What are the best practices for handling invalid XML data in PHP scripts?

When handling invalid XML data in PHP scripts, it is important to use error handling techniques such as try-catch blocks to catch any parsing errors. Additionally, using XML validation tools like libxml functions can help identify and handle invalid XML data more effectively. It is also recommended to sanitize and validate input data before attempting to parse it as XML to prevent potential security vulnerabilities. 

try {
    $xml = new SimpleXMLElement($invalidXmlData);
    // Handle valid XML data here
} catch (Exception $e) {
    // Handle invalid XML data error
    echo "Invalid XML data: " . $e->getMessage();
}
