I wish to move all files out of public folder except "index.php" & "assets." I'm slowly updating to a custom MVC for my small project: I've moved functions, config & classes etc. - it's just the old spaghetti PHP files left. I want to move them all before I start breaking them down into models, views etc.
I would prefer core PHP and not to use symfony if any one can help.
So, instead of all files been on same level as "index.php" everything would route to new folder with all the files and new "index2.php" - so I've used a simple way that works on some level but there are 30 files, and I do not wish to write each one out if there's a better way.
htaccess:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+)$ index.php [QSA,L]
index.php:
<?php
$request = $_SERVER['REQUEST_URI'];
switch ($request) {
case '/' :
require __DIR__ . '/app/memberlist.php';
break;
case '' :
require __DIR__ . '/app/memberlist.php';
break;
case '/staff' :
require __DIR__ . '/app/staff.php';
break;
default:
http_response_code(404);
require __DIR__ . 'app/pdointro.php';
break;
}
Also there are some paths in the file I don't know how to add like:
header("Location: account-details.php?id=$id");
and:
<a href='account.php?action=edit_settings&do=edit'>edit</a>
Nice you choose front controller design pattern. I think you could create an array with all your php files dynamically and then make a comparison with REQUEST_URI.
Take a look at php docs:
https://www.php.net/manual/fr/class.recursivedirectoryiterator.php
https://www.php.net/manual/fr/class.recursiveiteratoriterator.php
https://www.php.net/manual/fr/class.recursivecallbackfilteriterator.php (to add filter)
Example below :
$files = [];
$dirIterator = new \RecursiveDirectoryIterator(
'your_php_project_root_dir',
\FilesystemIterator::SKIP_DOTS | \FilesystemIterator::KEY_AS_PATHNAME |
\FilesystemIterator::CURRENT_AS_SELF
);
$fileIterator = new \RecursiveIteratorIterator($dirIterator);
foreach($fileIterator as $file) {
$filePath = $file->getPathName();
$fileExt = $file->getExtension();
$fileName = $file->getFileName();
$fileSubPath = $file->getSubPath();
$isFile = $file->isFile();
// here you can filter, make condition and then add php files to your array.
// $files[$fileName]
}
if ($path = \array_search($_SERVER['REQUEST_URI'], $files)) {
require($path);
}
exit;
This is an idea of what you could do.
My current router / FrontController is setup to dissect URL's in the format:
http://localhost/controller/method/arg1/arg2/etc...
However, I'm not sure how to get certain requests to default to the IndexController so that I can type:
http://localhost/contact
or
http://localhost/about/portfolio
Instead of:
http://localhost/index/contact
or
http://localhost/index/about/portfolio
How is this accomplished?
<?php
namespace framework;
class FrontController {
const DEFAULT_CONTROLLER = 'framework\controllers\IndexController';
const DEFAULT_METHOD = 'index';
public $controller = self::DEFAULT_CONTROLLER;
public $method = self::DEFAULT_METHOD;
public $params = array();
public $model;
public $view;
function __construct() {
$this->model = new ModelFactory();
$this->view = new View();
}
// route request to the appropriate controller
public function route() {
// get request path
$basePath = trim(substr(PUBLIC_PATH, strlen($_SERVER['DOCUMENT_ROOT'])), '/') . '/';
$path = trim(parse_url($_SERVER["REQUEST_URI"], PHP_URL_PATH), '/');
if($basePath != '/' && strpos($path, $basePath) === 0) {
$path = substr($path, strlen($basePath));
}
// determine what action to take
#list($controller, $method, $params) = explode('/', $path, 3);
if(isset($controller, $method)) {
$obj = __NAMESPACE__ . '\\controllers\\' . ucfirst(strtolower($controller)) . 'Controller';
$interface = __NAMESPACE__ . '\\controllers\\' . 'InterfaceController';
// make sure a properly implemented controller and corresponding method exists
if(class_exists($obj) && method_exists($obj, $method) && in_array($interface, class_implements($obj))) {
$this->controller = $obj;
$this->method = $method;
if(isset($params)) {
$this->params = explode('/', $params);
}
}
}
// make sure we have the appropriate number of arguments
$args = new \ReflectionMethod($this->controller, $this->method);
$totalArgs = count($this->params);
if($totalArgs >= $args->getNumberOfRequiredParameters() && $totalArgs <= $args->getNumberOfParameters()) {
call_user_func_array(array(new $this->controller, $this->method), $this->params);
} else {
$this->view->load('404');
}
}
}
You can use your URLs by one of two methods:
Establish the controllers the way your routing defines them
example.com/contact => Have a "contact" controller with default or index action
example.com/about/portfolio => Have an "about" controller with a "portfolio" action
Because your currently available routing says your URL is treated like "/controller/method", there is no other way.
Establish dynamic routing to allow multiple URLs to be handled by a single controller
Obviously this needs a bit of configuration because one cannot know which URLs are valid and which one should be redirected to the generic controller, and which ones should not. This is somehow a replacement for any of the rewriting or redirecting solutions, but as it is handled on the PHP level, change might be easier to handle (some webserver configurations do not offer .htaccess because of performance reasons, and it generally is more effort to create these).
Your configuration input is:
The URL you want to be handled and
The controller you want the URL passed to, and it's action.
You'll end up having an array structure like this:
$specialRoutes = array(
"/contact" => "IndexController::indexAction",
"/about/portfolio" => "IndexController::indexAction"
);
What's missing is that this action should get the current URL passed as a parameter, or that the path parts become designated parameters within your URL schema.
All in all this approach is a lot harder to code. To get an idea, try to look at the routing of common MVC frameworks, like Symfony and Zend Framework. They offer highly configurable routing, and because of this, the routing takes place in multiple classes. The main router only reads the configuration and then passes the routing of any URL to the configured routers if a match is detected.
Based on your code snippet I'd do it like this (pseudo php code):
$handler = get_controller($controller);
if(!$handler && ($alias = lookup_alias($path))) {
list($handler, $method) = $alias;
}
if(!$handler) error_404();
function lookup_alias($path) {
foreach(ALL_CONTROLLERS as $controller) {
if(($alias = $controller->get_alias($path))) {
return $alias;
}
}
return null;
}
So basically in case there is no controller to handle a certain location you check if any controller is configured to handle the given path as an alias and if yes return that controller and the method it maps to.
You can create a rewrite in your webserver for these exceptions. For example:
RewriteRule ^contact$ /index/contact
RewriteRule ^about/portfolio$ /about/portfolio
This will allow you to have simplified URLs that map to your regular structure.
You could have a dynamic rule if you are able to precisely define what should be rewritten to /index. For example:
RewriteRule ^([a-z]+)$ /index/$1
Try this dynamic htaccess rewrite rule:
RewriteRule ^(.+)/?$ /index/$1 [QSA]
The QSA flag in the above rule allows you to also add a query string to the end if you want, like this:
http://localhost/contact?arg1=1&arg2=2
EDIT: This rule would also handle cases such as /about/portfolio:
RewriteRule ^(.+)/?(.+)?$ /index/$1 [QSA]
I'm creating a PHP Framework and I have some doubts...
The framework takes the url in this way:
http:/web.com/site/index
It takes the first parameter to load controller (site) and then loads the specific action (index).
If you've installed the framework in a base URL works ok, but if you install it in a subfolder like this:
http://web.com/mysubfolder/controller/action
My script parses it as controller = mysubfolder and action = controller.
If you have more subfolders the results will be worst.
This is my Route code:
Class Route
{
private $_htaccess = TRUE;
private $_suffix = ".jsp";
public function params()
{
$url='';
//nombre del directorio actual del script ejecutandose.
//basename(dirname($_SERVER['SCRIPT_FILENAME']));
if($this->_htaccess !== FALSE):
//no está funcionando bien si está en un subdirectorio web, por ej stynat.dyndns.org/subdir/
// muestra el "subdir" como primer parámetro
$url = $_SERVER['REQUEST_URI'];
if(isset($_SERVER['QUERY_STRING']) && !empty($_SERVER['QUERY_STRING'])):
$url = str_replace("?" . $_SERVER['QUERY_STRING'], '',$url);
endif;
else:
if(isset($_SERVER['PATH_INFO'])):
$url = $_SERVER['PATH_INFO'];
endif;
endif;
$url = explode('/',preg_replace('/^(\/)/','',$url));
var_dump($url);
var_dump($_GET);
}
}
Thanks for any help you can give.
You are missing a base path. The routing script must now where to start when detecting a pattern or route detected.
Pseudo code:
//set the base URI
$base_uri = '/base';
//remove the base URI from the original uri. You can also REGEX or string match against it if you want
$route_uri = str_replace($base_uri,'',$uri);
//perform route matching $route_uri, in your code a simple explode
$url = explode('/',preg_replace('/^(\/)/','',$route_uri));
You can use this with or without RewriteBase for your .htaccess so long as they use the same harness - index.php.
Additionally, you can improve your route match procedure using Regular Expressions function like preg_match and preg_match_all. They let you define a pattern to match against and results to an array of matching strings - see http://php.net/manual/en/function.preg-match.php.
Even if you are creating your own framework, there is no reason not to reuse robust, well tested and documented components, like this Routing component.
Just use Composer, which has become the standard for dependency management in PHP, and you'll be fine. Add as many components as you want to your stack.
And here you have a must read guide on how to make your own framework.
Yes, I think I know how to fix that.
(Disclaimer: I know that you know most of this but I am going to explain everything for others who may not know some of the gotchas)
Using PATH_INFO and .htaccess
There is a trick in php where if you go to a path like:
http://web.com/mysubfolder/index.php/controller/action
you will get "/controller/action" in the $_SERVER['PATH_INFO'] variable
Now what you need to do is take a .htaccess file (or equivalent) and make it tell your php script the current folder depth.
To do this, put the .htaccess file into the "mysubfolder"
mysubfolder
.htaccess
index.php
.htaccess should contain:
RewriteEngine on
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule (.*) index.php/$1
(I used the yii framework manual as reference, I also recommend using the html5 boilerplate)
Basically you set it up to redirect everything to index.php at a specific point in the url.
Now if you visit: http://web.com/mysubfolder/index.php/controller/action
Now you can get the right path "/controller/action" from $_SERVER['PATH_INFO']
Except it's not going to have any value if you visit http://web.com/mysubfolder/ because the .htaccess file will ignore the rewrite because the http://web.com/mysubfolder/ path requests the mysubfolder/index.php which actually exists and gets denied thank yo RewriteCond %{REQUEST_FILENAME} !-f.
ifsetor function
For this you can use this super handy function called ifsetor (I don't remember where I got it)
function ifsetor(&$variable, $default = null) {
return isset($variable)? $variable: $default;
}
What it does is take a reference to a variable that might or might not exist and provide a default if it does not exist without throwing any notices or errors
Now you can use it to take the PATH_INFO variable safely like so
In your index.php
function ifsetor(&$variable, $default = null) {
return isset($variable)? $variable: $default;
}
$path = ifsetor($_SERVER['PATH_INFO'],'/');
var_dump($path);
php 5.4 also has this new shorter ternary format which you can use if you don't care about notices (I do)
$path = $_SERVER['PATH_INFO']?:'/';
Handling the QUERY_STRING
Now tecnically you are not getting a URL, it is merely its path part and will not contain the query_string, for example when visiting
http://web.com/mysubfolder/index.php/test?param=val
you will only get '/test' in the $path variable, to get the query string use the $_SERVER['QUERY_STRING'] variable
index.php
function ifsetor(&$variable, $default = null) {
return isset($variable)? $variable: $default;
}
$path = ifsetor($_SERVER['PATH_INFO'],'/');
$fullpath = ($_SERVER['QUERY_STRING'])? $path.'?'.$_SERVER['QUERY_STRING']:$path;
var_dump($fullpath);
But that might depend on your needs
$_SERVER['QUERY_STRING'] vs $_GET
Also keep in mind that the $_SERVER['QUERY_STRING'] variable is different from the $_GET and $_REQUEST variables because it keeps duplicate parameters from the query string, for example:
Visiting this page
http://web.com/mysubfolder/controller/action?foo=1&foo=2&foo=3
if going to give you a $_SERVER['QUERY_STRING'] that looks like
?foo=1&foo=2&foo=3
While the $_GET variable is going to be an array like this:
array(
'foo'=>'3'
);
If you don't have .htaccess
You can try using the SCRIPT_NAME to your advantage
list($url) = explode('?',$_SERVER['REQUEST_URI']);
list($basepath) = explode('index.php',$_SERVER['SCRIPT_NAME']);
$url = substr($url,strlen($basepath));
If you like to blow up stuff like me :)
Your case
Class Route
{
private $_htaccess = TRUE;
private $_suffix = ".jsp";
public function params()
{
$url='';
//nombre del directorio actual del script ejecutandose.
//basename(dirname($_SERVER['SCRIPT_FILENAME']));
if($this->_htaccess !== FALSE):
//no está funcionando bien si está en un subdirectorio web, por ej stynat.dyndns.org/subdir/
// muestra el "subdir" como primer parámetro
list($url) = explode('?',$_SERVER['REQUEST_URI']);
$basepath = dirname($_SERVER['SCRIPT_NAME']);
$basepath = ($basepath==='/')? $basepath: $basepath.'/';
$url = substr($url,strlen($basepath));
else:
if(isset($_SERVER['PATH_INFO'])):
$url = $_SERVER['PATH_INFO'];
$url = preg_replace('|^/|','',$url);
endif;
endif;
$url = explode('/',$url);
var_dump($url);
var_dump($_GET);
}
}
I hope this helps
P.S. Sorry for the late reply :(
At some point you will have to check the $_SERVER ['HTTP_HOST'] and a config var defined by the programmer/user wich indicates the subfolder(s) where the app is located, and remove the portion you are not interested in from the rest of the URL.
You can check this forum post on the codeigniter formus for some hints.
CodeIgniter uses another different way to route the controller/method internally.
You do the routing by the $_SERVER['PATH_INFO'] value. You use the urls like this: myapp.com/index.php/controller/method .
To avoid showing index.php on the uri you must rely on an Apache rewrite rule, but even with that I think that the CI one is a nice solution, once you have your index file location, you can avoid all the hassle of parsing the URL.
If I am understanding what you are after correctly, then one solution may be to carry on doing what you are doing, but also get the path of the main routing script (using realpath() for example).
If the last folder (or folder before that etc) matches the beginning URL item (or another section), you ignore it and go for the next one.
Just my 2 cents :-).
Within the application configuration script place a variable which will be set to the path the application runs at.
An alternative is to dynamically set that path.
Before the part
$url = explode('/',preg_replace('/^(\/)/','',$url));
strip the location (sub-folder) path out of the $url string using the predefined application path.
This is how i implemented loader.php
<?php
/*#author arun ak
auto load controller class and function from url*/
class loader
{
private $request;
private $className;
private $funcName;
function __construct($folder = array())
{
$parse_res = parse_url($this->createUrl());
if(!empty($folder) && trim($folder['path'],DIRECTORY_SEPARATOR)!='')
{
$temp_path = explode(DIRECTORY_SEPARATOR,trim($parse_res['path'],DIRECTORY_SEPARATOR));
$folder_path = explode(DIRECTORY_SEPARATOR,trim($folder['path'],DIRECTORY_SEPARATOR));
$temp_path = array_diff($temp_path,$folder_path);
if(empty($temp_path))
{
$temp_path = '';
}
}else
{
if(trim($parse_res['path'],DIRECTORY_SEPARATOR)!='')
{
$temp_path = explode(DIRECTORY_SEPARATOR,trim($parse_res['path'],DIRECTORY_SEPARATOR));
}
else
$temp_path ='';
}
if(is_array($temp_path))
{
if(count($temp_path) ==1)
{
array_push($temp_path,'index');
}
foreach($temp_path as $pathname)
{
$this->request .= $pathname.':';
}
}
else $this->request = 'index'.':'.'index';
}
private function createUrl()
{
$pageURL = (#$_SERVER["HTTPS"] == "on") ? "https://" : "http://";
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
return $pageURL;
}
public function autolLoad()
{
if($this->request)
{
$parsedPath = explode(':',rtrim($this->request,':'));
if(is_file(APPLICATION_PATH.DIRECTORY_SEPARATOR.'controllers'.DIRECTORY_SEPARATOR.$parsedPath[0].'_controller'.'.php'))
{
include_once(APPLICATION_PATH.DIRECTORY_SEPARATOR.'controllers'.DIRECTORY_SEPARATOR.$parsedPath[0].'_controller'.'.php');
if(class_exists($parsedPath[0].'_controller'))
{
$class = $parsedPath[0].'_controller';
$obj = new $class();
//$config = new config('localhost','Winkstore','nCdyQyEdqDbBFpay','mawinkcms');
//$connect = connectdb::getinstance();
//$connect->setConfig($config);
//$connection_obj = $connect->connect();
//$db = $connect->getconnection();//mysql link object
//$obj->setDb($db);
$method = $parsedPath[1];
if(method_exists ($obj ,$parsedPath[1] ))
{
$obj->$method();
}else die('class method '.$method.' not defined');
}else die('class '.$parsedPath[0]. ' has not been defined' );
} else die('controller not found plz define one b4 u proceed'.APPLICATION_PATH.DIRECTORY_SEPARATOR.'controllers'.DIRECTORY_SEPARATOR.$parsedPath[0].'.php');
}else{ die('oops request not set,i know tis is not the correct way to error :)'); }
}
}
Now in my index file
//include_once('config.php');
include_once('connectdb.php');
require_once('../../../includes/db_connect.php');
include_once('view.php');
include_once('abstractController.php');
include_once('controller.php');
include_once('loader.php');
$loader = new loader(array('path'=>DIRECTORY_SEPARATOR.'magsonwink'.DIRECTORY_SEPARATOR.'modules'.DIRECTORY_SEPARATOR.'admin'.DIRECTORY_SEPARATOR.'atom'.DIRECTORY_SEPARATOR));
$loader->autolLoad();
I haven't used the concept of modules.only controller action and view are rendered.
Are you sure you have your htaccess correctly?
I guess if you're placing your framework on subfolder, then you have to change your RewriteBase in htaccess file from / to /subfolder/. it would be something like this:
# on root
RewriteBase /
#on subfolder
RewriteBase /subfolder/
that's only thing I could wonder of that in your case ...
I don't use OOP, but could show you some snippets of how I do things to dynamically detect if I'm in a subdirectory. Too keep it short and to the point I'll only describe parts of it instead of posting all the code.
So I start out with a .htaccess that send every request to redirect.php in which I splice up the $_SERVER['REQUEST_URI'] variable. I use regex to decide what parts should be keys and what should be values (I do this by assigning anything beginning with 0-9 as a value, and anything beginning with a-z as key) and build the array $GET[].
I then check the path to redirect.php and compare that to my $GET array, to decide where the actual URL begins - or in your case, which key is the controller. Would look something like this for you:
$controller = keyname($GET, count(explode('/', dirname($_SERVER['SCRIPT_NAME']))));
And that's it, I have the first part of the URL. The keyname() function looks like this:
/*************************************
* get key name from array position
*************************************/
function keyname ($arr, $pos)
{
$pos--;
if ( ($pos < 0) || ( $pos >= count($arr) ) )
return ""; // set this any way you like
reset($arr);
for($i = 0;$i < $pos; $i++) next($arr);
return key($arr);
}
To get the links pointing right I use a function called fixpath() like this:
print 'link';
And this is how that function looks:
/*************************************
* relative to absolute path
*************************************/
function fixpath ($path)
{
$root = dirname($_SERVER['SCRIPT_NAME']);
if ($root == "\\" || $root == ".") {
$root = "";
}
$newpath = explode('/', $path);
$newpath[0] .= $root;
return implode('/', $newpath);
}
I hope that helps and can give you some inspiration.
Forget about "reinventing the wheel is wrong" claims. They don't have to use our wheels. I walked on the same road a while ago and i'm totally grateful what i get... i hope you will too
When it comes to the answer to your specific problem -which if faced too- there is a very easy solution. it's a new line in .htaccess at root folder...
Just add line below to your root .htaccess file ; (if your subfoler is "subfolder" )
RewriteRule subfolder/ - [L]
This will leave apart this folder from rewriting directives
By using this way you can install as many instances of your framework as you wish. But if you want this to be framework driven then you have to create/change .htaccess within your framework.
Create /myBaseDirectory/public directory and put your files there - like index.php.
This works because Apache sees this directory like base directory.
basically grab the url string after your first slash, and then explode it into an array (i use '/' as a delimiter).
then carefully array_shift off your elements and store them as variables
item 0: controller
item 1: the action / method in that controller
item 2 thru n: the remaining array is your params
I'm trying to setup a system to minimize complexity for people updating the site as I will not be the main person updating daily content AND also provide clean URLs.
Since I am unable to use a DB, all of the content resides in one of two base folders (/private/content OR /private/utilities). For normal daily updates, the utilities (contains the page wrapper - header, nav, footer, etc.) folder wouldn't need to be accessed. This minimizes the amount of visible code to the daily editor.
I've created an array ($allowedContent) that has the list of valid sections that are accessible. The code tests against that array to verify that the user is not attempting to access inappropriate content. With the code below, these requests would be successful. Everything else would fail.
www.example.com/
www.example.com/popup/*
www.example.com/test
www.example.com/hello
www.example.com/foobar
My question is:
Is there anything that sticks out as a problem with this approach?
.htaccess
RewriteEngine On
# Rules
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php
PHP
// parse the URL
$requestURI = explode('/', $_SERVER['REQUEST_URI']);
//print_r ($requestURI);
// a list of non-restricted dynamic content
$allowedContent = array("test", "hello", "foobar");
$allowAccess = false; // assume hackers :o
// determine the section
if (!$requestURI[1]) { // none defined - use root/home
$section = 'home';
$skin = true;
$allowAccess = true;
} elseif ($requestURI[1] == 'popup') { // popup - no skin
$section = $requestURI[2];
$skin = false;
$allowAccess = true;
} else {
if (in_array($requestURI[1], $allowedContent)) { // verify that the requested content is allowed / prevent someone from trying to hack the site
$section = $requestURI[1];
$skin = true;
$allowAccess = true;
} else { // this would be either a 404 or a user trying to access a restricted directory
echo "evil laugh"; // obviously, this would change to a 404 redirect
}
}
Added code where content is called
// call the relevant content pieces
if ($allowAccess == true) {
if ($skin == true ) {
// call wrapper part 1
include $_SERVER['DOCUMENT_ROOT'] . '/private/utilities/wrapperOpen.php';
// call aside
include $_SERVER['DOCUMENT_ROOT'] . '/private/utilities/header.php';
// call aside
include $_SERVER['DOCUMENT_ROOT'] . '/private/utilities/aside.php';
}
// call CONTENT (based on section)
include $_SERVER['DOCUMENT_ROOT'] . '/private/content/' . $section . '/index.php';
if ($skin == true ) {
// call branding
include $_SERVER['DOCUMENT_ROOT'] . '/private/utilities/branding.php';
// call footer
include $_SERVER['DOCUMENT_ROOT'] . '/private/utilities/footer.php';
// call wrapper part 2
include $_SERVER['DOCUMENT_ROOT'] . '/private/utilities/wrapperClose.php';
}
}
this would work.
you coyuld also look into using xml to store data, but you need to keep watch over system memory usage and loading time if the files get too large. sosplit them up where possible.
can’t you talk them into using a database? webhosting with database is cheap.
I know that you can add rules in htaccess, but I see that PHP frameworks don't do that and somehow you still have pretty URLs. How do they do that if the server is not aware of the URL rules?
I've been looking Yii's url manager class but I don't understand how it does it.
This is usually done by routing all requests to a single entry point (a file that executes different code based on the request) with a rule like:
# Redirect everything that doesn't match a directory or file to index.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* index.php [L]
This file then compares the request ($_SERVER["REQUEST_URI"]) against a list of routes - a mapping of a pattern matching the request to a controller action (in MVC applications) or another path of execution. Frameworks often include a route that can infer the controller and action from the request itself, as a backup route.
A small, simplified example:
<?php
// Define a couple of simple actions
class Home {
public function GET() { return 'Homepage'; }
}
class About {
public function GET() { return 'About page'; }
}
// Mapping of request pattern (URL) to action classes (above)
$routes = array(
'/' => 'Home',
'/about' => 'About'
);
// Match the request to a route (find the first matching URL in routes)
$request = '/' . trim($_SERVER['REQUEST_URI'], '/');
$route = null;
foreach ($routes as $pattern => $class) {
if ($pattern == $request) {
$route = $class;
break;
}
}
// If no route matched, or class for route not found (404)
if (is_null($route) || !class_exists($route)) {
header('HTTP/1.1 404 Not Found');
echo 'Page not found';
exit(1);
}
// If method not found in action class, send a 405 (e.g. Home::POST())
if (!method_exists($route, $_SERVER["REQUEST_METHOD"])) {
header('HTTP/1.1 405 Method not allowed');
echo 'Method not allowed';
exit(1);
}
// Otherwise, return the result of the action
$action = new $route;
$result = call_user_func(array($action, $_SERVER["REQUEST_METHOD"]));
echo $result;
Combined with the first configuration, this is a simple script that will allow you to use URLs like domain.com/about. Hope this helps you make sense of what's going on here.
