嗨，我正在使用它zend project来生成图表，google charts api它使用数据库中的值来查看表格，从“1 月到 12 月”的年份和月份，它们的值低于它们。下面是我的脚本。一切正常，但是当我单击链接输出图表时：我得到了我的代码......以数组的形式而不是可视图表的形式。
['Year', 'Month', ''Value'], ['2008","january,'65], ['2008","february,'56], ['2008","march,'78], ['2008","april,'3], ['2008","may,'67], ['2008","june,'34], ['2008","july,'74], ['2008","august,'85], ['2008","september,'97], ['2008","october,'57], ['2008","november,'58], ['2008","december,'34]
我究竟做错了什么？请帮忙
