If possible, take the return from mssql_init() and check it for boolean
false. If it is, try to trap the error returned from the server with
mssql_get_last_message(). All of the errors you see after the mssql_init()
failure are because you are trying to pass a boolean value (in this case, a
FALSE) to functions that expect an initialized stored proc resource handle.
