what is the header to stop buffering?

[laredotornado@zipmail.com]

Hi,

I'm using PHP 4.4.4. What is the header I need to send in order for
output to be continuously sent to the client browser as opposed to it
being buffered and all sent at once?

Thanks, - Dave

Disable output buffering in php.ini

output_bufferin g = Off

but it will not work!

PHP will spew out characters as fast as it has them, then Apache (or
whatever your webserver is) will get hold of them and buffer them :)
So you need to stop Apache (or ...) from buffering (I don't know how to
do that ... you might want to ask in an appropriate newsgroup). If you
manage that, then you'll have proxies, firewalls, routers, ..., between
the webserver and the client browser. They all /may/ add buffering on
their own. Even if they don't, the client browser /may/ buffer the
incoming data before displaying it.

So ... don't worry about it!

Dave,

There aren't any headers you can send. However, you can cause the data
to be sent to the browser immediately with:

ob_flush();
flush();

This will cause PHP to flush the output immediately, and generally
Apache will do the same. Whether or not it will be displayed
immediately, however, is up to the browser.

I had a similar problem that the flush commands did not resolve.

Called my hosting ISP - techie there found that something called "mod_gzip"
was 'on' - turned it 'off' and problem solved.

Hope it helps

Dave

And a little trick for browser is to send 1024 or more spaces anywhere where
it is possible in html content.
Example:

<p>some text which should be unbuffered</p>
......1024 spaces here...
<?php ob_flush(); flush(); ?>
<p>another text</p>

That depends on the buffer size. 1024 may be large enough - or it may not.

Plus it raises your bandwidth 1K every time you do it - not to mention
the extra download time the client requires, especially if it's a
dial-up connection.

Not a real good idea, actually.
