Aggregates and merges configuration, from a variety of formats. Supports caching for fast bootstrap in production environments.


The standalone ConfigAggregator can be used to merge PHP-based configuration files:

use Zend\ConfigAggregator\ConfigAggregator;
use Zend\ConfigAggregator\PhpFileProvider;

$aggregator = new ConfigAggregator([
    new PhpFileProvider('*.global.php'),


Using this provider, each file should return a PHP array:

// db.global.php
return [
    'db' => [
        'dsn' => 'mysql:...',

// cache.global.php
return [
    'cache_storage' => 'redis',
    'redis' => [ ... ],


array(3) {
  'db' =>
  array(1) {
    'dsn' =>
    string(9) "mysql:..."
  'cache_storage' =>
  string(5) "redis"
  'redis' =>
  array(0) {

Configuration is merged in the same order as it is passed, with later entries having precedence.

Together with zend-config, zend-config-aggregator can be also used to load configuration in different formats, including YAML, JSON, XML, or INI:

use Zend\ConfigAggregator\ConfigAggregator;
use Zend\ConfigAggregator\ZendConfigProvider;

$aggregator = new ConfigAggregator([
    new ZendConfigProvider('config/*.{json,yaml,php}'),
