description;
echo $keywords;
I'm trying to read the xml information that tumblr provides to create a kind of news feed off the tumblr, but I'm very stuck.
<?php
$request_url = 'http://candybrie.tumblr.com/api/read?type=post&start=0&num=5&type=text';
$xml = simplexml_load_file($request_url);
if (!$xml)
{
exit('Failed to retrieve data.');
}
else
{
foreach ($xml->posts[0] AS $post)
{
$title = $post->{'regular-title'};
$post = $post->{'regular-body'};
$small_post = substr($post,0,320);
echo .$title.;
echo '<p>'.$small_post.'</p>';
}
}
?>
Which always breaks as soon as it tries to go through the nodes. So basically "tumblr->posts;....ect" is displayed on my html page.
I've tried saving the information as a local xml file. I've tried using different ways to create the simplexml object, like loading it as a string (probably a silly idea). I double checked that my webhosting was running PHP5. So basically, I'm stuck on why this wouldn't be working.
EDIT: Ok I tried changing from where I started (back to the original way it was, starting from tumblr was just another (actually silly) way to try to fix it. It still breaks right after the first ->, so displays "posts[0] AS $post....ect" on screen.
This is the first thing I've ever done in PHP so there might be something obvious that I should have set up beforehand or something. I don't know and couldn't find anything like that though.
This should work :
<?php
$request_url = 'http://candybrie.tumblr.com/api/read?type=post&start=0&num=5&type=text';
$xml = simplexml_load_file($request_url);
if ( !$xml ){
exit('Failed to retrieve data.');
}else{
foreach ( $xml->posts[0] AS $post){
$title = $post->{'regular-title'};
$post = $post->{'regular-body'};
$small_post = substr($post,0,320);
echo $title;
echo '<p>'.$small_post.'</p>';
echo '<hr>';
}
}
First thing in you code is that you used root element that should not be used.
<?php
$request_url = 'http://candybrie.tumblr.com/api/read?type=post&start=0&num=5&type=text';
$xml = simplexml_load_file($request_url);
if (!$xml)
{
exit('Failed to retrieve data.');
}
else
{
foreach ($xml->posts->post as $post)
{
$title = $post->{'regular-title'};
$post = $post->{'regular-body'};
$small_post = substr($post,0,320);
echo .$title.;
echo '<p>'.$small_post.'</p>';
}
}
?>
$xml->posts returns you the posts nodes, so if you want to iterate the post nodes you should try $xml->posts->post, which gives you the ability to iterate through the post nodes inside the first posts node.
Also as Needhi pointed out you shouldn't pass through the root node (tumblr), because $xml represents itself the root node. (So I fixed my answer).
I have been researching this topic for a few days now and i'm still non the wiser as on how to do it.
I want to get an RSS feed from forexfactory.com to my website, i want to do some formatting on whats happening and i also want the latest information from them (Although those last two points can wait as long as i have some more or feed running).
Preferably I'd like to develop this from the ground up if anyone knows of a tutorial or something i could use?
If not i will settle for using a third party API or something like that as long as i get to do some of the work.
I'm not sure what it is but there is something about RSS that i'm not getting so if anyone knows of any good, probably basic tutorials that would help me out a lot. It's kind of hard going through page after page of google searches.
Also i'm not to fussed on the language it's outputted in Javascript, PHP or HTML will be great though.
Thanks for the help.
It looks like SimplePie may be what you are looking for. It's a very basic RSS plugin which is quite easy to use and is customisable too. You can download it from the website.
You can use it at it's bare bones or you can delve deeper in to the plugin if you wish. Here's a demo on their website.
index.php
include('rss_class.php');
$feedlist = new rss($feed_url);
echo $feedlist->display(2,"Feed Title");
rss_class.php
<?php
class rss {
var $feed;
function rss($feed){
$this->feed = $feed;
}
function parse(){
$rss = simplexml_load_file($this->feed);
//print_r($rss);die; /// Check here for attributes
$rss_split = array();
foreach ($rss->channel->item as $item) {
$title = (string) $item->title;
$link = (string) $item->link;
$pubDate = (string) $item->pubDate;
$description = (string) $item->description;
$image = $rss->channel->item->enclosure->attributes();
$image_url = $image['url'];
$rss_split[] = '
<li>
<h5>'.$title.'</h5>
<span class="dateWrap">'.$pubDate.'</span>
<p>'.$description.'</p>
Read Full Story
</li>
';
}
return $rss_split;
}
function display($numrows,$head){
$rss_split = $this->parse();
$i = 0;
$rss_data = '<h2>'.$head.'</h2><ul class="newsBlock">';
while($i<$numrows){
$rss_data .= $rss_split[$i];
$i++;
}
$trim = str_replace('', '',$this->feed);
$user = str_replace('&lang=en-us&format=rss_200','',$trim);
$rss_data.='</ul>';
return $rss_data;
}
}
?>
I didn't incorporate the < TABLE > tags as there might be more than one article that you would like to display.
class RssFeed
{
public $rss = "";
public function __construct($article)
{
$this->rss = simplexml_load_file($article, 'SimpleXMLElement', LIBXML_NOERROR | LIBXML_NOWARNING);
if($this->rss != false)
{
printf("<TR>\r\n");
printf("<TD>\r\n");
printf("<h3>%s</h3>\r\n", $this->rss->channel->title);
printf("</TD></TR>\r\n");
foreach($this->rss->channel->item as $value)
{
printf("<TR>\r\n");
printf("<TD id=\"feedmiddletd\">\r\n");
printf("<A target=\"_blank\" HREF=\"%s\">%s</A><BR/>\r\n", $value->link, $value->title);
printf($value->description);
printf("</TD></TR>\r\n");
}
}
}
}
I'm making RSS feed reader with PHP and i get all feed content, but i can't figure out hot to target RSS values so i can echo them, style them, etc!
this is the feed
my script so far:
foreach($feed_list as $from => $feeds) {
$xml = simplexml_load_file($feeds);
echo "<pre>";
print_r($xml);
echo "</pre>";
}
I get this out after code executes
Sorry for trouble, but i found out how
<?php
$rss = simplexml_load_file('http://www.riga.lv/rss/lv/PressRelease/');
?>
<h1><?php echo $rss->channel->title; ?></h1>
<ul>
<?php
foreach($rss->channel->item as $e) {
echo "<li><a href=\"".$e->link['href']."\">";
echo $e->title;
echo "</a></li>\n";
}
?>
Thanks to this :) - Thanks Stack Overflow :)
You need to traverse the $xml object returned and get the values for each single node... check http://www.php.net/manual/en/class.simplexmlelement.php for more info.
