Cassandra CqlRow fetch DateType / Int32Type

phpcassa library里有个namespace ：

use phpcassaSchemaDataType;

当使用cql query得到cqlrow, int32 & Date type会乱码：

string 'phpcassaSchemaDataTypeInt32Type' (length=34)
string '��09' (length=4)
string 'phpcassaSchemaDataTypeInt32Type' (length=34)
string '��09' (length=4)
string 'phpcassaSchemaDataTypeDateType' (length=33)
string '��
:FA�' (length=8)
string 'phpcassaSchemaDataTypeUTF8Type' (length=33)
string '12345' (length=5)

这时，可以用DataType来unpack一下：

$rows = array(); 
            foreach ($cql_result->rows as $rowIndex => $cqlRow) { 
                $cols = array(); 
                foreach ($cqlRow->columns as $colIndex => $column) {
                    $type = DataType::get_type_for($cql_result->schema->value_types[$column->name]);
                    var_dump($type->__toString());
                    var_dump($column->value);
                    if($type->__toString() === "phpcassaSchemaDataTypeDateType"){
                        $cols[$column->name] = date("Y-m-d",$type->unpack($column->value,false));
                    }else{
                        $cols[$column->name] = $type->unpack($column->value,false);
                    }
                    
                }
                $rows[] = $cols;
            }

因为我有一个字段在cassandra里是timestamp类型，unpack出来的是time()的毫秒数，转换成date即可。
