What potential issues can arise when creating or editing XML files using PHP, especially when dealing with file caching?

When creating or editing XML files using PHP, potential issues can arise with file caching if the cached data does not reflect the most recent changes made to the XML file. To solve this issue, you can disable file caching or ensure that the cache is updated whenever the XML file is modified. 

// Disable file caching
libxml_use_internal_errors(true);

// Load XML file
$xml = simplexml_load_file('example.xml');

// Make changes to XML file

// Save changes to XML file
$xml->asXML('example.xml');

// Clear cache
libxml_clear_errors();
