Using Elasticsearch in PHP

composer require elasticsearch/elasticsearch

will automatically load the appropriate version! My php is 5.6, it will automatically load the 5.3 elasticsearch version!

Using version ^5.3 for elasticsearch/elasticsearch ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 4 installs, 0 updates, 0 removals - Installing react/promise (v2.7.0): Downloading (100%) - Installing guzzlehttp/streams (3.0.0): Downloading (100%) - Installing guzzlehttp/ringphp (1.1.0): Downloading (100%) - Installing elasticsearch/elasticsearch (v5.3.2): Downloading (100%) Writing lock file Generating autoload files

Simple use

es = \Elasticsearch\ClientBuilder::create()->setHosts($params)->build(); } public function search() { $params = [ 'index' => 'megacorp', 'type' => 'employee', 'body' => [ 'query' => [ 'constant_score' => [ //非评分模式执行 'filter' => [ //过滤器，不会计算相关度，速度快 'term' => [ //精确查找，不支持多个条件 'about' => '谭' ] ] ] ] ] ]; $res = $this->es->search($params); print_r($res); } }

search();

Execution results

Array ( [took] => 2 [timed_out] => [_shards] => Array ( [total] => 5 [successful] => 5 [skipped] => 0 [failed] => 0 ) [hits] => Array ( [total] => 1 [max_score] => 1 [hits] => Array ( [0] => Array ( [_index] => megacorp [_type] => employee [_id] => 3 [_score] => 1 [_source] => Array ( [first_name] => 李 [last_name] => 四 [age] => 24 [about] => 一个PHP程序员，热爱编程，谭康很帅，充满激情。 [interests] => Array ( [0] => 英雄联盟 ) ) ) ) ) )

The following are some official examples:

Initialization

require '../vendor/autoload.php'; use Elasticsearch\ClientBuilder; $client = ClientBuilder::create()->build();

Add configuration

$hosts = [ '127.0.01:9200', // IP + Port ]; $client = ClientBuilder::create() // Instantiate a new ClientBuilder ->setHosts($hosts) // Set the hosts ->build(); // Build the client object

or

$hosts = [ '127.0.01:9200', // IP + Port ]; $clientBuilder = ClientBuilder::create(); // Instantiate a new ClientBuilder $clientBuilder->setHosts($hosts); // Set the hosts $client = $clientBuilder->build(); // Build the client object

Insert a document

// Index 一个文档 $params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id', 'body' => ['testField' => 'abc'] ]; $response = $client->index($params); print_r($response);

Get a document

$params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id' ]; $response = $client->get($params); print_r($response);

Query a document

$params = [ 'index' => 'my_index', 'type' => 'my_type', 'body' => [ 'query' => [ 'match' => [ 'testField' => 'abc' ] ] ] ]; $response = $client->search($params); print_r($response);

Delete a document

$params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id' ]; $response = $client->delete($params); print_r($response);

The results are as follows

Array ( [_index] => my_index [_type] => my_type [_id] => my_id [_version] => 3 [result] => deleted [_shards] => Array ( [total] => 2 [successful] => 1 [failed] => 0 ) [_seq_no] => 2 [_primary_term] => 1 )

Delete an index

$deleteParams = [ 'index' => 'my_index' ]; $response = $client->indices()->delete($deleteParams); print_r($response);

Create an index

$params = [ 'index' => 'my_index', 'body' => [ 'settings' => [ 'number_of_shards' => 2, 'number_of_replicas' => 0 ] ] ]; $response = $client->indices()->create($params); print_r($response);
