一个简单的php路由类

本文实例为大家分享了php编写一个简单的路由类，供大家参考，具体内容如下

    <?php
    namespace cmhc\Hcrail;

    class Hcrail
    {

      /**
       * callback function
       * @var callable
       */
      protected static $callback;

      /**
       * match string or match regexp
       * @var string
       */
      protected static $match;

      protected static $routeFound = false;

      /**
       * deal with get,post,head,put,delete,options,head
       * @param  $method
       * @param  $arguments
       * @return
       */
      public static function __callstatic($method, $arguments)
      {
        self::$match = str_replace("//", "/", dirname($_SERVER['PHP_SELF']) . '/' . $arguments[0]);
        self::$callback = $arguments[1];
        self::dispatch();
        return;
      }

      /**
       * processing ordinary route matches
       * @param string $requestUri
       * @return
       */
      public static function normalMatch($requestUri)
      {
        if (self::$match == $requestUri) {
          self::$routeFound = true;
          call_user_func(self::$callback);
        }
        return;
      }

      /**
       * processing regular route matches
       * @param string $requestUri
       * @return
       */
      public static function regexpMatch($requestUri)
      {
        //处理正则表达式
        $regexp = self::$match;
        preg_match("#$regexp#", $requestUri, $matches);
        if (!empty($matches)) {
          self::$routeFound = true;
          call_user_func(self::$callback, $matches);
        }
        return;
      }

      /**
       * dispatch route
       * @return
       */
      public static function dispatch()
      {
        if (self::$routeFound) {
          return ;
        }
        $requestUri = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
        $requestMethod = $_SERVER['REQUEST_METHOD'];

        if (strpos(self::$match, '(') === false) {
          self::normalMatch($requestUri);
        } else {
          self::regexpMatch($requestUri);
        }

      }

      /**
       * Determining whether the route is found
       * @return boolean
       */
      public static function isNotFound()
      {
        return !self::$routeFound;
      }

    }
