How can XML files be validated using an XSD schema in PHP?

To validate XML files using an XSD schema in PHP, you can use the `DOMDocument` class along with the `schemaValidate` method. First, load the XML file into a `DOMDocument` object, then set the XSD schema using the `schemaValidateSource` method. Finally, call the `schemaValidate` method to validate the XML file against the XSD schema. 

$xml = new DOMDocument();
$xml->load('file.xml');

if ($xml->schemaValidateSource(file_get_contents('schema.xsd'))) {
    echo 'XML is valid.';
} else {
    echo 'XML is invalid.';
}
