What potential issues or pitfalls can arise when parsing RSS feed links in PHP?

One potential issue when parsing RSS feed links in PHP is that the links may contain special characters or spaces that need to be properly encoded before being used in a URL. To solve this issue, you can use the PHP function urlencode() to encode the link before making any HTTP requests. 

// Example code snippet to properly encode RSS feed links before using them
$rssFeedLink = "http://example.com/rss feed.xml";
$encodedLink = urlencode($rssFeedLink);

// Now you can use $encodedLink in your HTTP requests
