安装

通过composer来下载Elasticsearch-php

composer require elasticsearch/elasticsearch

连接

在进行以下的文档操作前都要先通过下面的代码与ES建立连接

require_once 'vendor/autoload.php';

$hosts = [
    'http://localhost:9200',
];
$client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build();

文档新增

$params = [
    'index' => 'blogs',
    'id' => 4,
    'body' => [
        'doc' => [
            'content' => '删除测试'
        ]
    ]
];
$response = $client->create($params);
print_r($response);

文档修改

$params = [
    'index' => 'blogs',
    'id' => 1,
    'body' => [
        'doc' => [
            'content' => 'elasticSearch-PHP 更新'
        ]
    ]
];
$response = $client->update($params);
print_r($response);

文档高亮搜索

$params = [
    'index' => 'blogs',
    'body' => [
        'query' => [
            'match' => [
                'content' => '新测试'
            ]
        ],
        'highlight' => [
            'fields' => [
                'content'=> new \stdClass(),
            ]
        ],
        "size":5, // 可以通过size指定最多返回的文档个数
    ]
];
$response = $client->search($params);
print_r($response);

文档删除

$param = [
    'index' => 'blogs',
    'id' => 4
];
$response = $client->delete($param);
print_r($response);
