因为
"StartDate":new Date(1350691200000),
造成的,把它从字符串中都拿掉就可以了.你试试,我刚才调试过试验了.
你也是用 $data = json_decode($output);print($data);这样吗？  这个也试了，打印无数据、头部是不是要加包含什么json类或者对象文件？
$s='{"total":359,"data":[{"Id":113023,"ProductId":2905,"ProductCode":"SZX01","ProductName":"计算机图书系列","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":"儿童图书教系列","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}]}';
$s=preg_replace('/new Date[^,]+/','"$0"',$s);
print_r(json_decode($s));

我也测试理下，是new Date(1350691200000)这里有问题。
加上双引号就可以了。$str = '{"total":359,"data":[{"Id":113023,"ProductId":2905,"ProductCode":"SZX01","ProductName":"计算机图书系列","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":"儿童图书教系列","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}]}';
后来我让网站A方修改了startDate的字段格式，用json_decode就解析成功了、、问题解决了，很开心，谢谢大家的建议、
