What are some best practices for ensuring the integrity of XML files when reading them in PHP, especially when encountering errors like "Extra content at the end of the document"?

When encountering errors like "Extra content at the end of the document" in XML files while reading them in PHP, it is essential to validate the XML structure before processing it. One way to ensure the integrity of XML files is to use PHP's built-in SimpleXMLElement class along with try-catch blocks to handle any parsing errors gracefully. 

<?php

$xmlString = file_get_contents('example.xml');

try {
    $xml = new SimpleXMLElement($xmlString);
    // Process the XML data here
} catch (Exception $e) {
    echo 'Error parsing XML: ' . $e->getMessage();
}

?>
