A strictly typed configuration component for PHP. Inspired by Apache Commons Configuration.
- PHP 8.1+
composer require selective/configYou can use the Configuration to read single values from a multidimensional
array by passing the path to one of the get{type}() and find{type}() methods.
Each get*() / find*() method takes a default value as second argument.
If the path cannot be found in the original array, the default is used as return value.
A get*() method returns only the declared return type.
If the default value is not given and the element cannot be found, an exception is thrown.
A find*() method returns only the declared return type or null.
No exception is thrown if the element cannot be found.
<?php
use Selective\Config\Configuration;
$config = new Configuration([
'key1' => [
'key2' => [
'key3' => 'value1',
]
]
]);
// Output: value1
echo $config->getString('key1.key2.key3');Add this dependency injection container definition:
use Selective\Config\Configuration;
// ...
return [
// Application settings
Configuration::class => function () {
return new Configuration(require __DIR__ . '/settings.php');
},
// ...
];The settings:
// Database settings
$settings['db'] = [
'driver' => 'mysql',
'host' => 'localhost',
'username' => 'root',
'database' => 'test',
'password' => '',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'flags' => [
PDO::ATTR_PERSISTENT => false,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
],
];The container definition:
use Selective\Config\Configuration;
use PDO;
return [
// ...
PDO::class => static function (ContainerInterface $container) {
$config = $container->get(Configuration::class);
$host = $config->getString('db.host');
$dbname = $config->getString('db.database');
$username = $config->getString('db.username');
$password = $config->getString('db.password');
$charset = $config->getString('db.charset');
$flags = $config->getArray('db.flags');
$dsn = "mysql:host=$host;dbname=$dbname;charset=$charset";
return new PDO($dsn, $username, $password, $flags);
},
// ...
];The settings:
$settings['module'] = [
'key1' => 'my-value',
];The consumer class:
<?php
namespace App\Domain\User\Service;
use Selective\Config\Configuration;
final class Foo
{
private $config;
public function __construct(Configuration $config)
{
$this->config = $config;
}
public function bar()
{
$myKey1 = $this->config->getString('module.key1');
// ...
