簡單的PHP MVC框架
\application\models\front.php
代碼如下
<?php
class FrontController {
protected $_controller, $_action, $_params, $_body;
static $_instance;
public static function getInstance() {
if( ! (self::$_instance instanceof self) ) {
self::$_instance = new self();
}
return self::$_instance;
}
private function __construct() {
$request = $_SERVER['REQUEST_URI'];
$splits = explode('/', trim($request,'/'));
$this->_controller = !empty($splits[0])?$splits[0]:'index';
$this->_action = !empty($splits[1])?$splits[1]:'index';
if(!empty($splits[2])) {
$keys = $values = array();
for($idx=2, $cnt = count($splits); $idx<$cnt; $idx++) {
if($idx % 2 == 0) {
//Is even, is key
$keys[] = $splits[$idx];
} else {
//Is odd, is value;
$values[] = $splits[$idx];
}
}
$this->_params = array_combine($keys, $values);
}
}
public function route() {
if(class_exists($this->getController())) {
$rc = new ReflectionClass($this->getController());
if($rc->implementsInterface('IController')) {
if($rc->hasMethod($this->getAction())) {
$controller = $rc->newInstance();
$method = $rc->getMethod($this->getAction());
$method->invoke($controller);
} else {
throw new Exception("Action");
}
} else {
throw new Exception("Interface");
}
} else {
throw new Exception("Controller");
}
}
public function getParams() {
return $this->_params;
}
public function getController() {
return $this->_controller;
}
public function getAction() {
return $this->_action;
}
public function getBody() {
return $this->_body;
}
public function setBody($body) {
$this->_body = $body;
}
}
\application\models\view.php
代碼如下
<?php
class View extends ArrayObject {
public function __construct() {
parent::__construct(array(), ArrayObject::ARRAY_AS_PROPS);
}
public function render($file) {
ob_start();
include(dirname(__FILE__) . '/' . $file);
return ob_get_clean();
}
}
application\models\icontroller.php
代碼如下
<?php
interface IController {}
