Sending invalid Unicode via socket.io

Well you can try to, but it will end up almost probably in an disconnect which is caused by the browser.
As i have learned here.

Given you have a string which contains invalid unicode like:

This will trouble the browser and the socket connection.

If you prepare your json with PHP and json_encode the Unicode will be escaped to some strings like these:

\ud83d\ude31\ud83d\ude31\ud83d\ude04\ud83d\ude04\ud83d\udc9c\ud83d\udc9c\ud83d\udc4a

But on clientside it will still result in invalid Unicode.

Silex Starter Stubs

There are several preconfigured Silex Apps on github. They let you start your Silex project in no time, which is good.
This makes Silex an even more simple rabbithole into the symfony2 world.

I started one myself and had a close look on the others, so i thought i share this.
They all differ a bit so you must choose what fits your needs the best.

They all follow some kind of “best practise” structure, some more, some less.

[Symfony 2][Twig] – Enabling (native) Twig Extensions

Symfony 2 – Set Default Locale On Form Login #2

A small update/correction out of sequence:

A few weeks ago i described how to hook into the form login process in order to change the user session´s locale.

In the meantime a non backwards compatible code modification has been introduced that outdated this article. From now on (Symfony 2.0.4) the locale and default locale settings are maintained within the request object (and not as used to be in the session).

So, here is a little update – under reserve – because the locale setting´s logic will probably change again in the future.

Silex, Twig und HTML5 BoilerPlate

Alright, there is a bundle for H5BP for symfony2 and there is Assetic, you can probably use both with Silex and thats just fine.
But in case you want to keep your Silex project lean (since its micro) you can use Twig and H5BP only and build / deploy your app from the outside.

With a little tuning of the H5BP build, of course / unfortunatly. (Ok thats the caveat)

So i have a structure like so:
web/
(this is the webroot, here is js/css/images, all that asset stuff and the index, here we use the recommended H5BP stuff’n’structure)
views/
(this is outside of webroot and here are all of the *.twig)

[Symfony 2] AsseticBundle, Less CSS & YUI Compressor unter OSX installieren

Das AsseticBundle ist ein Wrapper um Assetic, ein geniales Tool, um statische Assets für Webprojekte zu verwalten. AsseticBundle ist extrem einfach zu verwenden, einfach die entsprechende Filter-Chain via yaml konfigurieren, um mehr muss man sich nicht kümmern. Natürlich allerdings müssen die zugrundeliegenden Abhängigkeiten im Vorfeld installiert sein. In unserem Falle benötigen wir den Yui-Compressor als jar-File und Less CSS. Less ist ein node.js Modul, was bedingt, dass wir zuvor node.js installieren müssen.

PHP odds! today: pass by reference traps

This is dangerous:

//example array
$array = array('a' => array(array(243,453,435,232)));

foreach ($array['a'] as &$value) {
         $value[3] = $newvalue;
}

This works, but now the $value var is in the array by reference which can lateron lead to:
Notice: Array to string conversion
EDIT:
see below in the comments for when…

This works better:

[Symfony 2] Security Bundle: Set User Locale on Form Login

[UPDATE]
A recent update to this article may be found here: https://nerdpress.org/symfony-2-set-default-locale-on-form-login-2/

Das Security Bundle ist ein wenig magisch. Da muss man eine HTML-Form definieren, der Rest wird irgendwie konfiguriert (Namen der Post-Parameter wie “_username”, “_password” etc., den Redirect zum Referrer, Remember-Me Funktion und so weiter, das alles wird von der Firewall intern geregelt. Man muss nur eine Login-Route definieren, einen Stub-Controller + Action-Callable (der aber nie ausgeführt wird, weil die Firefall sich davorhängt), fertig.

Das ist angenehm einfach, solange man keine Fragen stellt. Aber wie führe ich zusätzliche Aktionen direkt nach erfolgtem Login aus, ohne Einfuss auf den Code des Security Bundles zu haben?

[Symfony 2] Security Bundle – Benutzer mit username oder email anmelden.

Augenscheinlich unterstützt das Security-Module nur die Authentifizierung via Benutzername und Password. Wie man sich mit einem Benutzernamen ODER der E-Mail-Adresse und einem Password authentifiziert, ist ein wenig versteckt. So gehts:
