Changing servers, and getting SyntaxError: JSON.parse: unexpected character parsererror

Question

I'm moving php code from one linux server to another, and the new one is producing rubbish.

In Firebug, the first result looks great, like normal json encoded values, and works.

The second result (new server) is preceded by "html" and "body" tags, a "p" tag, and then "quot;" instead of actual quotes around the data (sorry, I couldn't get the form to display all that), and throws an error.

In both cases, the code is the same, the output an array passed through json_encode.

Could this be a configuration error?

Thanks in advance.

Answer 1

Well, ultimately I added header('Content-type: application/json'); which removed the encoded html. I'd sure like to know why I had to do that.
