New Comment:
Without having had time to dig deeper just yet, if you open for write
only, you shouldn't expect to be able to read. This application-level
error is reflected as EOF.
So the question becomes, is this behavior different from libc, and did
the php behavior change between releases? (I'm not including PHP 6 in
that, because it is not released yet)
If the latter, we need to fix it, it not, we probably shouldn't fix it
if there's a risk of breaking an app.
I'm leaning towards won't fix; you should open the file as you intend
to use it.

Description:
------------
fgetc() sets the end of the file flag to ture when reading from a file
which opened in write only mode.
This failure is applicable on php5 and php6
php version:
PHP 6.0.0-dev (cli) (built: Jul 18 2007 20:53:03) (GCOV)
Copyright (c) 1997-2007 The PHP Group

Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
OS : RHEL 5
configure setup:
./configure --enable-gcov
Reproduce code:
---------------
<?php
$fp = fopen("test.txt", "w");
var_dump( fwrite($fp, "Text") );
// rewind the file pointer to begining
var_dump( rewind($fp) );
var_dump( ftell($fp) );
var_dump( feof($fp) );
// try to read
var_dump( fgetc($fp) );
var_dump( ftell($fp) );
var_dump( feof($fp) );
fclose($fp);
unlink("test.txt");
?>
Expected result:
----------------
output - php5:
--------------
int(4)
bool(true)
int(0)
bool(false)
bool(false)
int(0)
bool(false)
output - php6:
--------------
int(4)
bool(true)
int(0)
bool(false)
bool(false)
int(0)
bool(false)
Actual result:
--------------
output - php5:
--------------
int(4)
bool(true)
int(0)
bool(false)
bool(false)
int(0)
bool(true)
output - php6:
--------------
int(4)
bool(true)
int(0)
bool(false)
string(1) ""
int(0)
bool(true)
output on php6 when run using run-test.php :
int(4)
bool(true)
int(0)
bool(false)
string(1) "ΓΏ"
int(0)
bool(true)
