To help ease automated building of the client, all configurations can be provided in a setting hash instead of calling the individual methods directly. This functionality is exposed through the ClientBuilder::FromConfig() static method, which accepts an array of configurations and returns a fully built client.

Array keys correspond to the method name, e.g. retries key corresponds to setRetries() method.

$params = [
    'hosts' => [
        'localhost:9200'
    ],
    'retries' => 2,
    'handler' => ClientBuilder::singleHandler()
];
$client = ClientBuilder::fromConfig($params);

Unknown parameters will throw an exception, to help the user find potential problems. If this behavior is not desired (e.g. you are using the hash for other purposes, and may have keys unrelated to the Elasticsearch client), you can set $quiet = true in fromConfig() to silence the exceptions.

$params = [
    'hosts' => [
        'localhost:9200'
    ],
    'retries' => 2,
    'imNotReal' => 5
];

// Set $quiet to true to ignore the unknown `imNotReal` key
$client = ClientBuilder::fromConfig($params, true);
