The row to be accessed. This parameter can only be used if the specified

can take on one of the following values:

<para>
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>.
