Description
string 
fbsql_field_name ( resource result, int field_index)
     fbsql_field_name() returns the name of the
     specified field index. result must be a
     valid result identifier and field_index is
     the numerical offset of the field.

      e.g. The index of the third field would actually be 2, the index
      of the fourth field would be 3 and so on.
