急求php+hbase接口中的条件过滤详细解说

Question

php+hbase中的

$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 );


使用方法，求大神指教，说明地方错了呢？？
主要不明白
$filter="SingleColumnValueFilter ('track:month', 'track:month', >=,'binary:2')";
里面的条件组合问题
