这篇文章主要介绍了关于PHP中使用Elasticsearch的方法，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下PHP中使用Elasticsearch
composer require elasticsearch/elasticsearch
会自动加载合适的版本！我的php是5.6的，它会自动加载5.3的elasticsearch版本！

简单使用
<?phpclass MyElasticSearch{
private $es;
// 构造函数
public function __construct()
{
include('../vendor/autoload.php');
$params = array(
'127.0.0.1:9200'
);
$this->es = ElasticsearchClientBuilder::create()->setHosts($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($res);
}}<?phprequire "./MyElasticSearch.php";$es = new MyElasticSearch();$es->search();
执行结果
Array( [took] => 2 [timed_out] => [_shards] => Array ( [total] => 5 [successful] => 5 [skipped] => 0 [failed] => 0 ) [hits] => Array ( [total] => 1 [max_score] => 1 [hits] => Array ( [0] => Array ( [_index] => megacorp [_type] => employee [_id] => 3 [_score] => 1 [_source] => Array ( [first_name] => 李 [last_name] => 四 [age] => 24 [about] => 一个PHP程序员，热爱编程，谭康很帅，充满激情。 [interests] => Array ( [0] => 英雄联盟 ) ) ) ) ))
下面是官方的一些样例：
初始化
require '../vendor/autoload.php';use ElasticsearchClientBuilder;$client = ClientBuilder::create()->build();
增加配置
$hosts = [ '127.0.01:9200', // IP + Port];$client = ClientBuilder::create() // Instantiate a new ClientBuilder->setHosts($hosts) // Set the hosts->build(); // Build the client object
或
$hosts = [ '127.0.01:9200', // IP + Port];$clientBuilder = ClientBuilder::create(); // Instantiate a new ClientBuilder$clientBuilder->setHosts($hosts); // Set the hosts$client = $clientBuilder->build(); // Build the client object
插入一个文档
// Index 一个文档$params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id', 'body' => ['testField' => 'abc']];$response = $client->index($params);print_r($response);
获取一个文档
$params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id'];$response = $client->get($params);print_r($response);
查询一个文档
$params = [ 'index' => 'my_index', 'type' => 'my_type', 'body' => [ 'query' => [ 'match' => [ 'testField' => 'abc' ] ] ]];$response = $client->search($params);print_r($response);
删除一个文档
$params = [ 'index' => 'my_index', 'type' => 'my_type', 'id' => 'my_id'];$response = $client->delete($params);print_r($response);
结果如下
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)
删除一个索引
$deleteParams = [ 'index' => 'my_index'];$response = $client->indices()->delete($deleteParams);print_r($response);
创建一个索引
$params = [ 'index' => 'my_index', 'body' => [ 'settings' => [ 'number_of_shards' => 2, 'number_of_replicas' => 0 ] ]];$response = $client->indices()->create($params);print_r($response);
