本文将为您详细介绍如何使用PHP操作Elasticsearch7.6。这篇文章非常实用，希望能为您提供有价值的参考，助您在学习后有所收获。

使用PHP操作Elasticsearch 7.6

Elasticsearch是一款开源、分布式的RESTful搜索和分析引擎。通过Elasticsearch PHP API（包括Elasticsearch和Elasticsearch 7），PHP可以与Elasticsearch进行交互。

安装Elasticsearch PHP API

立即学习“PHP免费学习笔记（深入）”；

通过Composer安装API：

composer require elasticsearch/elasticsearch

配置连接

$client = new Elasticsearch\Client([
    "hosts" => [
        "localhost:9200"
    ]
]);

登录后复制

创建索引

$client->indices()->create([
    "index" => "my_index"
]);

登录后复制

添加文档

$client->index([
    "index" => "my_index",
    "type" => "my_type",
    "id" => "1",
    "body" => [
        "name" => "John Doe",
        "age" => 30
    ]
]);

登录后复制

搜索文档

$query = [
    "query" => [
        "match" => [
            "name" => "John Doe"
        ]
    ]
];

$results = $client->search([
    "index" => "my_index",
    "type" => "my_type",
    "body" => $query
]);

登录后复制

更新文档

$query = [
    "script" => [
        "source" => "ctx._source.age  = 1"
    ]
];

$client->update([
    "index" => "my_index",
    "type" => "my_type",
    "id" => "1",
    "body" => $query
]);

登录后复制

删除文档

$client->delete([
    "index" => "my_index",
    "type" => "my_type",
    "id" => "1"
]);

登录后复制

聚合查询

$query = [
    "aggs" => [
        "age_group" => [
            "terms" => [
                "field" => "age",
                "size" => 10
            ]
        ]
    ]
];

$results = $client->search([
    "index" => "my_index",
    "type" => "my_type",
    "body" => $query
]);

登录后复制

实时索引

$client->indices()->putMapping([
    "index" => "my_index",
    "type" => "my_type",
    "body" => [
        "_doc" => [
            "_source" => [
                "enabled" => false
            ]
        ]
    ]
]);

登录后复制

连接到云服务提供商

Elasticsearch提供托管服务，如Amazon Elasticsearch Service (AES) 和 Azure Elasticsearch Service (AES)。使用PHP API可以连接到这些服务。

$client = new Elasticsearch\Client([
    "cloud" => [
        "id" => "your_cloud_id",
        "key" => "your_api_key"
    ]
]);

登录后复制

最佳实践

使用适当的数据类型
优化查询性能
利用缓存机制
监控系统性能
