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;
}
}
希望本文所述对大家学习PHP程序设计有所帮助。
