Android Json Parsing | Php Scripts And Validate Json

I have a database in phpmyadmin panel. And I want to see this databases as json format. When I paste my link to http://jsonlint.com/. It says Null. What's wrong with my php script?

Solution 1:

You are missing a letter in the word "response" on the echo line. That's why you are getting NULL.

Replace

echo json_encode(array("server_response"=>$respose));

By this

echo json_encode(array("server_response"=>$response));

---

Also, you should set the header to application/json

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

Final code should be:

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

echo json_encode(array("server_response"=>$response));

Solution 2:

You have a typo ($respose) in the line

echo json_encode(array("server_response"=>$respose));

which should be

echo json_encode(array("server_response"=>$response));
