现在，您可以获得一个多行的结果集，其中每一行表示一个唯一值（红色、蓝色和绿色），并且得到该值在表中的出现次数计数。
Now you get a multi-row result set, each row relating to a unique value (red, blue, and green), and a corresponding count of the occurrences of that value in the table.
仅使用Jena的API查询像WordNet这样巨大的模型将有一定的限制性，因为要执行的每类查询都将需要专门编写多行的代码。
Querying a model as large and as rich as WordNet using Jena's API alone would be restrictive, as each type of query to be performed would require several lines of bespoke code to be written.
通过该模板，可将获得的所有数据（数组格式的、多行的、单值的或JSON 数据结构中的任何内容）转换成原生PHP 格式，放在 $value变量中。
With that, you've got all the data -- array format, multiple rows, single values, whatever you stuffed into your JSON data structure -- into a native PHP format, in the $value variable.
