New Comment:
Thank you for bug report.
The garbage data you see in the browser is the correct page, but
compressed. The data is probably automatically compressed by Apache or
PHP, without setting the correct headers. Because the headers are not
set, the browser does not uncompress the page.
Please check your server settings and confirm this is the problem.
There may still be a bug here, in that flush() breaks gzip compression.
In that case we need some more information on how the compression is
configured.

Description:
------------
Looping through the output of a process opened with popen while using
flush return "garbage" in the browser. Using telnet the intended output
can be seen in (likely corrupted) chuncked encoding. Commenting out the
flush() in below code fixes the problem.
Reproduce code:
---------------
<?
$handle = popen("whois php.net", "r");
if($handle)
{
while(!feof($handle))
{
$buffer = fgets($handle);
echo $buffer . "<br />\r\n";
flush();
}
pclose($handle);
}
?>
Expected result:
----------------
the output of the command whois php.net
Actual result:
--------------
seemingly random garbage in browser. Above script available through:
