Re: [PHP3] gzipping to stdout? From: Adam Coyne (adam <email protected>)
Date: 03/25/99

Sorry, I should clarify that-- I have a windows app which pulls gzipped data
from the web server by loading a php page, so I do want compressed output to
be sent to the browser. The way I'm doing it now accomplishes what I want,
but with a slight delay before data begins streaming out... I'm curious if
there's a way to send it straight to stdout, rather than writing it to a gz
file and then sending that.

(I figured I could write it to /dev/stdout, but got permission denied trying
to gzopen it, although I can cat stuff to /dev/stdout if I 'su nobody', whom
apache is running as... I was guessing it might be a restriction of running
php as a module or something.)
