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

It is also good to set the access security - just replace * with the domain you want to be able to reach it.

 '1',
        'value1'=> 'value1',
        'value2'=> 'value2'
    );

echo json_encode($response); 
?>
