From manual page: http://www.php.net/function.substr#refsect1-function.substr-
description

Truncating an entire string should result in a string.

When $start is equal to strlen($string), an empty string should be returned 
instead of FALSE.

Test script:
---------------
var_dump(substr("", 0));
var_dump(substr("a", 1));
var_dump(substr("ab", 2));



Expected result:
----------------
string(0) ""
string(0) ""
string(0) ""

Actual result:
--------------
bool(false)
bool(false)
bool(false)
