       The row to be accessed. This parameter can only be used if the specified 
       statement was prepared with a scrollable cursor. In that case, this parameter 
       can take on one of the following values:

        <member>SQLSRV_SCROLL_PRIOR</member>

   If a class name is specified with the optional $className parameter and the 
   class has properties whose names match the result set field names, the corresponding 
   result set values are applied to the properties. If a result set field name 
   does not match a class property, a property with the result set field name is added 
   to the object and the result set value is applied to the property. The following 
   rules apply when using the $className parameter:
   <simplelist>
      <member>Field-property name matching is case-sensitive.</member>
      <member>Field-property matching occurs regardless of access modifiers.</member>
      <member>Class property data types are ignored when applying a field value to a property.</member>
      <member>If the class does not exist, the function returns &false; and adds an error to the error collection.</member>
   </simplelist>
   Regardless of whether the $className parameter is supplied, if a field with no 
   name is returned, the field value will be ignored and a warning will be added 
   to the error collection.
  </para>
  <para>
   When consuming a result set that has multiple columns with the same name, it may 
   be better to use <function>sqlsrv_fetch_array</function> or the combination of 
   <function>sqlsrv_fetch</function> and <function>sqlsrv_get_field</function>.
