Description:
------------
The real behaviour is different from the one which is described in the docs. 

The docs says: "If string is less than start characters long, FALSE will be returned." In the case of the parameters described below, the string "abc" is not less than 3 characters long so it should NOT give back FALSE, but it gives. 

Reproduce code:
---------------
  var_dump( substr( "abc", 3, 0 ) );


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



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

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Ehm the string \"abc\" has no [3], we start counting at 0.

\"If start is non-negative, the returned string will start at the start\'th position in string, counting from zero.\"

Well, it's OK, the characters are counted from 0, but the sentence below is not true:
"If string is less than start characters long, FALSE will
be returned."
The true version should be:
"False is returned if string is less OR EQUAL than start characters long." Shouldn't it?
