It's not usually necessary, otherwise it has to be re-written.

This is what happens when you return.
echo Json_encode ($array);
You changed it.
echo Str_replace (' [] ', ' {} ', Json_encode ($array));

------to solve the idea----------------------
You can use the Json_force_object parameter

 
  

$a =array ();

Var_dump (Json_encode ($a, json_force_object));


$a =array (a);

Var_dump (Json_encode ($a, json_force_object));

$a =array ("ret" =>0);

Var_dump (Json_encode ($a, json_force_object));

String (2) "{}"
String (19) "{" 0 ": 1," 1 ": 2," 2 ": 3}"
String (9) "{" ret ": 0}"

Json_force_object (integer)
Causes a non-associative array to output a class (Object) instead of an array. This is especially useful when the array is empty and the recipient needs a Class (Object). Effective from PHP 5.3.0.
