问题描述
我想使用MVC模式将我的逻辑从表示形式和数据中划分出来。
好，我一直在搜索我。但事实是，我什至不知道要搜索什么。
我正在尝试在php中设置MVC框架。我正在关注youtube上的教程，并且停留在路由点。
我已经阅读了很多指南，每个人都以不同的方式讲课，只会造成更多的混乱。
问题是这样的：
我有一个包含某些指令的.htaccess文件（但问题是我不知道所有这些指令的含义。我从不了解htaccess逻辑）
Options -MultiViews
RewriteEngine On
＃我认为这可以设置网站的基本网址？
RewriteBase /〜caiuscitiriga / mvc / public
＃这是什么意思？
RewriteCond％{REQUEST_FILENAME}！-d
RewriteCond％{REQUEST_FILENAME}！-f
＃这是？！
RewriteRule ^（。+）$ index.php？url = $ 1 [QSA，L]
然后我有以下php脚本：
Index.php
<？php
require_once'../app/init.php';
$ app =新App（）;
init.php
<？php
require_once'core / App.php';
require_once‘core / Controller.php’;
App.php
不要问我为什么使用 filter_var 和 rtrim 。因为这正是我要弄清楚的。如我之前所说，此代码不是我的。我确定诀窍完全在.htacess和App.php中，但我不理解逻辑
class App {
受保护的$ controller ='home';
保护$ method =索引;
受保护的$ params = [];
公共功能__construct（）
{
print_r（$ this-> parseUrl（））;
}
公共函数parseUrl（）
{
if（isset（$ _ GET ['url']））
{
return $ url = explode（'/'，filter_var（rtrim（$ _ GET ['url']，'/'），FILTER_SANITIZE_URL））;
}
}
}
Controller.php
<？php
class Controller {
}
home.php
<？php
类Home扩展控制器{
公共功能index（）
{
echo'home / index';
}
}
如果我通过以下网址： localhost /〜caiuscitiriga / mvc / public / home / index / maxine
我得到了这个：数组（[0] => home [1] => index [ 2] => maxine）
为什么？！？我的意思是，这是正确的。但是为什么呢？
RewriteCond％{REQUEST_FILENAME}！-d
RewriteCond％{REQUEST_FILENAME}！-f
RewriteRule ^（。+）$ index.php？url = $ 1 [QSA，L]
我将以上内容理解为：如果请求不是目录，也不是文件，则采用路径并将其以url属性作为路径在内部传递给index.php。 / p>
所以现在
// example.com/big/bad/妈妈
映射到
//example.com/index.php?url=大/坏/妈妈
您可以根据需要调用上面的脚本。
然后，您的解析网址就是url的值（ big / bad / mamma），删除了如果有斜杠，则以斜杠结尾。然后在遇到正斜杠的任何地方分割字符串。因此，您将分为三个部分。
来自：
FILTER_SANITIZE_URL过滤器将删除除字母，数字和$ -_。+！*！（）外的所有字符，{} | \ ^〜[]`<>＃％; /？：@& =。
但是如果您想了解请分解片段：
$ url = $ _GET ['url'];
var_dump（$ url）;
$ url = rtrim（$ url，'/'）;
var_dump（$ url）;
$ url = filter_var（$ url，FILTER_SANITIZE_URL）;
var_dump（$ url）;
$ url = explode（'/'，$ url）;
var_dump（$ url）;
I want to use the MVC pattern to divide my logic, from the presentation and the data.
Well, i've been searching for i while. But the truth is that i don't even know what to search.
I'm trying to setup a MVC Framework in php. I'm following a tutorial on youtube, and i'm stuck at the routing point.
I've read a LOT of guides, and every single one teaches things in different ways, creating only more confusion.
The point is this:
i have a .htaccess file that contains some directives (but the problem is that i don't know what all those directives means. I've never understood the htaccess logic)
Options -MultiViews
RewriteEngine On
#I think this sets the base url of the site?
RewriteBase /~caiuscitiriga/mvc/public
#What does this mean??
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
#AND THIS?!
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]
And then i have these php scripts:
Index.php
<?php
require_once '../app/init.php';
$app = new App();
init.php
<?php
require_once 'core/App.php';
require_once 'core/Controller.php';
App.php
Don't ask me why i used filter_var and rtrim. Because is exactly what i want to figure out. As i said before, this code isn't mine. I'm sure that the trick it's exactly in .htacess and App.php but i don't understand the logic
class App{
protected $controller = 'home';
protected $method = 'index';
protected $params = [];
public function __construct()
{
print_r($this->parseUrl());
}
public function parseUrl()
{
if(isset($_GET['url']))
{
return $url = explode('/', filter_var(rtrim($_GET['url'], '/'), FILTER_SANITIZE_URL));
}
}
}
Controller.php
<?php
class Controller{
}
home.php
<?php
class Home extends Controller{
public function index()
{
echo 'home/index';
}
}
If i pass this url: localhost/~caiuscitiriga/mvc/public/home/index/maxine
I GET THIS: Array ( [0] => home [1] => index [2] => maxine )
WHY?!!? I mean, it's correct. But why??
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]
I read the above as, if the request is not a directory, and not a file, then take the path and pass it to index.php internally with the url attribute as the path.
So now
//example.com/big/bad/mamma
maps to
//example.com/index.php?url=big/bad/mamma
You could call the script as above if you want.
Then your parse url is taking the value of url ('big/bad/mamma'), removing a trailing slash if there is one. And then splitting the string wherever it encounters a forward slash. So you end up with three parts. Which is what you have in your array.
From the manual:
The FILTER_SANITIZE_URL filter will remove all characters except letters, digits and $-_.+!*'(),{}|\^~[]`<>#%";/?:@&=.
But break it down if you want to understand the pieces:
$url = $_GET['url'];
var_dump($url);
$url = rtrim($url, '/');
var_dump($url);
$url = filter_var($url, FILTER_SANITIZE_URL);
var_dump($url);
$url = explode('/', $url);
var_dump($url);
