PHP convert Array to JSON issue?

Question

When I print_r($arr) something like Array ( [0] => Hello [1] => world); is output.

I tried to convert in JSON string using below code.

$result['result'] = $arr;
json_encode($result);

This results in this JSON string:

{"result" : { "0" : "hello" , "1" : "world"}}

The expected result would be this:

{ "result" : ["hello" , "world"]}

What can I do to get the desired output?

Is that really your code? Where does the array come from? The second result looks like the one you would get. — Florian, Apr 24 '15 at 06:35

`print_r($arr)` Output looks like `Array ( [0] => Hello [1] => world);` — Gunjan Patel, Apr 24 '15 at 06:37
Yes, with $arr = array("Hello", "world"); you would get your wanted result, so show your $arr ;) — Florian, Apr 24 '15 at 06:37
Simply you can't basically json also returns an array so to access an array you have to use it's indexes as well. — Sunil Pachlangia, Apr 24 '15 at 06:38

Array ( [0] => Hello [1] => world); -> if that's really the output he got, than $arr isn't an object, it's an array ;) – Florian Apr 24 '15 at 06:51
ok its my mistake :) – user3284566 Apr 24 '15 at 06:51

put your array values to the result key of array. then it will print the required result.

$arr = array("0"=>'one',"1"=>'two');
$result['result'] = array_values($arr);
echo json_encode($result);
