Description:
------------
If strtr(string $str, array $replace_pairs) is called and one of the keys of $replace_pairs is an empty string, strtr will return the boolean value FALSE.  This is not reflected in the documentation.

Test script:
---------------
<?php
var_dump(strtr('foo', array('' => 'nothing')));

Expected result:
----------------
Unsure, is the empty string ever really "found" in a string?

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

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

I've added a note about the function returning false when an empty string key is 
provided. Thanks for the report!
