Hi,
I've got a PHP script (running on MacOS X, PHP 4.1.12) which uploads
bookings from one database to another, and I'd like to have the screen show
progress as it happens (each time I process a booking, I write a line
summarising it to the browser with 'print')
From RTFMing and Googling, it seems that I should be able to do this by
turning output buffering on and using ob_flush() et al. However, this only
sort-of works, in that instead of getting output line by line, I get a
multi-line chunk on the browser from time to time.
Am I stuck with having this chunk-by-chunk visualisation, or can anyone
please suggest a way that I can make it force each line to the browser as I
write it?
Thanks in anticipation,
David C 2 2310
Here is an example which works for me, but I personaly recommend not to
use buffering at all
<?
function sample($buffer) {
global $i;
if(!isset($i)) $i = 1;
$bufer = "$i<br />";
$i++;
return ($bufer);
}
// don't forget to start buffering
ob_start("sampl e");
ob_flush();
ob_flush();
ob_flush();
ob_flush();
// and don't forget to end it
ob_end_flush();
?>

the result you see may depend on your browser, web server etc...
I did something similar in perl and got character by character output in
mozilla but not in IE.

Hello,
I am testing buffering an asp page and Flushing information out to the

The loops are suppose to simulate long search processes with a flush after
each search.
When i Navigate to the page, redirect to it from another page, or type the
URL to this page in the browser, the page is buffered until it reaches the
end of the file and is then displayed all at...

Hi!
I'm working on a website with an IHttpHandler that listens to changes ina
database and sends some text to the client. The client is always connected
to the handler, this way I can use a push method.
Every time a text is to be sent I flush the buffer. The problem is, that
there seems to be a minimum size the buffer has to have before asp.net
really flushes the buffer and sends the data.
As a workaround I insert a few 100...

Hello Everybody!
I am writing a networking application in python for a small piece of
hardware, in which there could sometimes be timeouts. I am using
sockets to communicate to this device. Data that is sent to the device
is instructions for that piece of hardware, and data recieved is just
responses from that hardware.
When a timeout happens, for some reason extra data is stored inside
the buffer, so when the timeout is over, that...

I have a big asp file that has an error under certain conditions -- totally
repeatable. However, it only fails when I set response.buffer = True at the
top. WHen I set it False in order to debug it, it works every time! I even
set it to True, but did a .Flush just before the error, and the error won't
happen.
It only happens when response.buffer is True and no .response.flush is issued.
The error is a string variable turns-up empty...

this is from mentioned section. i did not understand some things here:
it means "flushing the buffer" and "writing to output device" are SAME
thing, these are just 2 different names for the same thing.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
