Description:
------------
When feof is called on an empty tcp stream opened by fsockopen, php will hang indefinitely.

In adition to 5.0.0, I also tested with 5.0.x-dev (Jul 29, 2004 16:30 GMT) and 5.1.x-dev (Jul 29, 2004 14:30 GMT). Each test was run with the cli executable.

When attempting to debug this issue with Zend Studio 3.5, I found stopping execution during this hang will cause php.exe or apache.exe to crash when using local or remote debugging respectively.

Adding:
fwrite($stream, "GET / HTTP1.0\r\n\r\n");
before the call to feof will result in proper execution of the script.

Reproduce code:
---------------
<?
set_time_limit(15);
$stream = fsockopen('www.google.com', 80, $errno, $errstr, 5);
stream_set_timeout($stream, 5);
echo feof($stream) ? 'true':'false';
fclose($stream);
?>

Expected result:
----------------
false

Actual result:
--------------
hang

Okay, I tried the latest builds.

Thanks Wez.
