Config

The Config library provides a simple interface for adding configuration values. All config files are loaded lazily only when invoked providing a clean yet efficient way of managing config.

Installation

Install with composer at krak/config

Usage

All Config is managed via the ConfigStore. Config\store provides a default instance which will lazy load files/data and will cache the results to prevent multiple filesystem calls.

Adding Config Items

Adding multiple entries under the same key will merge the data when it's retrieved. The entries added last will overwrite the previous entries.

<?php

$config = Krak\Config\store();
// add array data
$config->add('a', [
    'from_array' => true,
    'b' => ['c' => 1]
]);
$config->add('a', function() {
    return ['from_closure' => true],
});
// You can add, php, ini, json, or yml files, but you must provide the full path
$config->add('a', __DIR__ . '/path/a.php');

// or you can use this helper for files
$config->addFiles(__DIR__ . '/path', [
    'a.php',
]);
$config->addPhpFiles(__DIR__ . '/path', ['a']); // this is the exact same as above

PHP configuration files must return an array like so:

<?php

return [
    'from_php_file' => true
];

Note: For YAML files, you must install the Symfony YAML Component (symfony/yaml).

Getting Config Items

<?php

var_dump($config->get('a'));

// or retrieve nested items
$config->get('a.b.c');

This will display something like:

array(4) {
  ["from_array"]=>
  bool(true)
  ["from_closure"]=>
  bool(true)
  ["from_php_file"]=>
  bool(true)
}
