php-elasticaHow do I use the Elastica library in PHP?

The Elastica library is a powerful tool for quickly and easily connecting to and managing Elasticsearch from PHP. It provides a simple and intuitive interface for creating, updating, and deleting documents, as well as running queries and aggregations.

To use the Elastica library in PHP, first install it with Composer:

composer require elastica/elastica

Then, create an instance of the Elastica\Client class, passing in an array of configuration parameters:

$config = [
    'host' => 'localhost',
    'port' => 9200,
];
$client = new \Elastica\Client($config);

Once the client is created, you can use it to interact with Elasticsearch. For example, to create an index:

$index = $client->getIndex('my_index');
$index->create(['settings' => ['number_of_shards' => 1]]);

Or, to index a document:

$doc = new \Elastica\Document(1, ['name' => 'John Doe']);
$index->addDocument($doc);

For more information on the Elastica library, please see the documentation.
