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;

  }

 

}
