How can simplexml be used to parse and manipulate XML data in PHP?

Simplexml in PHP can be used to easily parse and manipulate XML data. To parse an XML file, you can use the simplexml_load_file() function to load the XML file into a SimpleXMLElement object. Once the XML data is loaded, you can access and manipulate it using object-oriented methods provided by SimpleXMLElement.

// Load XML file
$xml = simplexml_load_file('data.xml');

// Access and manipulate XML data
foreach ($xml->children() as $child) {
    echo $child->getName() . ": " . $child . "<br>";
}
