我有一个路由机制，通过依赖文件系统结构来发送请求：

function Route($root) {
  $root = realpath($root) . '/';
  $segments = array_filter(explode('/',
    substr($_SERVER['PHP_SELF'], strlen($_SERVER['SCRIPT_NAME']))
  ), 'strlen');

  if ((count($segments) == 0) || (is_dir($root) === false)) {
    return true; // serve index
  }

  $controller = null;
  $segments = array_values($segments);

  while ((is_null($segment = array_shift($segments)) !== true)
    && (is_dir($root . $controller . $segment . '/'))) {
      $controller .= $segment . '/';
  }

  if ((is_file($controller = $root . $controller . $segment . '.php')) {
    $class = basename($controller . '.php');
    $method = array_shift($segments) ?: $_SERVER['REQUEST_METHOD'];

    require($controller);

    if (method_exists($class = new $class(), $method)) {
      return call_user_func_array(array($class, $method), $segments);
    }
  }

  throw new Exception('/' . implode('/', self::Segment()), 404); // serve 404
}

- /controllers
  - /admin
    - /company
      - /edit.php   (has get() & post() methods)
    - /company.php  (has get($id = null) method)

最佳答案

对于像这样关键的东西，用phpunit这样的测试框架编写测试非常重要。
按此处所述安装（您需要PEAR）：
https://github.com/sebastianbergmann/phpunit/
我还使用虚拟文件系统，这样您的测试文件夹就不会变得凌乱：https://github.com/mikey179/vfsStream/wiki/Install
我只是把route函数放到了一个名为Route.php的文件中。在同一个目录中，我现在创建了一个test.php文件，其中包含以下内容：

<?php

require_once 'Route.php';

class RouteTest extends PHPUnit_Framework_TestCase {
}

$ cd path/to/directory
$ phpunit test.php
