中间件的实现朱自清背影读后感原理

运用 array_reduce 以及 call_ur_func 实现

interface middleware{    public static function handle(closure $next);}class verfiycsrftoekn implements milldeware{     public 炒面条static function handle(closure $next) {         echo '验证csrf token <br>';         $next();     }}class verfiyauth implements milldeware{    public static function handle(closure $next) {         echo '验证是否留侯论翻译登录 <br>';         $next();     }}class t西元前cookie implements milldeware{     public static fun会计学专业就业ction handle(closure $next) {         $next();         echo '设置cookie信息！';     }}$handle = function () {     echo '当前要执行的程序!';};$pipe_arr = [ 'verfiycsrftoekn', 'verfiyauth', 'tcookie', ];$callback = array_reduce($pipe_arr, function ($stack, $pipe) {    return function () u ($stack, $pipe) {        return $pipe::handle($stack);    };}, $handle);call_ur_func($callback);
