Return json text/msg from the php web service

Question

I have a php web service that takes the request from android/iphone app and uses the input to find the appropriate data from the mysql database. The result is encoded back to json. How can I return the json txt/msg to the android/iphone app. Please help?????

Answer 1

echo (json_encode ($data_to_send));

• Tomalak: You forgot to set the content type.
• Neeraj Dangol: 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.
• GordonM: @NeerajDangol That's how you do it. (plus sending the right content headers as Tomalak said). Echoing sends to the client.

Answer 2

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
