What are some potential pitfalls of concatenating XML data into a string in PHP?

Concatenating XML data into a string in PHP can lead to syntax errors or invalid XML structure if not handled properly. To avoid this, it is recommended to use PHP's built-in SimpleXMLElement class to create and manipulate XML data, ensuring proper formatting and avoiding errors. 

// Create a SimpleXMLElement object to handle XML data
$xml = new SimpleXMLElement('<root></root>');

// Add XML data to the object using addChild() method
$xml->addChild('element1', 'value1');
$xml->addChild('element2', 'value2');

// Output the XML data as a string
echo $xml->asXML();
