Question

I'm trying to use Elasticsearch via the PHP API in symfony . I have installed Elasticsearch via composer .

This is my code that is being called:

<?php

namespace AppBundle\ElasticsearchQuery;
use Elasticsearch\ClientBuilder;

class ElasticsearchQuery
{
private $Host = ['http://localhost:9200'];
private $client;
private $index = "homestead";

public function  __construct()
{
    $this->client = Elasticsearch\ClientBuilder::create()
        >setHosts($Host)->build();
}

public function execute($verb, $params)
{
    switch ($verb) {
    case "create":
        $response = $client->index($params);
        break;
    case "read":
        $response = $client->get($params);
        break;
    case "search":
        $response = $client->search($params);
        break;
    case "delete":
        $response = $client->delete($params);
        break;
    }
}
}

and the error I am getting:

Fatal error: Class 'AppBundle\\ElasticsearchQuery\\Elasticsearch\\ClientBuilder' not found

I don't want it to look for Elasticsearch in my AppBundle, I want it to look for it in the vendors. How do I do that?

edit: using use \\Elasticsearch\\ClientBuilder; or Elasticsearch\\ClientBuilder::create() makes no difference

Answer 1

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

This should be either

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

or (since you've already imported that class into your namespace)

$this->client = ClientBuilder::create()
