PHP输入json数据的问题

Jun 20, 2016 pm 12:31 PM

我先用SQL查询出数据库里的数据,然后对其进行遍历,最后用 json_encode编码输出,结果输出的不是json类型的,请问各位大神,怎么解决,万分感激!

那就是json数据,你偏要说不是json类型的。

你输出的结果就是json类型 ,只是你这样看的话是有点问题,你去百度在线json格式化 ,把你的数据放进去格式化一下就行了,但是这个数据不影响你的查询结果,只是json显示的问题。

这个结果看起来确实是json,但是我在js里用ajax进行解析,得到结果如下:
1、我在ajax里把datatype写为json,什么结果都得不到


2、我把datatype注释掉,然后输出data,结果得到一个字符串



所以我这里就搞不懂了。


这是哪来的?也算 json 吗?

把html 里的

这个是因为你的这个页面还有HTML代码,所以你在echo $phptest; exit;增加这个exit;停止输出,记得前面不要用php输出HTML代码

感谢各位大神,问题已解决
