Bug #16048: fgets/feof failure when stdin is reading from a pipe

Operating system: Solaris 2.7  2.8
PHP version:  4.1.2
PHP Bug Type: Filesystem function related
Bug description:  fgets/feof failure when stdin is reading from a pipe

The fgets() function works differently when the input is a pipe. 
Specifically, feof() returns true after the first line is read.  The test
script and sample output follow.  The test script works fine if stdin is
redirected from a file.  It fails if stdin is a pipe.

Nothing special about the build:

./configure  --prefix=/usr/local --with-mysql

pjm@poseidon cat test.php 
#!/usr/local/bin/php -q
?php

$fd = fopen(php://stdin, r);
while (! feof($fd))
{
$buffer = fgets($fd, 4096);
echo $buffer;
}

?
pjm@poseidon  test.php ./test.php 
#!/usr/local/bin/php -q
?php

$fd = fopen(php://stdin, r);
while (! feof($fd))
{
$buffer = fgets($fd, 4096);
echo $buffer;
}

?
pjm@poseidon cat test.php | ./test.php 
#!/usr/local/bin/php -q
