**isomorphic**(Graph $graphA, Graph $graphB)

Check if one graph is isomorphic (equal) to another graph

For example: $graphA = EasyRdf\Graph::newAndLoad('http://example.com/a.ttl'); $graphB = EasyRdf\Graph::newAndLoad('http://example.com/b.ttl'); if (EasyRdf\Isomorphic::isomorphic($graphA, $graphB)) print "Equal!";
