RSS is wild use by blogs, news sites and many others sites by entries syndication. I wrote a class (of course public domain) called gFeed that create a Stream Wrapper for easy manipulation such us creation, append and read. I’ve focus in try to give a easy interface. I hope you like it. Below are a few of examples.

How to read an remote RSS :

<?
include(“gFeed.php”);
$f = fopen(“rss://http://www.cesarodas.com/feed/”,“r”);
/* Rewinding && reading the first line, which is the RSS information. */

rewind($f);
fread($f,1);

print “<h1>${title}</h1>”;
print “<b>Link</b>: ${link}<br/>\r\n”;
print “<b>Description</b>: ${description}<br/>\r\n”;
print “<b>Generator</b>: ${generator}<br/>\r\n”;
print “<b>Lenguage</b>: ${language}<br/>\r\n”;
print “<b>Encoding</b>: ${encoding}<br/>\r\n”;

print “<br/>\r\n”;

print “<hr>\r\n”;

while ( fread($f, 1) ) {
/*

*    After the first read (information of blog), comes

*    the RSS entries

*/

print “<b>Title</b>: ${title}<br/>\r\n”;

print “<b>Link</b>: ${link}<br/>\r\n”;

print “<b>Author</b>: ${author}<br/>\r\n”;

print “<b>Date</b>: ${date}<br/>\r\n”;

print “<b>Description</b>: ${description}<br/>\r\n”;

print “<hr>\r\n”;

}

fclose($f);
?>

For open a local file just change the URI rss://file:// or rss://c:/ or rss://../..

How to write a RSS :

<?
include(“gFeed.php”);
/*
* Opening a local RSS for write a new one
*/
$f = fopen(“rss://newRSS.xml”,“w”);
/*
* Do never forget that in the 0 position the channel information
* is saved, but after that (from 1 to N) items are saved.
*/
$title=“gFeed RSS test”;

$link=“http://cesars.users.phpclasses.org/gfeed”;

$description=“RSS IO stream wreaper class”;

$date = date(“Y-m-d H:i:s”);
$language = “en”;
fwrite($f,1);
/* Add a new Entry */
$title = “Test Entry N 1″;
$link = “http://cesars.users.phpclasses.org/gfeed?test”;
$author = “Cesar D. Rodas”;
$date = ‘2007-07-24 14:17:00′;
$description = “Test description”;
