Bug description:  fread($fp,0) generates warning

Description:
------------
fread($handle, 0) generates a warning where it did not in earlier
versions.



This typically occurs in situations where the filesize is calculated:

  fread($handle, filesize($filename));



(where $handle is the result of opening file $filename, and $filename is
the name of a zero-byte file)

Reproduce code:
---------------
// Taken from fread documentation, will generate WARNING

// if something.txt exists and is empty (0 bytes)



// get contents of a file into a string

$filename = "/usr/local/something.txt";

$handle = fopen($filename, "r");

$contents = fread($handle, filesize($filename));

fclose($handle);



Expected result:
----------------
Would expect $contents == '', no errors or warnings

Actual result:
--------------
Warning: fread(): Length parameter must be greater than 0. in xx on line
yy
