PHP Output Buffering with included files

I have one file will include other files depending on some conditions, One of these files needs to use output buffering so that the response can be returned to the browser and then some slow actions performed after.

If I run the file that I want to use output buffering directly it works correctly, but If I include this file in another it doesn't work.

For example:

the file that includes: (doesn't work)

if($action == 'blah'){
    require_once 'blah.php';       
}

blah.php: (works if called directly)

ob_start();
$buffer = ob_get_contents();
ob_clean();

header('Location: http://www.google.com');

ignore_user_abort(true);
ob_end_flush();

flush();

//Do slow stuff

How can I get this to work?

How does it fail? Is there are an error message or something? – Janis Elsts Aug 17 '12 at 17:41
I tried it on built-in PHP server (PHP 5.4.4) and it works well... – Ondřej Doněk Aug 17 '12 at 17:43
You can enable all error+warning messages via the [error_reporting()](http://php.net/manual/en/function.error-reporting.php) function, or publish the content of that parent .php file, if it is possible. – Stano Aug 17 '12 at 17:50

Ahh I think I have sorted it, I was sending some headers in the first file, thank! – Chris Aug 17 '12 at 17:52
So it's good news and this question can be discarded :) – Stano Aug 17 '12 at 17:53
Although now I am getting an issue when trying to set content type header inside the ob_clean and ob_end_flush() – Chris Aug 17 '12 at 18:10
