1. Limit the Number of Headlines(aka Items) Returned.
- -Problem:
- -You want to display the 10 (or 3 or whatever) most recent headlines, but the RSS feed -contains 15. - -Solution:
- -
-$num_items = 10;
-$rss = fetch_rss($url);
-
-$items = array_slice($rss->items, 0, $num_items);
-
-foreach ( $items as $item ) {
-
-Discussion:
- -Rather then trying to limit the number of items Magpie parses, a much simpler, -and more flexible approach is to take a "slice" of the array of items. And -array_slice() is smart enough to do the right thing if the feed has less items -then $num_items. - -See:
http://www.php.net/array_slice - - -2. Display a Custom Error Message if Something Goes Wrong
- -Problem:
- -You don't want Magpie's error messages showing up if something goes wrong. - -Solution:
-
-# Magpie throws USER_WARNINGS only
-# so you can cloak these, by only showing ERRORs
-error_reporting(E_ERROR);
-
-# check the return value of fetch_rss()
-
-$rss = fetch_rss($url);
-
-if ( $rss ) {
-...display rss feed...
-}
-else {
- echo "An error occured! " .
- "Consider donating more $$$ for restoration of services." .
- "<br>Error Message: " . magpie_error();
-}
-
-Discussion:
- -MagpieRSS triggers a warning in a number of circumstances. The 2 most common -circumstances are: if the specified RSS file isn't properly formed (usually -because it includes illegal HTML), or if Magpie can't download the remote RSS -file, and there is no cached version. - -If you don't want your users to see these warnings change your error_reporting -settings to only display ERRORs.-Another option is to turn off display_error, -so that WARNINGs, and NOTICEs still go to the error_log but not to the webpages. - -You can do this with: - -
-# you can also do this in your php.ini file
-ini_set('display_errors', 0);

-http://www.php.net/manual/en/ref.errorfunc.php

3. Generate a New RSS Feed
- -Problem:
- -Create an RSS feed for other people to use. - -Solution:
- -Use Useful Inc's RSSWriter. - -Discussion:
- -An example of turning a Magpie parsed RSS object back into an RSS file is -forthcoming. In the meantime RSSWriter is well documented. - -4. Display Headlines More Recent then X Date
- -Problem:
- -You only want to display headlines that were published on, or after a certain -date. - - -Solution:
-
-require_once('rss_utils.inc');
-
-# get all headlines published today
-$today = getdate();
-
-# today, 12AM
-$date = mktime(0,0,0,$today['mon'], $today['mday'], $today['year']);

-rss_utils.inc, and parses RSS style dates into Unix epoch
-seconds.

-Problem:
-MagpieRSS providesfetch_rss() which takes a URL and returns a
-parsed RSS object, but what if you want to parse a file stored locally that
-doesn't have a URL?
-
-Solution
-
-require_once('rss_parse.inc');
-
-$rss_file = 'some_rss_file.rdf';
-$rss_string = read_file($rss_file);
-$rss = new MagpieRSS( $rss_string );
-
-if ( $rss and !$rss->ERROR) {
-...display rss...
-}
-else {
- echo "Error: " . $rss->ERROR;
-}
-
-# efficiently read a file into a string
-# in php >= 4.3.0 you can simply use file_get_contents()
-#
-function read_file($filename) {
- $fh = fopen($filename, 'r') or die($php_errormsg);
- $rss_string = fread($fh, filesize($filename) );
- fclose($fh);
- return $rss_string;
-}
-
-
-Discussion
-Here we are using MagpieRSS's RSS parser directly without the convience wrapper -offetch_rss(). We read the contents of the RSS file into a
-string, and pass it to the parser constructor. Notice also that error handling
-is subtly different.

-
-
-
Why?
- I wrote MagpieRSS out of a frustration with the limitations of existing - solutions. In particular many of the existing PHP solutions seemed to: --
-
- use a parser based on regular expressions, making for an inherently - fragile solution -
- only support early versions of RSS -
- discard all the interesting information besides item title, description, - and link. -
- not build proper separation between parsing the RSS and displaying it. -
Features
- --
-
-
-
Easy to Use
- As simple as: --require('rss_fetch.inc'); -$rss = fetch_rss($url); -- -
- -
-
Parses RSS 0.9 - RSS 1.0
- - Parses most RSS formats, including support for - 1.0 modules and limited - namespace support. RSS is packed into convenient data structures; easy to - use in PHP, and appropriate for passing to a templating system, like - Smarty. -
- -
-
Integrated Object Cache
- - Caching the parsed RSS means that the 2nd request is fast, and that -including the rss_fetch call in your PHP page won't destroy your performance, -and force you to reply on an external cron job. And it happens transparently. - -
- -
-
HTTP Conditional GETs
- - Save bandwidth and speed up download times with intelligent use of - Last-Modified and ETag.
See HTTP Conditional Get for RSS Hackers -
-
- Configurable
- - Makes extensive use of constants to allow overriding default behaviour, and - installation on shared hosts. -
- Modular
--
-
- rss_fetch.inc - wraps a simple interface (
fetch_rss()) - around the library. - - rss_parse.inc - provides the RSS parser, and the RSS object -
- rss_cache.inc - a simple (no GC) object cache, optimized for RSS objects -
- rss_utils.inc - utility functions for working with RSS. currently
- provides
parse_w3cdtf(), for parsing W3CDTF into epoch seconds. -
- rss_fetch.inc - wraps a simple interface (
Magpie's approach to parsing RSS
- - Magpie takes a naive, and inclusive approach. Absolutely - non-validating, as long as the RSS feed is well formed, Magpie will - cheerfully parse new, and never before seen tags in your RSS feeds. - -- This makes it very simple support the varied versions of RSS simply, but - forces the consumer of a RSS feed to be cognizant of how it is - structured.(at least if you want to do something fancy) -
-
- Magpie parses a RSS feed into a simple object, with 4 fields:
- channel, items, image, and
- textinput.
-
-
channel
-$rss->channel contains key-value pairs of all tags, without
- nested tags, found between the root tag (<rdf:RDF>, or <rss>)
- and the end of the document.
-
- -
items
-$rss->items is an array of associative arrays, each one
- describing a single item. An example that looks like:
- -<item rdf:about="http://protest.net/NorthEast/calendrome.cgi?span=event&ID=210257"> -<title>Weekly Peace Vigil</title> -<link>http://protest.net/NorthEast/calendrome.cgi?span=event&ID=210257</link> -<description>Wear a white ribbon</description> -<dc:subject>Peace</dc:subject> -<ev:startdate>2002-06-01T11:00:00</ev:startdate> -<ev:location>Northampton, MA</ev:location> -<ev:enddate>2002-06-01T12:00:00</ev:enddate> -<ev:type>Protest</ev:type> -</item> -
- Is parsed, and pushed on the $rss->items array as:
-
-array( - title => 'Weekly Peace Vigil', - link => 'http://protest.net/NorthEast/calendrome.cgi?span=event&ID=210257', - description => 'Wear a white ribbon', - dc => array ( - subject => 'Peace' - ), - ev => array ( - startdate => '2002-06-01T11:00:00', - enddate => '2002-06-01T12:00:00', - type => 'Protest', - location => 'Northampton, MA' - ) -); -- -
-
image and textinput
-$rss->image and $rss-textinput are associative arrays
-including name-value pairs for anything found between the respective parent
-tags.
-
-Usage Examples:
- -A very simple example would be: -
-require_once 'rss_fetch.inc';
-
-$url = 'http://magpie.sf.net/samples/imc.1-0.rdf';
-$rss = fetch_rss($url);
-
-echo "Site: ", $rss->channel['title'], "<br>\n";
-foreach ($rss->items as $item ) {
- $title = $item[title];
- $url = $item[link];
- echo "<a href=$url>$title</a></li><br>\n";
-}
