What are some common methods for changing the content of an RDF file using PHP?

One common method for changing the content of an RDF file using PHP is to parse the RDF file, make the necessary changes to the data, and then serialize the modified data back into RDF format. This can be done using libraries such as EasyRdf or ARC2 in PHP. 

require_once 'vendor/autoload.php'; // Include the necessary library

// Load the RDF file
$graph = new EasyRdf_Graph();
$graph->parseFile('data.rdf');

// Make changes to the RDF data
$resource = $graph->resource('http://example.org/resource1');
$resource->set('dc:title', 'New Title');

// Serialize the modified data back into RDF format
$updatedData = $graph->serialise('rdfxml');
file_put_contents('updated_data.rdf', $updatedData);
