php+hbase使用问题，请教大神

Question

我最近用php+hbase开发一个项目。在用scan传参数的时候。
filter="SingleColumnValueFilter ('track:month', 'track:month', >=,'binary:2')";
$tableName = "ais_home:original";

$scan = new Hbase\TScan();
$scan->columns=array('track:month','base:mmsi');
$scan->filterString=$filter;

$scanner = $client->scannerOpenWithScan( $tableName , $scan, null);

$get_arr = $client->scannerGetList($scanner,$nbRows );

请问filter="SingleColumnValueFilter ('track:month', 'track:month', >=,'binary:2')";应该怎么用啊
