Parser throws uninitialized offsets warning when "REPLACE" MySQL function used in SELECT clause

[GoogleCodeExporter]

Hello,

Using the replace function in MySQL (the str_replace of MySQL) in a SELECT 
clause will cause the parser to throw PHP notices & warnings.

Example: Query is :
SELECT test_ID, 
test_name, 
    REPLACE(   test_name  , 'aa', 'bb') AS 'test_name_modified'
FROM  test  
ORDER BY test_name ASC;

I am using php-sql-parser version SVN: $Id: PHPSQLParser.php 757 2013-12-16 
09:54:05Z phosco@gmx.de $
with  PHP  5.4.6


Is there a way around this? It "works" but I like to have a clean output, 
without warnings & notices. 

Thank you!
