no buffering the output to browser

[Anon]

Im writting traceroute program in php.
http://home.cyberosity.com/webtools/traceroute.php?traceaddress=dhc.net

right now it works, but the problem is it has to wait for the traceroute program to finish to display the output.

I want to display in real time each hop of the traceroute.

I know how to do this PERL but I would like to know how to do this with PHP. I have tried both

output_buffering = On
output_buffering = Off

getting the same results.

Im stuck and pulling out what hair I have left

Thanks

Tony

the function flush() will flush the output buffer when called and will work in most cases. Some servers will buffer the output though, if that happens there's nothing you can do.

call ob_implicit_flush() at the start of your script

And that helps how?

Getting people to read the documentation before they post...

Carl,

thank you for your basic RTFM. I guess that is why this forum is here so you have some place to tell every one RTFM.

Jamie and Mike, the call ob_implicit_flush() at the start of your script works like nph in cgi.

but the problem I am having is that I am running a exec() and php is buffering the out put of the exec().

so I found popen() but it still buffers the out put.

this was how I was doing it before
exec("traceroute $traceaddress", $tracearray);

and with popen like this
$pipe = popen ("traceroute $traceaddress", "r");
while($new_output = fgets($pipe, 1024)) {
print "$new_output";
}
pclose($pipe);

any ideas on a work around?

It would be good if people read the docs before they post.

It would also be good if those who reply to posts read the post before they reply.

Or at least point to the right parts of the manual.

Have you tried the passthru() function instead of exec()?
