Installation and using elasticsearch php client on Windows Xampp - php

Question

I'm downloaded the elasticsearch-5.1.1.zip from the https://www.elastic.co/downloads/elasticsearch
Then download the Elastica A PHP client for elasticsearch via composer with this command
composer require ruflin/elastica:dev-master
Now i want to open and make a test. When i run this command
bin\elasticsearch.bat
i get this error: The syntax of the command is incorrect.
On the other side if i try to use Elastica A PHP client i get some errors like this:
Fatal error: Uncaught Elastica\Exception\Connection\HttpException:
Couldn't connect to host, Elasticsearch down? in

At the note said, you're missing JDK8 or later
