 New Comment:

feof() of PHP is the same of feof in C, and i think that the best
definition is this: (taken from
http://msdn2.microsoft.com/en-us/library/xssktc6e(VS.71).aspx):
"The feof function returns a nonzero value after the first read
operation that attempts to read past the end of the file. It returns 0
if the current position is not end of file. There is no error return."

So if you add an additional fgetc(), it should work:
var_dump( ftell($fh) );
var_dump( fseek($fh, 0, SEEK_END) );
var_dump( ftell($fh) );
var_dump( fgetc($fh) );
var_dump( feof($fh) );

I observed that when I use fgetcsv() to read a file to end, and then
check for EOF, feof() returns true. Hence I suspect the problem is with
fseek() that although it succceeds in taking the file pointer to EOF but
fails to set the EOF flag.

Description:
------------
feof() is not able to detect the end of file even when the file pointer
is set to EOF using fseek() or any other ways. If we use the sample code
similar to that given in the help docs for feof() on php.net:

<?php          
$fh = fopen("file.tmp", "w");
fclose($fh);
$fh = fopen("file.tmp", "r");
while(!feof()){
}
fclose($fh);
unlink("file.tmp");
?>

The code runs to endless loop as feof donot detect the EOF.

Reproduce code:
---------------
<?php          
$fh = fopen("file.tmp", "w");
fwrite($fh, "aaa");
fclose($fh);
$fh = fopen("file.tmp", "r");
var_dump( ftell($fh) );
var_dump( fseek($fh, 0, SEEK_END) );
var_dump( ftell($fh) );
var_dump( feof($fh) );
fclose($fh);
unlink("file.tmp");
?>

Expected result:
----------------
int(0)
int(0)
int(3)
bool(true)

Actual result:
--------------
int(0)
int(0)
int(3)
bool(false)
