PHP Headers To Serve JSON

    

  1. 
header('Cache-Control: no-cache, must-revalidate');

    2. 

  2. 
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');

    3. 

  3. 
header('Content-type: application/json');

    4.

The first two headers prevent the browser from caching the response and the third sets the correct MIME type for JSON.

Than just output your JSON data

    

  1. 
$data = array(

    2. 

  2. 
"fire" => 1,

    3. 

  3. 
"water" => 0,

    4. 

  4. 
"earth" => 1,

    5. 

  5. 
"air" => 1,

    6. 

  6.  
    7. 

  7. 
);

    8. 

  8.  
    9. 

  9. 
echo json_encode($data);

    10. 

  10. 
exit;

    11.

I am a full-stack developer. I love programming,  design and know my way around server architecture as well.  I would never feel complete, with one of these missing. I have a broad range of interests, that’s why I constantly dive into new technologies and expand my knowledge where ever required. Technologies are evolving fast and I enjoy using the latest. Apart from that, I am a peace loving guy who tries to have people around him that think the same.  I truly believe in the principle: “If you help someone, someone will help you, when you need it."
