LastRSS Limit to One Item

I'm using LastRSS (http://lastrss.webdot.cz/) to display RSS feeds from sites. The trouble is that some feeds contain long lists of links. I don't want to clutter a page with all of the links. Does anyone have a solution for limiting the display to just the first link, title and description?

I've been told that since lastRSS returns an associative array with RSS items, I can just select the first array index ( 0 ) ?

Here's the code I'm using:

1.      <?php
2.      // include lastRSS
3.      include "lastRSS.php";
4.      // Create lastRSS object
5.      $rss = new lastRSS;
6.      // Set cache dir and cache time limit (1200 seconds)
7.      // (don't forget to chmod cache dir to 777 to allow writing)
8.      $rss->cache_dir = './temp';
9.      $rss->cache_time = 1200;
10.      // Try to load and parse RSS file
11.      if ($rs = $rss->get('http://www.clickfire.com/viewpoints/blog/feed/')) {
12.          // Show last published articles (title, link, description)
13.          echo "<ul>\n";
14.          foreach($rs['items'] as $item) {
15.              echo "\t<li> <a title=\"$item[description]\" href=\"$item[link]\">".$item['title']."</a></li>\n";
16.              }
17.          echo "</ul>\n";
18.          }
19.      else {
20.          echo "Error: It's not possible to reach RSS file...\n";
21.      }
22.      ?>

Thanks.

It returns an Associate Array ( Items ) with each individual news item. it returns a numbered array 'items' with each story in its own sub array beyond that. To output only the furst you will need to drop the loop and just print the first cell from the array.

<?php

// include lastRSS library
include './lastRSS.php';

// create lastRSS object
$rss = new lastRSS;

// setup transparent cache
$rss->cache_dir = './cache';
$rss->cache_time = 3600;       // 1 hour

// load some RSS file
if ($rs = $rss->get('http://www.clickfire.com/viewpoints/blog/feed/')) {
       
             // Dump the first artical
            echo "<ul>\n";
            echo "\t<li> <a title=\"$rs['items'][0][description]\" href=\"$rs['items'][0][link]\">".$rs['items'][0]['title']."</a></li>\n";
            echo "</ul>\n";

}



?>

Looks good but I get this error when I try:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING

Sorry my bad :)

Try

<?php

// include lastRSS library
include './lastRSS.php';

// create lastRSS object
$rss = new lastRSS;

// setup transparent cache
$rss->cache_dir = './cache';
$rss->cache_time = 3600;      // 1 hour

// load some RSS file
if ($rs = $rss->get('http://www.clickfire.com/viewpoints/blog/feed/')) {
       
             // Dump the first artical
            echo "<ul>\n";
            echo "\t<li> <a title=\"$rs[items][0][description]\" href=\"$rs[items][0][link]\">".$rs['items'][0]['title']."</a></li>\n";
            echo "</ul>\n";

}



?>

The above prints out the anchor text of the link perfectly. However, the actual link and title attribute of the link are appending this:

Array[0][link]
0

Arrays in Strings are a pain :)

<?php

// include lastRSS library
include './lastRSS.php';

// create lastRSS object
$rss = new lastRSS;

// setup transparent cache
$rss->cache_dir = './cache';
$rss->cache_time = 3600;      // 1 hour

// load some RSS file
if ($rs = $rss->get('http://www.clickfire.com/viewpoints/blog/feed/')) {

             // Dump the first artical
            echo "<ul>\n";
            echo "\t<li> <a title=\"{$rs['items'][0]['description']}\" href=\"{$rs['items'][0]['link']}\">".$rs['items'][0]['title']."</a></li>\n";
            echo "</ul>\n";

}
