adding a new node in XML file via PHP

The best and safe way is to load your XML document into a PHP DOMDocument object, and then go to your desired node, add a child, and finally save the new version of the XML into a file.

Take a look at the documentation : DOMDocument

Example of code:

// open and load a XML file
$dom = new DomDocument();
$dom->load('your_file.xml');

// Apply some modification
$specificNode = $dom->getElementsByTagName('node_to_catch');
$newSubTopic = $xmldoc->createElement('subtopic');
$newSubTopicText = $xmldoc->createTextNode('geography');
$newSubTopic->appendChild($newSubTopicText);
$specificNode->appendChild($newSubTopic);

// Save the new version of the file
$dom->save('your_file_v2.xml');
