README
Config is a file configuration loader that supports PHP, INI, XML, JSON, and YML files.
Installation
In terminal:
composer require matiasnamendola/slimpower-config
Or you can add use this as your composer.json:
{ "require": { "matiasnamendola/slimpower-config": "dev-master" } }
Requirements
Config requires PHP 5.3+, and suggests using the Symfony Yaml component.
Config is designed to be very simple and straightforward to use. All you can do with it is load, get, and set.
Loading files
The Config
object can be created via the factory method load()
, or
by direct instantiation:
<?php use SlimPower\Config\Config; // Load a single file $conf = Config::load('config.json'); $conf = new Config('config.json'); // Load values from multiple files $conf = new Config(array('config.json', 'config.xml')); // Load all supported files in a directory $conf = new Config(__DIR__ . '/config'); // Load values from optional files $conf = new Config(array('config.dist.json', '?config.json'));
Files are parsed and loaded depending on the file extension. Note that when loading multiple files, entries with duplicate keys will take on the value from the last loaded file.
When loading a directory, the path is glob
ed and files are loaded in by
name alphabetically.
Getting values
Getting values can be done in three ways. One, by using the get()
method:
// Get value using key $debug = $conf->get('debug'); // Get value using nested key $secret = $conf->get('security.secret'); // Get a value with a fallback $ttl = $conf->get('app.timeout', 3000);
The second method, is by using it like an array:
// Get value using a simple key $debug = $conf['debug']; // Get value using a nested key $secret = $conf['security.secret']; // Get nested value like you would from a nested array $secret = $conf['security']['secret'];
The third method, is by using the all()
method:
// Get all values $data = $conf->all();
Setting values
Although Config supports setting values via set()
or, via the
array syntax, any changes made this way are NOT reflected back to the
source files. By design, if you need to make changes to your
configuration files, you have to do it manually.
$conf = Config::load('config.json'); // Sample value from our config file assert($conf['secret'] == '123'); // Update config value to something else $conf['secret'] = '456'; // Reload the file $conf = Config::load('config.json'); // Same value as before assert($conf['secret'] == '123'); // This will fail assert($conf['secret'] == '456');
Using with default values
Sometimes in your own projects you may want to use Config for storing
application settings, without needing file I/O. You can do this by extending
the AbstractConfig
class and populating the getDefaults()
method:
<?php namespace ...; use SlimPower\Config\AbstractConfig; class MyConfig extends AbstractConfig { protected function getDefaults() { return array( 'host' => 'localhost', 'port' => 80, 'servers' => array( 'host1', 'host2', 'host3' ), 'application' => array( 'name' => 'configuration', 'secret' => 's3cr3t' ) ); } }
