Spent several hours on this now, to no avail.

Simply trying to turn output buffering off on a clients WHM install, for a simple XHR response log. For testing, I have a very simple PHP script, which on the CLI does exactly what it needs to, however through a web browser, it executes the whole script before returning everything.

Environment - WHM, PHP 5.6, PHP FPM, Apache 2.4

Steps taken so far:

Ensured gzip is off (confirmed via https://checkgzipcompression.com)
In the .htaccess file added SetEnv no-gzip 1 (confirmed as it toggles the above step on/off
Set in the php.ini file output_buffering = 0 and zlib.output_compression = Off
Set in http.conf FcgidOutputBufferSize 0 and restarted apache

Any help or assistance would be gratefully received, I've done an extensive search on Stack Overflow and tried everything that I've found however with no luck.

Did you find this one https://stackoverflow.com/questions/8882383/how-to-disable-output-buffering-in-php and tried flushing? Also note that it could be a browser behaviour (let me try to find a source for that)... – Kasper Agg Dec 16 '18 at 00:04
This might help: http://php.net/manual/en/function.flush.php. By the way, what does WHM mean? – Kasper Agg Dec 16 '18 at 00:12
@KasperAgg hover your mouse over the "whm" tag in the question ;). – spinkus Dec 16 '18 at 00:24
I don't have a mouse ;-) – Kasper Agg Dec 16 '18 at 00:25
@KasperAgg tried all of those I'm afraid – Graeme Leighfield Dec 16 '18 at 00:58
Could you share some of that code? What browser did you test with? Did you test with curl? What is the whole script and what is everything? What are you expecting instead? – Kasper Agg Dec 16 '18 at 01:03
