PHP Encoding JSON Issue

Question

I wanna json encode a PHP array to send it for a server, but the server wants it in this format :

[{ "key1": "value1", "key2": "value2", "key3": "value3" }]

But now my associative array after using json_encode() on it looks like this:

{ "key1": "value1", "key2": "value2", "key3": "value3"}

Answer 1

The first version with the [] is an array of objects, you just have a single object. Just create an array with that single object...

echo json_encode( [ $data ] );

gives...

[{"key1":"value1","key2":"value2","key3":"value3"}]

Answer 2

You can get first element of parsed json. like this:

$json = '[{ "key1": "value1", "key2": "value2", "key3": "value3" }]';

$parse = json_decode($json,true);

echo json_encode($parse[0]);
