Disable output buffering on my local XAMPP server

Question

For some reason my XAMPP server is buffering the output of my PHP. I want it to spit it out as it goes. Anyone any ideas which settings I need to change to achieve this?

Did you force flush() in your code to see the output being sent to your screen? – Jacintajacinth

add ini_set('display_errors',1);error_reporting(E_ALL); at the top of your script – Byandby

Answer 1

XAMPP appears to set output_buffering to 4096 by default. (So content is served in 4K chunks - a possible performance benefit. Although this can lead to unexpected bugs (eg. "headers already sent" etc.) if deploying on a server where this is disabled, which incidentally is the PHP default.)

In php.ini:

; Default Value: Off
; Development Value: 4096
; Production Value: 4096
; http://php.net/output-buffering
output_buffering=4096

Set to:

output_buffering=Off

And restart your server.

Check out ob_end_flush(), the manual's chapter on output control - specifically the php.ini settings.

Of course if you're just getting a blank page, check your error reporting settings - it's very possible an error halts the script, and with error reporting off you see nothing.

I checked in the php.ini output buffering is off and ob_end_flush does not give an output... could anything else be stopping my script from echoing during execution? – Wolbrom

If you're using some kind of framework, it maybe setting up output buffering regardless of the settings. If all you get is a blank page, check error reporting. Any example code/output? – Mele

Answer 3

if you are debugging this in Xdebug and checking the output in the browser there might several reason for that. 1) php 2) apache (web server) 3) Web browser
