How can XML files be effectively read and parsed using PHP?

To effectively read and parse XML files using PHP, you can use the SimpleXML extension which provides a simple and easy way to work with XML data. This extension allows you to load XML files, access elements and attributes, and manipulate the XML structure in a straightforward manner.

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

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