在哪里放置我需要的Symfony2自定义参数？

Question

I need to have some configuration for my bundle in Symfony2 Where is the best place to put them?
and how can I retrieve them from there?

I used my Default DB parameters in PARAMETERS.INI But I need Extra ones that I can retrieve them personally in code.

Answer 1

应该将他的参数保存在bundle中，例如src/Company/SomeBundle/Resources/config/parameters.yml

Answer 2

To define any extra parameters you need, define them in your config.yml file. Something like:

# app/config/config.yml
parameters:
    my_mailer.class:      Acme\HelloBundle\Mailer
    my_mailer.transport:  sendmail

Then you can retrieve them anywhere that the service container is available, for example inside a controller, just like you retrieve any other service like doctrine or swiftmailer. For example, in a controller, do

$transport = $this->get('my_mailer.transport');

If you want, you can define these parameters in paramters.ini, you will get the same result.

Answer 3

See the How to expose a Semantic Configuration for a Bundle cookbook entry. One of the advantages of this approach is that you can validate the configuration.

Answer 4

use different parts in parameters.ini file. You could have a prod1 environment using parameters prefixed with prod1 and a prod2 with the same:

parameters.ini:

[parameters]
prod1_database_driver = pdo_mysql
prod1_database_host = 127.0.0.1

# ...

prod2_database_driver = pdo_mysql
prod2_database_host = localhost

They both use the prod.yml configuration but overwrite the stuff you want to read from the parameters.ini:

config_prod1.yml:

imports:
 - { resource: config_prod.yml }

// .. overwrite stuff here
