Index a document

In elasticsearch-php, almost everything is configured by associative arrays. The REST endpoint, document and optional parameters - everything is an associative array.

To index a document, we need to specify four pieces of information: index, type, id and a document body. This is done by constructing an associative array of key:value pairs. The request body is itself an associative array with key:value pairs corresponding to the data in your document:

$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id',
    'body' => ['testField' => 'abc']
];

$response = $client->index($params);
print_r($response);

The response that you get back indicates the document was created in the index that you specified. The response is an associative array containing a decoded version of the JSON that Elasticsearch returns:

Array
(
    [_index] => my_index
    [_type] => my_type
    [_id] => my_id
    [_version] => 1
    [created] => 1
)
