转换数据以制作Google Chart

Question

我在汇总表中有这些数据：

REGIS_ID    VAC_NAME    LOC_DETAIL
1   Flu University
2   Flu University
3   Flu University
4   Flu Office
5   Flu School
6   Flu Office
7   Flu School
8   Flu School
9   Flu School
10  Flu School
11  Flu University
12  Flu University
13  Hepatitis-B School
14  Hepatitis-B School
15  Hepatitis-B School
16  Hepatitis-B Office
17  Hepatitis-B Office
18  Bird_Flu    University
19  Bird_Flu    University
20  Bird_Flu    School
21  Bird_Flu    School
22  Bird_Flu    School
23  Bird_Flu    Office
24  Bird_Flu    Office
25  Bird_Flu    University

所以我想查询并将数据转换为PHP，如下所示：

$dataTest = "['', 'Bird_Flu', 'Flu', 'Hepatitis-B'],
['School', 3, 5, 2],
['University', 3, 5, 3],
['Office', 2, 2, 2]";

制作Google Chart：

我该怎么办？非常感谢你。

Answer 1

我过去做了类似的事情，我只是用代码来构建所需格式的字符串

//sudo code
$dataTest = ""
foreach(datarow)
{
    $dataTest += "['School', 3, 5, 2],"
}
