Json header not working - php

Question

I have a web service and a web interface for a registered user. this section allows the user to get their statistics (like stack overflow)

• number of views
• number of responses
• number of posts
• number of support tickets, etc ...

Now this tool I allow the user to retrieve their data in json format, my problem is that the sent header does not work for all browsers

I have:

header('Cache-Control: no-cache, must-revalidate'); header('Expires: Mon, 26 Jul 1997 00:00:00 GMT'); header('Content-type: text/json'); 

Should I remove expiration and cache controls?

Answer 1

The common MIME for json is application/json .

Answer 2

You should use:

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