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);

use Elasticsearch\ClientBuilder;

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

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

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

$params = [

'id' => 'uH5JtIkBC78u-UjcI9s-',
'body' => [
'doc' => [
'address' => '美国'
]
]
];

// Update doc at /my_index/_doc/my_id
$response = $client->update($params);
// response print
array(8) {
["_index"]=>
