PHP header redirect working in nginx even output sent

  • 772

note: There is a similar question but that's about Apache.

The following code

<?php
echo '.';
header('Location: http://stackoverflow.com');

is fully 'working' under nginx 0.7.67 where 'working' means the php redirect is working fine without errors in the error log or displaying the ..

How can i force nginx or php-fpm to throw the PHP Warning: Cannot modify header information - headers already sent by warning?

    You should check value of output_buffering parameter in your php.ini file.

    php.ini #output-buffering

  2. I had the same problem and I found that it was because a header("Status: 200 OK", false, 200); before the header to redirect. So I added a condition not to display the header 200 if I know that I will have to redirect:

    if(!isset($_GET['utm_source'])) { //Header will be Redirect 301 from global_cookies.inc.php
    header("Status: 200 OK", false, 200);
}

    Note: With Apache I had not this problem and could redirect even after a header 200.
