Extract image data when pulling in RSS feeds using PHP

Question

The script I am using to pull in the feed titles is:

<?php  

function getFeed($feed_url) {  

$content = file_get_contents($feed_url);  
$x = new SimpleXmlElement($content);  

echo "<ul>";  

foreach($x->channel->item as $entry) {  
    echo "<li><a href='$entry->link' title='$entry->title'>" . $entry->title . "</a>    </li>";
    $i++;
    if($i==5) break;        
}  
echo "</ul>";  
}  
?>

I would like to pull in the images for each title/article and place them next to the title.

The float part is easy. I'm having trouble getting the actual image in. I've tried that mark like this: <img src="$entry->image" />, but it didn't work.

How would I go about this please?

Yeah an image with float eft, but the float part is easy - I'm having trouble getting the actual image in. I've tried that mark like this: <img src="$entry->image" /> it didn't work. — RuFFCuT

As the answer to random's suggestion:

I'm using $item['description'] to represent the description string.
Then match for img tag
Output image tag

Then remove the image tag from the original $content and output that, you're left with just the description text

<?php 
    $content = $item['description'];
    preg_match('/(<img[^>]+>)/i', $content, $matches);
    echo $matches[0];
    echo str_replace($matches[0],"",$content);
?>

When displaying the feed contents, variables such as $entry->link and $entry->title work because they are valid, present and required elements in a standard RSS feed item.

To call $entry->image would require the source RSS to use and populate that optional element.

Some feeds may include that data, but most will not.

Alternatively, you can write your own function or method to scan the contents of the description element and find any suitable image to include as you need.
