You forgot to set the content type.

this code will only convert the database result(in array) to json. I want to return the json txt to the corresponding mobile. The mobile app is used simultaneously by many users.

@NeerajDangol That's how you do it. (plus sending the right content headers as Tomalak said). Echoing sends to the client.

short answer : Use json_encode();

echo json_encode($data);

long answer :

Don't forget headers :

header('Content-type: application/json');

Beware of errors, don't echo them, or echo them in json with json_encode() So, you need to configure PHP (or at least this page) :

not to show errors and to log them
handle errors as array or directly in json
