Hi friends,  
already 3 days I am fighting with tutorials for Elasticsearch, how to install it, how to use it with php etc.

Currently I have elasticsearch on server (debian 8) hopefully working, but I can't work with php.

I use just small part of code:

require 'vendor/autoload.php';

$client = Elasticsearch\ClientBuilder::create()-\>build();

$params = [  
'index' =\> 'my\_index',  
'type' =\> 'my\_type',  
'id' =\> 'my\_id',  
'body' =\> ['testField' =\> 'abc']  
];

$response = $client-\>index($params);  
print\_r($response);

And I get:

Notice: Use of undefined constant JSON\_PRESERVE\_ZERO\_FRACTION - assumed 'JSON\_PRESERVE\_ZERO\_FRACTION' in /var/www/nnc/vendor/elasticsearch/elasticsearch/src/Elasticsearch/Serializers/SmartSerializer.php on line 30

Warning: json\_encode() expects parameter 2 to be long, string given in /var/www/nnc/vendor/elasticsearch/elasticsearch/src/Elasticsearch/Serializers/SmartSerializer.php on line 30

I am running on debian 8 Jessie, php 5.6.27 (newest in repository).

Are you able to help me what's the trouble?

Same here, I had to revert to 3.3.0

```
$ php -v
PHP 5.6.29-0+deb8u1 (cli) (built: Dec 13 2016 16:02:08) 
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies

```

Is JSON\_PRESERVE\_ZERO\_FRACTION missing from this PHP package?
