这里利用数组来做实例,有需要的要改成数据库查询然后再存到数据操作,实例代码如下:
array( 'aaaaaa' => array( '111111', '222222', '333333' ), 'bbbbbb' => array( '111111', '222222', '333333' ), 'cccccc' => array( '111111', '222222', '333333' ), ), 'bbbbbb' => array( 'aaaaaa' => array( '111111', '222222', '333333' ), 'bbbbbb'=> array( '111111', '222222', '333333' ), 'cccccc'=> array( '111111', '222222', '333333' ), ), 'cccccc' => array( 'aaaaaa'=> array( '111111', '222222', '333333' ), 'bbbbbb'=> array( '111111', '222222', '333333' ), 'cccccc' => array( '111111', '222222', '333333' ), ), ); foreach ($a as $k=>$v){ echo $k.
; // if(is_array($v)){ foreach($v as $key=>$val){ echo .$key.
; // } if(is_array($val)){ foreach($val as $kkk=>$vall){ echo .$vall.
; } } } echo
; } /*******mysql查询无限级分类的代码******/ /*** $sql = select a.title as big, b.title as small from largetitle as a left join smalltitle as b on a.id=b.largeid; $a = array(); $r = mysql_query($sql); while( $arr = mysql_fetch_array($r)){ $a[$arr['big']] = $arr['small']; } ***/
