我认为最好将所有请求重定向到 index.php 文件，然后使用 php 提取控制器名称和任何其他参数。与 Zend Framework 等任何其他框架相同。
这是一个简单的类，可以做你想做的事。
class HttpRequest
{
/**
* default controller class
*/
const CONTROLLER_CLASSNAME = 'Index';
/**
* position of controller
*/
protected $controllerkey = 0;
/**
* site base url
*/
protected $baseUrl;
/**
* current controller class name
*/
protected $controllerClassName;
/**
* list of all parameters $_GET and $_POST
*/
protected $parameters;
public function __construct()
{
// set defaults
$this->controllerClassName = self::CONTROLLER_CLASSNAME;
}
public function setBaseUrl($url)
{
$this->baseUrl = $url;
return $this;
}
public function setParameters($params)
{
$this->parameters = $params;
return $this;
}
public function getParameters()
{
if ($this->parameters == null) {
$this->parameters = array();
}
return $this->parameters;
}
public function getControllerClassName()
{
return $this->controllerClassName;
}
/**
* get value of $_GET or $_POST. $_POST override the same parameter in $_GET
*
* @param type $name
* @param type $default
* @param type $filter
* @return type
*/
public function getParam($name, $default = null)
{
if (isset($this->parameters[$name])) {
return $this->parameters[$name];
}
return $default;
}
public function getRequestUri()
{
if (!isset($_SERVER['REQUEST_URI'])) {
return '';
}
$uri = $_SERVER['REQUEST_URI'];
$uri = trim(str_replace($this->baseUrl, '', $uri), '/');
return $uri;
}
public function createRequest()
{
$uri = $this->getRequestUri();
// Uri parts
$uriParts = explode('/', $uri);
// if we are in index page
if (!isset($uriParts[$this->controllerkey])) {
return $this;
}
// format the controller class name
$this->controllerClassName = $this->formatControllerName($uriParts[$this->controllerkey]);
// remove controller name from uri
unset($uriParts[$this->controllerkey]);
// if there are no parameters left
if (empty($uriParts)) {
return $this;
}
// find and setup parameters starting from $_GET to $_POST
$i = 0;
$keyName = '';
foreach ($uriParts as $key => $value) {
if ($i == 0) {
$this->parameters[$value] = '';
$keyName = $value;
$i = 1;
} else {
$this->parameters[$keyName] = $value;
$i = 0;
}
}
// now add $_POST data
if ($_POST) {
foreach ($_POST as $postKey => $postData) {
$this->parameters[$postKey] = $postData;
}
}
return $this;
}
/**
* word seperator is '-'
* convert the string from dash seperator to camel case
*
* @param type $unformatted
* @return type
*/
protected function formatControllerName($unformatted)
{
if (strpos($unformatted, '-') !== false) {
$formattedName = array_map('ucwords', explode('-', $unformatted));
$formattedName = join('', $formattedName);
} else {
// string is one word
$formattedName = ucwords($unformatted);
}
// if the string starts with number
if (is_numeric(substr($formattedName, 0, 1))) {
$part = $part == $this->controllerkey ? 'controller' : 'action';
throw new Exception('Incorrect ' . $part . ' name "' . $formattedName . '".');
}
return ltrim($formattedName, '_');
}
}
如何使用：
$request = new HttpRequest();
$request->setBaseUrl('/your/base/url/');
$request->createRequest();
echo $request->getControllerClassName(); // return controller name. Controller name separated by '-' is going to be converted to camel case.
var_dump ($request->getParameters()); // print all other parameters $_GET & $_POST
