or $params = array('hosts' => array('host'=>'127.0.0.1','port'=>8080));
and some other way
error have some info :
foreach ($params as $key => $value) {
if (array_search($key, $whitelist) === false) {
throw new UnexpectedValueException($key . ' is not a valid parameter');
}
}

Answer 1

The hosts array is not supposed to be keyed itself - that's basically what the error message is saying: key host (and port) is not expected.
In your code, try without the host key, just like this:
$params = array('hosts' => array('localhost:8080'));
The default is localhost:9200. For further details, read the official documentation.

Answer 2

Like matpop said, the "hosts"-array is not keyed itself. Here a example from the es-documentation.
$params = array();
$params['hosts'] = array (
'192.168.1.1:9200', // IP + Port
'192.168.1.2', // Just IP
'mydomain.server.com:9201', // Domain + Port
'mydomain2.server.com', // Just Domain
'https://localhost', // SSL to localhost
'https://192.168.1.3:9200' // SSL to IP + Port );
$client = new Elasticsearch\Client($params);
