Are you sure you're getting the number as you need it from the query?
PHP won't (though I guess there could be a bug) automatically convert a
numerical string into it's numerical equivalent.
If the code you posted produces this problem, then the only possiblities
I see are that the mssql module is returning a number, or the database
query is returning that particular string.
