一、原始数据

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

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();
