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?
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.
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.
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
