ARC2 comes with a built-in RDF format detector for convenient parsing. You can instantiate the generic RDF parser and let ARC detect RDF/XML, Turtle, N-Triples, RSS 2.0, SPOG (constrained SPARQL XML results), Google's Social Graph API JSON, or HTML (more formats such as Atom are in the works):
You can also access a specific parser directly:
or
This method will by default flatten the object values. To keep object type / datatype / language information, you can use

$parser = ARC2::getRDFParser();
You can also access a specific parser directly:
$parser = ARC2::getRDFXMLParser();
$parser = ARC2::getTurtleParser();
Parsing a remote document
$parser->parse('http://example.com/foaf.rdf');
Parsing a local document
$parser->parse('data/foaf.ttl');
Parsing data
$parser->parse($base, $data);
Retrieving a flat triples array after parsing
$triples = $parser->getTriples();
Retrieving triples indexed by subject -> predicates -> objects
$index = $parser->getSimpleIndex();
$index = $parser->getSimpleIndex(0);
