oci_fetch_object获取对象后转换为json的格式的问题

Question

我用oci_fetch_object获取对象，然后转换为json格式，结果输出来看了一下，不对：
({"totalProperty":"7","results":{"FX":["6410314 ","6410404 ","6410221 ","6410228 ","6410126 ","6410214 ","6410328 "],"FY":["2","1","2","1","1","2","1"],"0":{"FX":"6410314 ","FY":"2"},"1":{"FX":"6410404 ","FY":"1"},"2":{"FX":"6410221 ","FY":"2"},"3":{"FX":"6410228 ","FY":"1"},"4":{"FX":"6410126 ","FY":"1"},"5":{"FX":"6410214 ","FY":"2"},"6":{"FX":"6410328 ","FY":"1"}}}) 
居然输出了这种格式，正常的json格式应该是：
{"FX":"6410314 ","FY":"2"},"1":{"FX":"6410404 ","FY":"1"},"2":{"FX":"6410221 ","FY":"2"},"3":{"FX":"6410228 ","FY":"1"},"4":{"FX":"6410126 ","FY":"1"},"5":{"FX":"6410214 ","FY":"2"},"6":{"FX":"6410328 ","FY":"1"}
也就是说，他输出的结果先输出fx的值的组、然后是fy的值的组，然后才是正常的json格式，我十分的奇怪，请教各位这是什么问题，是不是查询oracel的函数使用的不对啊？

Answer 1

用oci_fetch_assoc获取关联数组呢？

Answer 2

({"totalProperty":"7","results":{"NAME":["6410314 ","6410404 ","6410221 ","6410228 ","6410126 ","6410214 ","6410328 "],"VISITS":["2","1","2","1","1","2","1"],"VIEWS":["2","1","2","1","1","2","1"],"0":{"NAME":"6410314 ","VISITS":"2","VIEWS":"2"},"1":{"NAME":"6410404 ","VISITS":"1","VIEWS":"1"},"2":{"NAME":"6410221 ","VISITS":"2","VIEWS":"2"},"3":{"NAME":"6410228 ","VISITS":"1","VIEWS":"1"},"4":{"NAME":"6410126 ","VISITS":"1","VIEWS":"1"},"5":{"NAME":"6410214 ","VISITS":"2","VIEWS":"2"},"6":{"NAME":"6410328 ","VISITS":"1","VIEWS":"1"}}})还是一样的，我怀疑是不是我的json的格式转换有问题，我的是php5，不支持json的最小的api，我找了个转换的函数，但是在mysql下又是对的，奇怪
