#45759 [NEW]: feof(FALSE) should return TRUE

From:             stuff at axxess dot co dot za
Operating system: Linux
PHP version:      5.2.6
PHP Bug Type:     Filesystem function related
Bug description:  feof(FALSE) should return TRUE

Description:
------------
feof(bad_fd) returns FALSE, which indicates that the file descriptor 
has more data.  This is wrong in *every* case.  It should return 
TRUE (no more data), or throw a fatal error.  More than a few sloppy 
fools fail to test the result of fopen(), and blow your bandwidth 
cap and/or hosting budget for a year by serving warnings when your 
RSS source changes their DNS name. 

Reproduce code:
---------------
<?php
$f = fopen ("http://dns.err/foo.html","r");  # ie. $f=FALSE
while (!feof ($f)) {                         # ie. !feof(FALSE)
  $verse .= fgets($f, 4096);
}
fclose ($f);
echo "DONE";


Expected result:
----------------
Warning: fopen(): php_network_getaddresses: getaddrinfo failed: Name 
or service not known in /home/andrewm/x.php on line 2

Warning: fopen(http://dns.err/foo.html): failed to open stream: No 
such file or directory in /home/andrewm/x.php on line 2

Warning: feof(): supplied argument is not a valid stream resource 
in /home/andrewm/x.php on line 3
DONE

Actual result:
--------------
Warning: fopen(): php_network_getaddresses: getaddrinfo failed: Name 
or service not known in /home/andrewm/x.php on line 2

Warning: fopen(http://dns.err/foo.html): failed to open stream: No
