In what scenarios would using XML for data transmission in PHP applications be considered appropriate or overkill?

Using XML for data transmission in PHP applications may be appropriate when you need a structured format for exchanging data between different systems or platforms. XML can provide a standardized way to represent data that is easily readable and parseable by both humans and machines. However, using XML for simple data exchanges within the same system or when performance is a concern may be considered overkill. 

// Example of using XML for data transmission in PHP

// Create an XML document
$xml = new DOMDocument();
$xml->formatOutput = true;

// Create root element
$root = $xml->createElement("data");
$xml->appendChild($root);

// Add data elements
$data1 = $xml->createElement("item", "value1");
$root->appendChild($data1);

$data2 = $xml->createElement("item", "value2");
$root->appendChild($data2);

// Output XML
echo $xml->saveXML();
