I have found the cause of the issue and the solution:

Buried away in the mssql_field_length documentation is an important limitation that it is certainly worth knowing about *BEFORE* you do any database design:
Note to Win32 Users: Due to a limitation in the underlying API used by PHP (MS DbLib C API), the length of VARCHAR fields is limited to 255. If you need to store more data, use a TEXT field instead.
SQL Server natively supports VARCHAR up to 8000 characters. Note that TEXT fields have substantially poorer performance (and are much more limited) than VARCHAR so you may want to design your databases accordingly...
You can also work around this limitation with the following:
-- for example, with MyVarCharField VARCHAR(1000)
SELECT CAST(MyVarCharField AS TEXT) FROM MyTable
