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

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;

}

}

希望本文所述对大家学习PHP程序设计有所帮助。
