[SOLVED] rss and php

[ohdang888]

i'm grabbing the rss feeds from this site: http://www.markwarner2008.com/feed/blog/index.xml

 

view the page source of that file... its weird... some stories have the xml tag of "summary" but others don't, yet they all have a text summarry.

 

here's what i'm getting:

so how would i display all the stories, though some don't have a "summary" tag

 

 

php code is below......

 

<?php
require_once 'rss_fetch.inc';
$url = 'http://www.markwarner2008.com/feed/blog/index.xml';
$rss = fetch_rss($url);

$max = 80;
$x = 0;
foreach ($rss->items as $item ) {

if($max <= $x){
//do nothing
}else{
$title = $item['title'];
$url = $item['link'];
$summary = $item['summary'];
$content = $item['content'];

print_r($a);

$author = $item['name'];

$summary = substr($summary, 400);
$summary = $summary."...";





echo "<a href='$url'>$title</a><br>Summary:$summary.<br>$content<br>";
}
//$x++;
}

echo "Done!";
?>

All the stories will display but if they dont have a summary then it simply wont display a summary.

Im confused at this post.

If there's no summary, display content tag (truncate if needed)

 

if (!empty($summary)) {
$summary= substr($summary, 400);
$summary = $summary."...";
} else {
$summary= substr($content, 400);
$summary = $summary."...";
}
