Bug description: feof() doesn't return TRUE when invalid file handle is passed to it
Description:
------------
When a fopen() is done on a file that has permissions that are set to not
allow the current process user to read it or the file doesn't exist it
returns false. This is expected. The problem is when feof() is fed the
invalid handle it doesn't return TRUE() thus creating an infinite loop in
the following code example.
Reproduce code:
---------------
<?php
$fp = fopen( 't.txt', 'r' );
while( !feof( $fp ) )
{
print fgets( $fp );
}
fclose( $fp );
?>
Expected result:
----------------
feof() would return TRUE to cancel the loop and the script would end.
There would of course be warnings because of the invalid file handle, but
that is expected.
There should be better error handling on the developers part and catch the
invalid file handle, but I would expect the file functions to handle this
situation accordingly.
Actual result:
--------------
Inifinite loop
