How to override bundle resources in micro-kernel Symfony? - php

I've got micro-kernel Symfony project with custom catalog structure.
I used this: https://github.com/ikoene/symfony-micro
How can I override e.g. Twig Resources (Exception views)?
Cookbook says that I should create a directory called TwigBundle in my Resources directory.
I made \AppBundle\Resources\TwigBundle\views\Exception directory. Overriding view does not seem to work.

Thanks for using the microkernel setup. Here's how to override exception views.
1. Create a custom ExceptionController
First off, we're gonna create our own ExceptionController which extends the base ExceptionController. This will allow us to overwrite the template path.
<?php
namespace AppBundle\Controller\Exception;
use Symfony\Bundle\TwigBundle\Controller\ExceptionController as BaseExceptionController;
use Symfony\Component\HttpFoundation\Request;
class ExceptionController extends BaseExceptionController
{
/**
* #param Request $request
* #param string $format
* #param int $code
* #param bool $showException
*
* #return string
*/
protected function findTemplate(Request $request, $format, $code, $showException)
{
$name = $showException ? 'exception' : 'error';
if ($showException && 'html' == $format) {
$name = 'exception_full';
}
// For error pages, try to find a template for the specific HTTP status code and format
if (!$showException) {
$template = sprintf('AppBundle:Exception:%s%s.%s.twig', $name, $code, $format);
if ($this->templateExists($template)) {
return $template;
}
}
// try to find a template for the given format
$template = sprintf('#Twig/Exception/%s.%s.twig', $name, $format);
if ($this->templateExists($template)) {
return $template;
}
// default to a generic HTML exception
$request->setRequestFormat('html');
return sprintf('#Twig/Exception/%s.html.twig', $showException ? 'exception_full' : $name);
}
}
2. Create the error templates
Create templates for the different error codes:
error.html.twig
error403.html.twig
error404.html.twig
In this example, the exception templates would be placed in AppBundle/Resources/views/Exception/
3. Override the default ExceptionController
Now let's point to our new exception controller in the configuration.
twig:
exception_controller: app.exception_controller:showAction

I really like your solution, but I found another way how to do it without custom exception controller.
I realized that automatical additional check for overrided templates happens in directory Resources in the directory when you store your kernel class.
So, for structure in your repo it's:
/Resources/TwigBundle/views/Exception/
Finally I changed a little bit the directory structure to have a 'app' directory with kernel file inside. Just like in the default Symfony project.

Return JSON for exception with octoberCMS

I have some custom routes
Route::get('/files/', [
'as' => 'read',
'uses' => 'Myname\MyPlugin\Http\Controllers\FilesController#read'
]);
Somewhere in my class I have a function to validate a path
private function getPath()
{
$path = Input::get('path');
if (!$path)
{
throw new MyException('parameter is missing. path required', 400);
}
return base_path().'/'.$path;
}
I have set a custom error handler with a JSOM but it's the error handler of OctoberCMS that render the error in HTML format.
Do you know a way to replace default error handler of OctoberCMS by a custom one ?
Thanks
Just found the anwser in the documentation : https://octobercms.com/docs/services/error-log#exception-handling
October provide App:error to manage Exception in your plugin.
App::error(function(MyException $exception) {
//do what you want here
}
Don't forger to create a custom Exception for your plugin. If you use the generic Exception, you'll catch all the Exceptions.
I am posting an alternative solution here for a custom error handler because of this questions's visibility on Google.
I had problems using App:error due to this issue on Github: https://github.com/octobercms/october/issues/3416
Rather than using October's App::error for a custom error handling, try the following:
Create a custom error handler that inherit's from October's error handler. For example, create the following class in plugins/{AUTHOR}/{PLUGIN}/classes/CustomHandler.php (assuming you are developing a plugin for OctoberCMS). Override the render method of the handler.
<?php
namespace {AUTHOR}\{PLUGIN}\Classes; //<-- CHANGE ME OBVIOUSLY FOR YOUR PLUGIN
use October\Rain\Foundation\Exception\Handler;
use Illuminate\Support\Facades\Event;
use Illuminate\Support\Facades\Response;
use Exception;
use Illuminate\Database\Eloquent\ModelNotFoundException; // As an example exception you want to handle ...
/* Custom error handler which replaces the default error handler for OctoberCMS. */
class CustomHandler extends Handler
{
/**
* Render an exception into an HTTP response.
*
* #param \Illuminate\Http\Request $request
* #param \Exception $exception
* #return \Illuminate\Http\Response
*/
public function render($request, Exception $exception)
{
/* Custom JSON response for ModelNotFoundException exceptions. */
if($exception instanceof ModelNotFoundException){
return Response::json(['error' => 'A record was not found for the resource that was requested.'], 404);
}
/* The rest of this code is just the 'default' code from OctoberCMS' error handler. */
/* The only change is the code above this comment where I handle a specific exception in a unique way.*/
/* i.e. I decided to return JSON for the error rather than an HTML error page (in debug mode). */
if (!class_exists('Event')) {
return parent::render($request, $exception);
}
$statusCode = $this->getStatusCode($exception);
$response = $this->callCustomHandlers($exception);
if (!is_null($response)) {
return Response::make($response, $statusCode);
}
if ($event = Event::fire('exception.beforeRender', [$exception, $statusCode, $request], true)) {
return Response::make($event, $statusCode);
}
return parent::render($request, $exception);
}
}
Then, in your plugin registration file Plugin.php, add a boot method with the following code:
<?php namespace {AUTHOR}\{PLUGIN};
use System\Classes\PluginBase;
use {AUTHOR}\{PLUGIN}\Classes\CustomHandler; //<-- IMPORTANT
use Illuminate\Contracts\Debug\ExceptionHandler; //<-- IMPORTANT
class Plugin extends PluginBase
{
/**
* #var array Plugin dependencies
*/
public $require = [];
public function registerComponents()
{
}
public function registerSettings()
{
}
public function boot(){
/* Replace the default error handler of OctoberCMS to return JSON format responses instead. */
/* Also, this is used in order to control the responses for certain types of errors/exceptions. */
/* We are going about it this way because App::error (as mentioned in the documentation for OctoberCMS), */
/* was not returning the response properly presumably because of a bug. Argh... */
$this->app->bind(
ExceptionHandler::class,
CustomHandler::class
);
}
}
Since, the new CustomHandler.php was added to the classes directory, the new class should already be picked up. No need for composer dump-autoload -o or changes to the composer.json.
That is it. When the ModelNotFoundException occurs, the response given to the web browser will be JSON that you wrote (from the custom error handler we created).

Sonata Media Bundle - How to extend FormatThumbnail.php

The Sonata Media Bundle you have the thumbnail property on a provider in the config where you can specify either
sonata.media.thumbnail.format
sonata.media.thumbnail.liip_imagine
This all fine and the sonata.media.thumbnail.format one works fine for everything I want to achieve. My problem comes in with what happens within these files.
In the FormatThumbnail.php there is a function called generatePublicUrl where they generate the url of the media file and also the name of the formatted file. They use the media id within the name or url. If you have private files not everyone must be able to see this causes a problem with it is easy to manipulate the id to another id.
I know the public files that will be served will always stay public so if the url can be guessed the user will access the file. For this specific reason I want to try and replace that id with the unique reference that the bundle uses before they create the actual formatted files as this will not be as easy to just change.
I am aware that there are still risks of leaking out data.
I want to change this
public function generatePublicUrl(MediaProviderInterface $provider, MediaInterface $media, $format)
{
if ($format == 'reference') {
$path = $provider->getReferenceImage($media);
} else {
$path = sprintf('%s/thumb_%s_%s.%s', $provider->generatePath($media), $media->getId(), $format, $this->getExtension($media));
}
return $path;
}
to this
public function generatePublicUrl(MediaProviderInterface $provider, MediaInterface $media, $format)
{
if ($format == 'reference') {
$path = $provider->getReferenceImage($media);
} else {
$path = sprintf('%s/thumb_%s_%s.%s', $provider->generatePath($media), $media->getProviderReference(), $format, $this->getExtension($media));
}
return $path;
}
How do I override the file that the bundle just picks up the change?
I have followed the steps on Sonata's site on how to install and set up the bundle using the easy extends bundle. I have my own Application\Sonata\MediaBundle folder that is extending the original Sonata\MediaBundle.
For installation related information have a look through the documentation(https://sonata-project.org/bundles/media/master/doc/reference/installation.html)
However I tried to create my own Thumbnail folder and creating a new FormatThumbnail.php as follows
<?php
namespace Application\Sonata\MediaBundle\Thumbnail;
use Sonata\MediaBundle\Model\MediaInterface;
use Sonata\MediaBundle\Provider\MediaProviderInterface;
use Sonata\MediaBundle\Thumbnail\FormatThumbnail as BaseFormatThumbnail;
class FormatThumbnail extends BaseFormatThumbnail
{
/**
* Overriding this to replace the id with the reference
*
* {#inheritdoc}
*/
public function generatePublicUrl(MediaProviderInterface $provider, MediaInterface $media, $format)
{
if ($format == 'reference') {
$path = $provider->getReferenceImage($media);
} else {
$path = sprintf('%s/thumb_%s_%s.%s', $provider->generatePath($media), $media->getProviderReference(), $format, $this->getExtension($media));
}
return $path;
}
}
But the bundle still generates everything using the id instead of the reference. Is there a more specific way to achieve extending this file and overriding the function?
After looking at a few different bundles and after looking in code I found that they physically have a parameter which is set to use Sonata\MediaBundle\Thumbnail\FormatThumbnail.
The solution is to override the parameter in the config aswell.
#As top level classification in app/config/config.yml
parameters:
sonata.media.thumbnail.format: Application\Sonata\MediaBundle\Thumbnail\FormatThumbnail
This way the custom FormatThumbnail class is injected everywhere it will be used within the bundle.

Change Zend Framework 2 default template resolver behavior

I've just started looking into Zend framework 2 .One thing that I can’t seem to figure out is how to change the behavior of the framework when its deciding what view template to use when i’m not passing it in the viewmodel.
When looking for the answer myself I found the following, which states that Zend resolves view templates using the pathing below:
{normalized-module-name}/{normalized-controller-name}/{normalized-action-name}
(Source: http://zend-framework-community.634137.n4.nabble.com/Question-regarding-template-path-stack-tp4660952p4660959.html)
Now I’m looking to edit or remove the normalized-module-name segment. All the view files stay in my module/views folder. The reason I want to change this is because I’m using sub namespaces as my module name, resulting in the first segment of the namespace as the normalized module name (which is not specific enough for me).
To give you an example, the module Foo\Bar will result in an example view being rendered from:
/modules/Foo/Bar/view/foo/test/index.phtml.
I would like to change that default behavior to:
/modules/Foo/Bar/view/bar/test/index.phtml
Starting with zf 2.3 you can use extra config parameter view_manager['controller_map'] to enable different template name resolving.
Look at this PR for more info: https://github.com/zendframework/zf2/pull/5670
'view_manager' => array(
'controller_map' => array(
'Foo\Bar' => true,
),
);
Will result in controller FQCN starting with 'Foo\Bar' to be resolved following those rules:
strip \Controller\ namespace
strip trailing Controller in classname
inflect CamelCase to dash
replace namespace separator with slash
Eg: Foo\Bar\Controller\Baz\TestController -> foo/bar/baz/test/actionname
Update:
Starting with zend-mvc v3.0 this is default behavior
I had a similar problem and here's my solution.
Default template injector is attached to an event manager of the current controller with priority -90, and it resolves a template name only if a view model is not provided with one.
Knowing this, you can create your own template injector with a required logic and attach it to the event manager with the higher priority.
Please see the code below:
public function onBootstrap(EventInterface $event)
{
$eventManager = $event->getApplication()->getEventManager();
$eventManager->getSharedManager()
->attach(
'Zend\Stdlib\DispatchableInterface',
MvcEvent::EVENT_DISPATCH,
new TemplateInjector(),
-80 // you can put here any negative number higher -90
);
}
Your template injector which resolves template paths instead of the default one.
class TemplateInjector
{
public function __invoke(MvcEvent $event)
{
$model = $event->getResult();
if (!$model instanceof ViewModel)
{
return;
}
$controller = $event->getTarget();
if ($model->getTemplate())
{
return ;
}
if (!is_object($controller))
{
return;
}
$namespace = explode('\\', ltrim(get_class($controller), '\\'));
$controllerClass = array_pop($namespace);
array_pop($namespace); //taking out the folder with controllers
array_shift($namespace); //taking out the company namespace
$moduleName = implode('/', $namespace);
$controller = substr($controllerClass, 0, strlen($controllerClass) - strlen('Controller'));
$action = $event->getRouteMatch()->getParam('action');
$model->setTemplate(strtolower($moduleName.'/'.$controller.'/'.$action));
}
}
Here's the link from my blog where I wrote about it in more details: http://blog.igorvorobiov.com/2014/10/18/creating-a-custom-template-injector-to-deal-with-sub-namespaces-in-zend-framework-2/
Right template to ViewModel is injected in MVC event 'dispatch' (defined in ViewManager) by Zend\Mvc\View\Http\InjectTemplateListener with priority -90
You'll have to create custom InjectTemplateListener and register it with higher priority to same event.
But I'd recommend to set template in every action by hand, because of performance - see http://samminds.com/2012/11/zf2-performance-quicktipp-1-viewmodels/
template name resolving is a heavy process(on system resources), and all the articles about ZF2 performance says that you should provide the template name manually to increase performance.
so don't waste time finding a way to do something that you will end up doing manually :D
In order to improve Next Developer answer, I write the following code in TemplateInjector.php:
class TemplateInjector
{
public function __invoke(MvcEvent $event)
{
$model = $event->getResult();
if (!$model instanceof ViewModel) {
return;
}
if ($model->getTemplate()) {
return;
}
$controller = $event->getTarget();
if (!is_object($controller)) {
return;
}
$splitNamespace = preg_split('/[\\\]+/', ltrim(get_class($controller), '\\'));
$moduleName = $splitNamespace[1];
$controller = $splitNamespace[0];
$action = $event->getRouteMatch()->getParam('action');
$model->setTemplate(strtolower($moduleName . '/' . $controller . '/' . $action));
}
}
I've changed the way to build the Template path. Using regexp is faster than using array methods.

Is there any way to compile a blade template from a string?

How can I compile a blade template from a string rather than a view file, like the code below:
<?php
$string = '<h2>{{ $name }}</h2>';
echo Blade::compile($string, array('name' => 'John Doe'));
?>
http://paste.laravel.com/ujL
I found the solution by extending BladeCompiler.
<?php namespace Laravel\Enhanced;
use Illuminate\View\Compilers\BladeCompiler as LaravelBladeCompiler;
class BladeCompiler extends LaravelBladeCompiler {
/**
* Compile blade template with passing arguments.
*
* #param string $value HTML-code including blade
* #param array $args Array of values used in blade
* #return string
*/
public function compileWiths($value, array $args = array())
{
$generated = parent::compileString($value);
ob_start() and extract($args, EXTR_SKIP);
// We'll include the view contents for parsing within a catcher
// so we can avoid any WSOD errors. If an exception occurs we
// will throw it out to the exception handler.
try
{
eval('?>'.$generated);
}
// If we caught an exception, we'll silently flush the output
// buffer so that no partially rendered views get thrown out
// to the client and confuse the user with junk.
catch (\Exception $e)
{
ob_get_clean(); throw $e;
}
$content = ob_get_clean();
return $content;
}
}
Small modification to the above script.
You can use this function inside any class without extending the BladeCompiler class.
public function bladeCompile($value, array $args = array())
{
$generated = \Blade::compileString($value);
ob_start() and extract($args, EXTR_SKIP);
// We'll include the view contents for parsing within a catcher
// so we can avoid any WSOD errors. If an exception occurs we
// will throw it out to the exception handler.
try
{
eval('?>'.$generated);
}
// If we caught an exception, we'll silently flush the output
// buffer so that no partially rendered views get thrown out
// to the client and confuse the user with junk.
catch (\Exception $e)
{
ob_get_clean(); throw $e;
}
$content = ob_get_clean();
return $content;
}
For anyone still interested in this, they've added it to Laravel 9
use Illuminate\Support\Facades\Blade;
return Blade::render('Hello, {{ $name }}', ['name' => 'Julian Bashir']);
https://laravel.com/docs/9.x/blade#rendering-inline-blade-templates
I just stumbled upon the same requirement! For me, i had to fetch a blade template stored in DB & render it to send email notifications.
I did this in laravel 5.8 by kind-of Extending \Illuminate\View\View. So, basically i created the below class & named him StringBlade (I couldn't find a better name atm :/)
<?php
namespace App\Central\Libraries\Blade;
use Illuminate\Filesystem\Filesystem;
class StringBlade implements StringBladeContract
{
/**
* #var Filesystem
*/
protected $file;
/**
* #var \Illuminate\View\View|\Illuminate\Contracts\View\Factory
*/
protected $viewer;
/**
* StringBlade constructor.
*
* #param Filesystem $file
*/
public function __construct(Filesystem $file)
{
$this->file = $file;
$this->viewer = view();
}
/**
* Get Blade File path.
*
* #param $bladeString
* #return bool|string
*/
protected function getBlade($bladeString)
{
$bladePath = $this->generateBladePath();
$content = \Blade::compileString($bladeString);
return $this->file->put($bladePath, $content)
? $bladePath
: false;
}
/**
* Get the rendered HTML.
*
* #param $bladeString
* #param array $data
* #return bool|string
*/
public function render($bladeString, $data = [])
{
// Put the php version of blade String to *.php temp file & returns the temp file path
$bladePath = $this->getBlade($bladeString);
if (!$bladePath) {
return false;
}
// Render the php temp file & return the HTML content
$content = $this->viewer->file($bladePath, $data)->render();
// Delete the php temp file.
$this->file->delete($bladePath);
return $content;
}
/**
* Generate a blade file path.
*
* #return string
*/
protected function generateBladePath()
{
$cachePath = rtrim(config('cache.stores.file.path'), '/');
$tempFileName = sha1('string-blade' . microtime());
$directory = "{$cachePath}/string-blades";
if (!is_dir($directory)) {
mkdir($directory, 0777);
}
return "{$directory}/{$tempFileName}.php";
}
}
As you can already see from the above, below are the steps followed:
First converted the blade string to the php equivalent using \Blade::compileString($bladeString).
Now we have to store it to a physical file. For this storage, the frameworks cache directory is used - storage/framework/cache/data/string-blades/
Now we can ask \Illuminate\View\Factory native method 'file()' to compile & render this file.
Delete the temp file immediately (In my case i didn't need to keep the php equivalent file, Probably same for you too)
And Finally i created a facade in a composer auto-loaded file for easy usage like below:
<?php
if (! function_exists('string_blade')) {
/**
* Get StringBlade Instance or returns the HTML after rendering the blade string with the given data.
*
* #param string $html
* #param array $data
* #return StringBladeContract|bool|string
*/
function string_blade(string $html, $data = [])
{
return !empty($html)
? app(StringBladeContract::class)->render($html, $data)
: app(StringBladeContract::class);
}
}
Now i can call it from anywhere like below:
<?php
$html = string_blade('<span>My Name is {{ $name }}</span>', ['name' => 'Nikhil']);
// Outputs HTML
// <span>My Name is Nikhil</span>
Hope this helps someone or at-least maybe inspires someone to re-write in a better way.
Cheers!
I'm not using blade this way but I thought that the compile method accepts only a view as argument.
Maybe you're looking for:
Blade::compileString()
It's a old question. But I found a package which makes the job easier.
Laravel Blade String Compiler renders the blade templates from the string value. Check the documentation on how to install the package.
Here is an example:
$template = '<h1>{{ $name }}</h1>'; // string blade template
return view (['template' => $template], ['name' => 'John Doe']);
Note: The package is now updated to support till Laravel 6.
I know its pretty old thread, but today also requirement is same.
Following is the way I solved this on my Laravel 5.7 (but this will work with any laravel version greater than version 5), I used the knowledge gained from this thread and few other threads to get this working (will leave links to all threads at the end, if this help up-vote those too)
I added this to my helper.php (I used this technique to add helper to my project, but you can use this function directly as well)
if (! function_exists('inline_view')) {
/**
* Get the evaluated view contents for the given blade string.
*
* #param string $view
* #param array $data
* #param array $mergeData
* #return \Illuminate\View\View|\Illuminate\Contracts\View\Factory
*/
function inline_view($view = null, $data = [], $mergeData = [])
{
/* Create a file with name as hash of the passed string */
$filename = hash('sha1', $view);
/* Putting it in storage/framework/views so that these files get cleared on `php artisan view:clear*/
$file_location = storage_path('framework/views/');
$filepath = storage_path('framework/views/'.$filename.'.blade.php');
/* Create file only if it doesn't exist */
if (!file_exists($filepath)) {
file_put_contents($filepath, $view);
}
/* Add storage/framework/views as a location from where view files can be picked, used in make function below */
view()->addLocation($file_location);
/* call the usual view helper to render the blade file created above */
return view($filename, $data, $mergeData);
}
}
Usage is exactly same as laravel's view() helper, only that now first parameter is the blade string
$view_string = '#if(strlen($name_html)>6)
<strong>{{ $name_html }}</strong>
#else
{{$name_html}}
#endif';
return inline_view($view_string)->with('name_html', $user->name);
return inline_view($view_string, ['name_html' => $user->name]);

Kohana 3.2. - How can I use hyphens in URIs

Recently I've been doing some research into SEO and how URIs that use hyphens or underscores are treated differently, particularly by Google who view hyphens as separators.
Anyway, eager to adapt my current project to meet this criteria I found that because Kohana uses function names to define pages I was receiving the unexpected '-' warning.
I was wondering whether there was any way to enable the use of URIs in Kohana like:
http://www.mysite.com/controller/function-name
Obviously I could setup a routeHandler for this... but if I was to have user generated content, i.e. news. I'd then have to get all articles from the database, produce the URI, and then do the routing for each one.
Are there any alternative solutions?
Note: This is the same approach as in Laurent's answer, just slightly more OOP-wise. Kohana allows one to very easily overload any system class, so we can use it to save us some typing and also to allow for cleaner updates in the future.
We can plug-in into the request flow in Kohana and fix the dashes in the action part of the URL. To do it we will override Request_Client_Internal system class and it's execute_request() method. There we'll check if request->action has dashes, and if so we'll switch them to underscores to allow php to call our method properly.
Step 1. Open your application/bootstrap.php and add this line:
define('URL_WITH_DASHES_ONLY', TRUE);
You use this constant to quickly disable this feature on some requests, if you need underscores in the url.
Step 2. Create a new php file in: application/classes/request/client/internal.php and paste this code:
<?php defined('SYSPATH') or die('No direct script access.');
class Request_Client_Internal extends Kohana_Request_Client_Internal {
/**
* We override this method to allow for dashes in the action part of the url
* (See Kohana_Request_Client_Internal::execute_request() for the details)
*
* #param Request $request
* #return Response
*/
public function execute_request(Request $request)
{
// Check the setting for dashes (the one set in bootstrap.php)
if (defined('URL_WITH_DASHES_ONLY') and URL_WITH_DASHES_ONLY == TRUE)
{
// Block URLs with underscore in the action to avoid duplicated content
if (strpos($request->action(), '_') !== false)
{
throw new HTTP_Exception_404('The requested URL :uri was not found on this server.', array(':uri' => $request->uri()));
}
// Modify action part of the request: transform all dashes to underscores
$request->action( strtr($request->action(), '-', '_') );
}
// We are done, let the parent method do the heavy lifting
return parent::execute_request($request);
}
} // end_class Request_Client_Internal
What this does is simply replacing all the dashes in the $request->action with underscores, thus if url was /something/foo-bar, Kohana will now happily route it to our action_foo_bar() method.
In the same time we block all the actions with underscores, to avoid the duplicated content problems.
No way to directly map a hyphenated string to a PHP function so you will have to do routing.
As far as user generated content, you could do something like Stack Exchange does. Each time user content is saved to the database, generated a slug for it (kohana-3-2-how-can-i-use-hyphens-in-uris) and save it along with the other information. Then when you need to link to it, use the unique id and append the slug to the end (ex:http://stackoverflow.com/questions/7404646/kohana-3-2-how-can-i-use-hyphens-in-uris) for readability.
You can do this with lambda functions: http://forum.kohanaframework.org/discussion/comment/62581#Comment_62581
You could do something like
Route::set('route', '<controller>/<identifier>', array(
'identifier' => '[a-zA-Z\-]*'
))
->defaults(array(
'controller' => 'Controller',
'action' => 'show',
));
Then receive your content identifier in the function with Request::current()->param('identifier') and parse it manually to find the relating data.
After having tried various solutions, I found that the easiest and most reliable way is to override Kohana_Request_Client_Internal::execute_request. To do so, add a file in your application folder in "application\classes\kohana\request\client\internal.php" then set its content to:
<?php defined('SYSPATH') or die('No direct script access.');
class Kohana_Request_Client_Internal extends Request_Client {
/**
* #var array
*/
protected $_previous_environment;
/**
* Processes the request, executing the controller action that handles this
* request, determined by the [Route].
*
* 1. Before the controller action is called, the [Controller::before] method
* will be called.
* 2. Next the controller action will be called.
* 3. After the controller action is called, the [Controller::after] method
* will be called.
*
* By default, the output from the controller is captured and returned, and

Then to add an action with hyphens, for example, "controller/my-action", create an action called "my_action()".
This method will also throw an error if the user tries to access "controller/my_action" (to avoid duplicate content).
I know some developers don't like this method but the advantage of it is that it doesn't rename the action, so if you check the current action it will be consistently called "my-action" everywhere. With the Route or lambda function method, the action will sometime be called "my_action", sometime "my-action" (since both methods rename the action).
