Final Class Yiisoft\Config\Modifier\RecursiveMerge

Enable recursive merge for specified groups.

The modifier should be specified as

RecursiveMerge::groups('params', 'events')

For example:

• configuration in application composer.json:

"config-plugin": {
    "params": "params.php",
}

• application params.php contents:

return [
    'key' => [
       'a' => 1,
       'b' => 2,
    ],
];

• configuration in vendor package:

"config-plugin": {
    "params": "params.php",
}

• vendor package params.php contents:

return [
    'key' => [
       'c' => 3,
       'd' => 4,
    ],
];

• getting configuration:

$config = new Config(new ConfigPaths($configsDir), null, [
    RecursiveMerge::groups('params')
]);

$result = $config->get('params');

The result will be:

[
    'key' => [
       'c' => 3,
       'd' => 4,
       'a' => 1,
       'b' => 2,
    ],
]
