New Comment:
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.

With perl cgi I can create a GZIP output stream
to a Java applet as follows:
print("Content-type: application/x-gzip\n\n");
my $gz=gzopen(\*STDOUT, "wb") || die("gasp!");
however, the same technique seems to be impossible
with php://stdout. i realize that i can open
a gzip'd stream as follows (note: i am using php 4.02):
gzopen("php://stdout","w");
however, there seems to be no way to get header fields
(uncompressed) to precede the gzip'd output. this
presents an unresolvable problem on the browser side,
because some browsers will assume that no data has been
sent if no header fields are received.
can the php://stdout mechanism be changed to allow me
to print uncompressed lines to stdout before the compressed
output begins? am i missing something here? i realize
that i can put zipped data into a file and use readfile()
to send it, and this actually does send all the header
fields as would be expected. however, this will cause
me unnecessary drive activity because i will have to modify
the files, which i had not wanted to do.
