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
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;
}
}
