What are common errors and solutions when using PHP to parse and display news entries in an RSS feed based on specific categories?

Issue: One common error when parsing and displaying news entries in an RSS feed based on specific categories is not properly filtering the entries based on the desired category. To solve this, you can use SimpleXMLElement to parse the RSS feed and filter the entries based on the category tag. 

// Parse the RSS feed
$rss = simplexml_load_file('https://example.com/rss-feed');

// Define the desired category
$category = 'technology';

// Display news entries based on the specified category
foreach ($rss->channel->item as $item) {
    $categories = $item->category;
    if (in_array($category, $categories)) {
        echo '<h2>' . $item->title . '</h2>';
        echo '<p>' . $item->description . '</p>';
        echo '<a href="' . $item->link . '">Read more</a>';
    }
}
