Error in JSON response from PHP

[satishs]

I am trying to return a simple JSON response from PHP on server. The JSON response seems to be formatted correct - I've validated it, but for some reason I am getting

Uncaught SyntaxError: Unexpected token :

error and my store fails to load.

I've tried setting content type to application/json as mentioned in many forums.

<?php header('content-type: application/json; charset=utf-8');

response seems to be interepreted as MIME type text/html - not sure if this is the problem, but couldn't get that changed.

Here is the JSON response:

{"sb3model":[{"sbfor":"Ayy","sbname":"Har","sbloc":"a"},{"sbfor":"Muruga","sbname":"Ska Sas","sbloc":"b"},{"sbfor":"Gan","sbname":"Maa Gap","sbloc":"c"}]}

Any help will be great!.

Thanks,
ST

hi guys, I was able to get the Response Content-Type to be in applicaiton/json MIME type. But still running into this error- JSON is valid- this is driving me nuts,

Uncaught SyntaxError: Unexpected token :

folks..it finally worked. being a newbie, every step seems to be a challenge, - but thanks to helpful posts on the web.

here is what I had to do...

After getting the MIME type straight.

I changed the code to implement callback as it is JSONP

echo json_encode(array('sb3m'=>$arr)) // this may be valid for a JSON response.

to

echo $_GET['callback'].'('.json_encode(array('sb3m'=>$arr)).')'; // key here $_GET... as this handles JSONP requests from a different server than responding server.
