    } // Loop for $i
     reset( $dsql3);

     return $likeType;
}

二、在模板调用
实例：

{dede:channel type='son' typeid='22'}
              [field:typename/]
                     < ul >
                    [field:sonchannel0]
                     < li >< a href ="http://www.skyey.com.cn/[field:typelink/]" >[field:typename/] </ a ></ li >
                         [field:sonchannel1]
                         < li >< a href ="http://www.skyey.com.cn/[field:typelink/]" >---[field:typename/] </ a ></ li >
                             [field:sonchannel2]
                             < li >< a href ="http://www.skyey.com.cn/[field:typelink/]" >===[field:typename/] </ a ></ li >
                                [field:sonchannel3]
                                 < li >< a href ="http://www.skyey.com.cn/[field:typelink/]" >===[field:typename/] </ a ></ li >
                                 [/field:sonchannel3]
                             [/field:sonchannel2]
                         [/field:sonchannel1]
                    [/field:sonchannel0]
                     </ ul >

{/dede:channel}

模板调用 [field:sonchannel0] [/field:sonchannel0] 这个是用来取子栏目用得（使用[sonchannel+数字] 作为标签名是为了防止嵌套的时候无法正确解析标签）
这个的作用就是当你的栏目有很多子栏目无限分级的时候方便你取子栏目的
