Required to Trim Variables with MSSQL Module

Hi all, I've got a rather iritating problem. I recently moved a site from PHP 3.0.11 to 4.0.5 RC1. It seems, and I have noticed this for a while in other scripts, that variables returned from MSSQL sometimes need to be trimmed with trim() in order to function correctly. Sometimes they won't evaluate as integers (i.e. they don't add right), other times they don't evaluate right as strings (i.e. with if (!$row[crap]), and other times if I have a header redirect (i.e. Header("Location: ./index.php?crap=$row[crap]") ) I get the infamous CGI header problem. I generally retrieve with $row = mssql_fetch_array($result); In all cases adding trim will fix the problem. Anyone had similar problems. Am I missing something. This seems to be odd behavior. I really don't want to go through all my scripts and trip stuff. Thanks, -Flint
