I have an Elasticsearch-PHP application and it works locally. However, when I put it on an RHEL 6 server that only supports PHP 5.3, it does not work. When I go to the console, I get GET [http://xx.x.xxx.xxx](http://xx.x.xxx.xxx):xxxx/init.php 500 (Internal Server Error). The problem I think might be from a connection issue in the init.php. Here's the code inside init.php:

```
<?php
require_once 'vendor/autoload.php';
use Elasticsearch\ClientBuilder;

/*Build connection*/
$hosts = [
'xx.x.xxx.xxx', // Port
];

$es = ClientBuilder::create() // Instantiate a new ClientBuilder
        ->setHosts($hosts) // Set the hosts
        ->build(); // Build the client object

?>

```

This works perfect locally. I don't know why it doesn't work when I transfer it to the server.
