开始

本页将指导您完成 PHP 客户端的安装过程，向您展示如何实例化客户端，以及如何使用它执行基本的 Elasticsearch 操作。

安装

composer require elasticsearch/elasticsearch

实例化客户端

require 'vendor/autoload.php';

$client = Elastic\Elasticsearch\ClientBuilder::create()->build();

创建索引

use Elasticsearch\ClientBuilder;

include "../vendor/autoload.php";

$hosts = [
    "http://192.168.33.10:9200"
];

$client = ClientBuilder::create()->setHosts($hosts)->build();
$params = [
    'index' => 'my_index',
];

$response = $client->indices()->create($params);

// response print
array(3) {
  ["acknowledged"]=>
  bool(true)
  ["shards_acknowledged"]=>
  bool(true)
  ["index"]=>
  string(8) "my_index"
}

插入一条数据

use Elasticsearch\ClientBuilder;

include "../vendor/autoload.php";

$hosts = [
    "http://192.168.33.10:9200"
];

$client = ClientBuilder::create()->setHosts($hosts)->build();

$response = $client->index([
    'index' => 'my_index',
    'body' => [
        'name' => 'Taylor',
        'age' => 32,
        'address' => "1101 S Main St APT 203 Milpitas CA 95035",
        'sex' => '女',
        'hobby' => ["唱歌", "跳舞", "谈恋爱", "走秀"]
    ]
]);
// response print
array(8) {
  ["_index"]=>
  string(8) "my_index"
  ["_type"]=>
  string(4) "_doc"
  ["_id"]=>
  string(20) "uH5JtIkBC78u-UjcI9s-"
  ["_version"]=>
  int(1)
  ["result"]=>
  string(7) "created"
  ["_shards"]=>
  array(3) {
    ["total"]=>
    int(2)
    ["successful"]=>
    int(1)
    ["failed"]=>
    int(0)
  }
  ["_seq_no"]=>
  int(0)
  ["_primary_term"]=>
  int(1)
}

插入多条

use Elasticsearch\ClientBuilder;

include "../vendor/autoload.php";

$hosts = [
    "http://192.168.33.10:9200"
];

$client = ClientBuilder::create()->setHosts($hosts)->build();

$params = ['body' => []];
for ($i = 1; $i < 6;$i++) {
    $params['body'][] = [
        'index' =>  [
            '_index' => 'my_index',
            '_id' => $i
        ]
    ];
    $params['body'][] = [
        'name' => "Swift".$i,
        'age' => rand(10, 35),
        'address' => "1101 S Main St APT 203 Milpitas CA 95035",
        'sex' => "女",
        'hobby' => ["唱歌", "跳舞", "谈恋爱", "走秀"]
    ];
}

$response = $client->bulk($params);
// response print 新增5条数据
