json資料解析返回為空白，哪裡出問題了？
事情是這樣的：

A網站提供一個串連介面，我驗證登入資訊通過後，返回一個json資料；但是我用$response = json_decode($output)；卻得不到資料、返回是空; 請教罈子裡高手，怎麼才能正確解析json資料成數組呢 、
資料部分截取：

PHP code

{"total":359,"data":[{"Id":113023,"ProductId":2905,"ProductCode":"SZX01","ProductName":"電腦圖書系列","ProcessDays":1,"ProcessResume":"","WorkDayPrice":79.0000,"WeekdayPrice":89.0000,"NormalPrice":0.0000,"Catalog":"0","Type":0,"RDCatalog":0,"BizCatalog":0,"StartDate":new Date(1350691200000),"Deleted":0},{"Id":113024,"TourId":2905,"ProductCode":"SZX01","ProductName":"兒童圖書教系列","ProcessDays":1,"ProcessResume":"","WorkDayPrice":79.0000,"WeekdayPrice":89.0000,"NormalPrice":0.0000,"Catalog":"0","Type":0,"RDCatalog":0,"BizCatalog":0,"StartDate":new Date(1350777600000),"Deleted":0}]｝

My Code是這樣的：

PHP code

------解決方案--------------------
因為
"StartDate":new Date(1350691200000),
造成的,把它從字串中都拿掉就可以了.你試試,我剛才調試過實驗了.
