ConfigExtension

Silex extension to read php .ini files used for configurations.

Installation

Add the following to composer.json.

"autoload" : {
    "psr-0" : {
        "ConfigExtension": "ConfigExtension/src/ConfigExtension/"
    }
}

This assumes the ConfigExtension folder is in the same directory as composer.json

Run: "composer dumpautoload"

Usage

Here is an example of its usage.

We have this .ini file:

[db]
options.driver  = "pdo_pgsql"
options.dbname  = "name"
options.host    = "localhost"
options.user    = "myuser"
options.password = "mysecretpass"
dbal.class_path = "%basepath%/vendor/doctrine/lib/vendor/doctrine-dbal/lib/"
common.class_path = "%basepath%/vendor/doctrine/lib/vendor/doctrine-common/lib/"
orm.class_path = "%basepath%/vendor/doctrine/lib/"

And the index.php:

<?php

require_once __DIR__ . '/../vendor/autoload.php';

$app = new Silex\Application();

$app->register(new \ConfigExtension\Extension\ConfigExtension(), array(
    // specify the .ini file to read
    'config.path' =>  __DIR__ . '/../config/app.ini',
    // and the var replacements
    'config.replacements' => array('basepath' => __DIR__ )
));

// retrieve just one value form teh config file
$db_name = $app['config']->get('db.name');

// adds all the specified section to the silex application
$app['config']->registerSection($app, 'db');

// $app['db.options.driver'] now has pdo_pgsql

$app->get('/', function () use ($app)
{
    return var_export($app['config']->getSection('db'), true);
});

$app->run();

Visiting '/' shows:

array (
  'db.options.driver' => 'pdo_pgsql',
  'db.options.dbname' => 'name',
  'db.options.host' => 'localhost',
  'db.options.user' => 'myuser',
  'db.options.password' => 'mysecredpass',
  'db.dbal.class_path' => '/Users/alinares/Sites/test/vendor/doctrine-dbal/lib/',
  'db.common.class_path' => '/Users/alinares/Sites/test/vendor/doctrine/lib/vendor/doctrine-common/lib/',
  'db.orm.class_path' => '/Users/alinares/Sites/test/vendor/doctrine/lib/',
)
