What debugging techniques can be used to identify the source of the issue in the PHP RSS parser?

Issue: The PHP RSS parser is not displaying the expected results, which could be due to errors in the code or the RSS feed itself. To identify the source of the issue, debugging techniques such as using var_dump() to inspect variables, checking for syntax errors, and validating the RSS feed structure can be helpful. 

<?php

// Debugging the PHP RSS parser
$url = 'https://example.com/rss-feed'; // Replace with the actual RSS feed URL

$xml = simplexml_load_file($url);

if ($xml === false) {
    die('Error loading XML');
}

// Debugging - inspect the XML object
var_dump($xml);

// Parse and display the RSS feed
foreach ($xml->channel->item as $item) {
    echo $item->title . '<br>';
    echo $item->link . '<br>';
    echo $item->description . '<br>';
    echo '<br>';
}

?>
