What are the potential issues with concatenating XML in PHP scripts instead of using DOMDocument?

Concatenating XML in PHP scripts can lead to syntax errors, invalid XML structure, and difficulty in maintaining and updating the XML content. Using the DOMDocument class in PHP provides a more structured and reliable way to create and manipulate XML documents. 

// Create a new DOMDocument object
$xmlDoc = new DOMDocument();

// Create root element
$root = $xmlDoc->createElement('root');
$xmlDoc->appendChild($root);

// Create child elements
$child1 = $xmlDoc->createElement('child1', 'Value1');
$root->appendChild($child1);

$child2 = $xmlDoc->createElement('child2', 'Value2');
$root->appendChild($child2);

// Output the XML
echo $xmlDoc->saveXML();
