PHP-FPM ignore_user_abort not working

I noticed ignore_user_abort does not work with Centminmod, basically what I am trying to do is to let it continue the request even after the client exit.

I don't know why, but I've read online and tried to disable safety mode etc which isn't even enabled from what I know.. no success..

suggestions?

apparantly i need to make sure
fastcgi_ignore_client_abort off;

is set to off, no idea where and what file.. php.conf doesn't even contain it, also adding it to it won't work.

PHP:

 ob_end_clean();
 header("Connection: close");
 ignore_user_abort(); // optional
 ob_start();
 echo ('Text the user will see');
 $size = ob_get_length();
 header("Content-Length: $size");
 ob_end_flush(); // Strange behaviour, will not work
 flush();            // Unless both are called !
 session_write_close(); // Added a line suggested in the comment
 // Do processing here 
 sleep(30);
 echo('Text user will never see'); 

example script that does not work, it waits till its finished.. however it does not show the text, but it does wait 30 seconds

 

so basically it should work? i made it to off in php.ini

that means it SHOULD work

 

Tried, still waits 30 seconds..

 

no since i tried it on shared hosting and it works completely fine.

phpinfo()

ignore user abort isnt even neccesary, however not sure what else could cause it?

this is what i am using pretty much
ob_end_clean();
header("Connection: close");
ignore_user_abort(); // optional
ob_start();
echo ('Text the user will see');
$size = ob_get_length();
header("Content-Length: $size");
ob_end_flush(); // Strange behaviour, will not work
flush(); // Unless both are called !
session_write_close(); // Added a line suggested in the comment
// Do processing here
sleep(30);
echo('Text user will never see');

works totally fine on other apache servers but not this lampstack,

 

conclusion. nginx don't work with ob flush
