一、原始数据
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 | function getDatas(){ return [ [ 'component' => 'system', 'redict' => '/system', 'path' => '/system', 'hidden' => 1, 'name' => '系统管理', 'children' => [ [ 'component' => 'user', 'redict' => '/user', 'path' => '/user', 'hidden' => 1, 'name' => '用户管理', 'children' => [ [ 'component' => 'user_list', 'redict' => '/user_list', 'path' => '/user_list', 'hidden' => 1, 'name' => '用户列表', ], [ 'component' => 'role', 'redict' => '/user_role', 'path' => '/user_role', 'hidden' => 1, 'name' => '角色列表', ], [ 'component' => 'perm', 'redict' => '/perm', 'path' => '/perm', 'hidden' => 1, 'name' => '权限列表', ], ] ], [ 'component' => 'data', 'redict' => '/data', 'path' => '/data', 'hidden' => 1, 'name' => '数据管理', 'children' => [ [ 'component' => 'report', 'redict' => '/report', 'path' => '/report', 'hidden' => 1, 'name' => '分日报表', ], [ 'component' => 'hour_report', 'redict' => '/hour_report', 'path' => '/hour_report', 'hidden' => 1, 'name' => '分时报表', ], [ 'component' => 'month_report', 'redict' => '/month_report', 'path' => '/month_report', 'hidden' => 1, 'name' => '分月报表', ], ] ], [ 'component' => 'resource', 'redict' => '/resource', 'path' => '/resource', 'hidden' => 1, 'name' => '资源管理', 'children' => [ [ 'component' => 'res_list', 'redict' => '/res_list', 'path' => '/res_list', 'hidden' => 1, 'name' => '资源列表' ] ] ] ] ]]} |
二、函数处理
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 | function deal(){ $datas = getDatas(); $level_1_tree = []; foreach($datas as $data_level_1){ $data_level_1_arr['component'] = $data_level_1['component']; $data_level_1_arr['redict'] = $data_level_1['redict']; $data_level_1_arr['path'] = $data_level_1['path']; $data_level_1_arr['meta'] = [ 'title' => $data_level_1['name'], 'hidden' => $data_level_1['hidden'] ]; $level_2_tree = []; if(isset($data_level_1['children']) && !empty($data_level_1['children'])) { foreach ($data_level_1['children'] as $data_level_2) { $data_level_2_arr['component'] = $data_level_2['component']; $data_level_2_arr['redict'] = $data_level_2['redict']; $data_level_2_arr['path'] = $data_level_2['path']; $data_level_2_arr['meta'] = [ 'title' => $data_level_2['name'], 'hidden' => $data_level_2['hidden'] ]; $level_3_tree = []; if (isset($data_level_2['children']) && !empty($data_level_2['children'])) { foreach ($data_level_2['children'] as $data_level_3) { $data_level_3_arr['component'] = $data_level_3['component']; $data_level_3_arr['redict'] = $data_level_3['redict']; $data_level_3_arr['path'] = $data_level_3['path']; $data_level_3_arr['meta'] = [ 'title' => $data_level_3['name'], 'hidden' => $data_level_3['hidden'] ]; array_push($level_3_tree, $data_level_3_arr); unset($data_level_3_arr); } $data_level_2_arr['children'] = $level_3_tree; } array_push($level_2_tree, $data_level_2_arr); unset($data_level_2_arr); } $data_level_1_arr['children'] = $level_2_tree; } array_push($level_1_tree, $data_level_1_arr); unset($data_level_1_arr); } print_r($level_1_tree); } deal(); |
三、方法补充
除了上文的方法，小编还为大家整理了PHP处理三级分类数据的其他方法，希望对大家有所帮助
示例代码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | query("SET NAMES utf8");$sql = "select * from tp_goods_categorys";$res = mysqli_query($link,$sql);while($res && $row = mysqli_fetch_assoc($res)) { $list[] = $row;}echo '<pre>';print_r(res($list)); function res($items){ $tree = array(); foreach($items as $key =>$val){ $list = explode(',',$val['categorys_path']); switch(count($list)){ case 1: $tree[$val['id']] = $val; break; case 2: $tree[$val['categorys_pid']]['son'][$val['id']] = $val; break; case 3: $tree[$list[1]]['son'][$list[2]]['son'] = $val; break; } } return $tree;}</pre> |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | 1, 'pid' => 0, 'name' => '湖北省'),array('id' => 2, 'pid' => 0, 'name' => '北京市'),array('id' => 3, 'pid' => 1, 'name' => '武汉市'),array('id' => 4, 'pid' => 2, 'name' => '朝阳区'),array('id' => 5, 'pid' => 2, 'name' => '通州区'),array('id' => 6, 'pid' => 4, 'name' => '望京'),array('id' => 7, 'pid' => 4, 'name' => '酒仙桥'),array('id' => 8, 'pid' => 3, 'name' => '武昌区'),array('id' => 9, 'pid' => 1, 'name' => '武安市'),);function cation($arr,$num=0,$m=1){ $list = []; foreach($arr as $k=>$v){ if($v['pid'] === $num){ $v['level'] = $m; $v['son'] = cation($arr,$v['id'],$m+1); $list[] = $v; } } return $list;}$list = cation($array);echo '<pre>';print_r($list);echo '</pre><p>';</p> |
另一种需求
（重组一维数组）
1 2 3 4 5 6 7 8 | // 处理分类数据 栏目分级 public function allMenu($cates,$pid=0,$level=0){ static $cateArr = array(); for($i=0;$iallMenu($cates,$cates[$i]['id'],$level+1); } } return $cateArr; } |
