Try to customize the console script in Symfony2

Yesterday, Symfony Reloaded 2.0 Preview was released.
I have tried to use this by symfony-demo.

Symfony 2 is in marked contrast to symfony 1.x, for example, the amount of the directories in Root is only three: "web", "src" and "cart"! How simple!

I found "console" script in the cart directory. when I ran it with the "--shell" option in my console, "Symfony 2" message was displayed like below:

So I tried to customize this "Symfony 2" message to change another one.

Symfony 2 is written in PHP 5.3, so each class has "namespace". I copied the files to change from the Symfony 2 core directory and replaced the namespace below:
// namespace Symfony\Framework\WebBundle\Console; // original
namespace Bundle\CartBundle\Console; // new
 and replaced the use path in the console script, too:
//use Symfony\Framework\WebBundle\Console\Application; // original
use Bundle\CartBundle\Console\Application; // new
 I added an ASCII Art, which is the unofficial charactor of symfony that was born in the Japanese symfony comunity and twitter. Her name is "Symfo-Nyan", she is cute!

You can see the original in this page

OK, after adding the ASCII Art to the message, I ran the console again:

  I saw it is easy to customize Symfony 2 but if you are not used to using "namespace" with PHP, you should learn about it.

symfony session storage with using MongoDB

MongoDB is  an open source, scalable, high-performance, schema-free, document-oriented database written in the C++ programming language.((via: wikipedia))

symfony has the file session storage class, PDO session storage class but has no MongoDB session storage class.

So I wrote the symfony session storage class with using MongoDB.
You can use below.

As a matter of course I don't think MongoDB is the best solution for session storage but it's faster than MySQL session storage.


If you use sfMongoSessionStorage class, you configure the factories.yml.

     class: sfMongoSessionStorage
       host: localhost          #hostname
       port: 27017              #port number
       db_name: symfony         #DB name
       collection_name: session #collection name

bench mark results

This is the bench mark results on my local machine.
$ ab -n 5000 -c 100 http://localhost/index.php

MySQL   => Requests per second:    10.86 [#/sec] (mean)
MongoDB => Requests per second:    16.61 [#/sec] (mean)

Default => Requests per second:    17.58 [#/sec] (mean)
MongoDB session storage is much faster than MySQL one.
