incidently, i've used telnet to port 80 to
monitor the output of the .php script that feeds
the applet, and it's clear that the problem is
on the php end. having said that, i have no
idea if this is normal 4.0.2 behavior or if it
will not be reproduced on other systems.
results of these tests are below...

# First using the php://stdout technique,
# exactly as suggested by rasmus

in order to demonstrate the problem that i'm
experiencing, i've made a small tarball with
rasmus's suggestion, and the java applet (simplified)
code that accepts the file-based gzip data, but
doesn't work with the technique rasmus suggests.
since i'm using 4.0.2, i could only try one of his
suggestions (there was no gzencode in 4.0.2).

PS successful execution of the applet simply dumps
"Hello World" into the monitor/console.

What exactly is the issue here? Why are you trying to open up stdout? You can write
gzip data directly without doing that. For example:
<?
Header("Content-type: application/x-gzip");
echo gzencode("Hello World");
?>
This works just fine. The headers are uncompressed, the content is compressed. I
don't see a bug here. stdout only makes sense when running from the command line.
Which also works just fine, by the way:
<?
Header("Content-type: application/x-gzip");
$fp = gzopen("php://stdout", "w");
gzputs ($fp, "Hello World");
?>
which when run from the command line produces:
X-Powered-By: PHP/4.0.7-dev
Content-type: application/x-gzip

Again, uncompressed headers, compressed data.

You may want to wait on closing that bug...

With respect to Sterling's suggestion that I
use header(), that was of course the _first_ thing
that I tried, but it did not work with (my PHP/4.0.2
running on Linux). I'm not sure what point he is
trying to make about perl not being php. I'm not
a perl fanatic trying to demonstrate the limitations
of php, I simply can't do what I want to do with php.
if you read the original bug report carefully, you
will see that the problem resides in not being able to
emit uncompressed headers before the compressed output,
at least when using php://stdout. i have no problem when
i use the readfile() technique: the headers are uncompressed
and the content of the file can be g-zip.

use the header() function, btw, Perl is not php,
gzopen("php://stdout", "w") is not the same as the Perl example.
