将结果提取到JSON数组PDO

Question

im using fetchAll(PDO::FETCH_ASSOC) of the PDO class for fetching my results, then i take the result and run it through json_encode($results) which results in :

{ "0" : { "key" : "value" }, "1" : { "key" : "value" } }

But i was expecting :

 [ { "key" : "value" },{ "key" : "value" } ]

as Json array is more natural and reasonable then Json object in my case.

How would you go about either converting the json object to json array, or get the json array in the first place by using some other fetch style or any other suggestion?

Answer 1

Ok it heppened because i had some other type values in that json, something like :

{ "0" : { "key" : "value" }, "1" : { "key" : "value" } , "key" : [ { "key" : "value" } ]}

I just introduced a key for the array and it worked :

{ "key" : [{ "key" : "value" },{ "key" : "value" }] , "key" : [ { "key" : "value" } ]}
