Returning JSON from a PHP Script?

Question

I want to return JSON from a PHP script. Do I just echo the result? Do I have to set the `Content-Type` header?

Answer 1

You can use json_encode to return JSON format of your result.

For example

$arr = array("name" => array("John", "Doe"));

echo json_encode($arr);

this will return json format {"name":["John","Doe"]}
