PHP MVC框架路由学习笔记

# 定义application路径
define(‘APPPATH’, trim(__DIR__,’/'));

# 获得请求地址
$root = $_SERVER['SCRIPT_NAME'];
$request = $_SERVER['REQUEST_URI'];

$URI = array();

# 获得index.php 后面的地址
$url = trim(str_replace($root, ”, $request), ‘/’);

# 如果为空，则是访问根地址
if (empty($url))
{
# 默认控制器和默认方法
$class = ‘index’;
$func = ‘welcome’;
}
else
{
$URI = explode(‘/’, $url);

# 如果function为空 则默认访问index
if (count($URI) < 2)
{
$class = $URI[0];
$func = ‘index’;
}
else
{
$class = $URI[0];
$func = $URI[1];
}
}


# 把class加载进来
include(APPPATH . ‘/’ . ‘application/controllers/’ . $class . ‘.php’);

#实例化
$obj = new ucfirst($class);

call_user_func_array(
# 调用内部function
array($obj,$func),
# 传递参数
array_slice($URI, 2)
);

class Index
{

function welcome()
{
echo ‘I am default controller’;
}

}


?>

hello.php

class Hello
{
public function index()
{
echo ‘hello world’;
}

public function name($name)
{
echo ‘hello ‘ . $name;
}
}

?>
