What are some best practices for reading and processing XML files in PHP?

When reading and processing XML files in PHP, it is important to use a reliable XML parsing library like SimpleXML or DOMDocument. These libraries provide easy-to-use functions for loading and navigating XML data. It is also recommended to validate the XML against a schema to ensure its correctness before processing it. 

// Load and parse an XML file using SimpleXML
$xml = simplexml_load_file('data.xml');

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