根据分类父id 递归查询父类别 结果放入二维数组中
//$db 为一个数据库对象 function get_array($pid,$db){ global $category; $sql = " select * from yl_category where id = " . $pid; $res = $db->query($sql); //查询返回所有结果 if (! empty($res)) { $category[] = $res[0]; return get_array($res[0]['pid'],$db); }else { return $category; } } if (! empty($pid)) { $category = get_array($pid,$db); } $category = array_reverse($category); //反转数组 echo '<pre>'; print_r($category);exit;返回结果
Array ( [0] => Array ( [id] => 1 [category_name] => 22223331 [pid] => 0 [orders] => 1 ) [1] => Array ( [id] => 2 [category_name] => 2222111 [pid] => 1 [orders] => 1 ) [2] => Array ( [id] => 11 [category_name] => 333 [pid] => 2 [orders] => 0 ) )
