2.elasticsearch-php

1.在国内下载网址下载elasticsearch
2.解压运行

bin\elasticsearch.bat

3.打开浏览器输入

http://localhost:9200/

4.创建composer.json

{
    "require": {
        "elasticsearch/elasticsearch": "~6.0"
    }
}

5.在composer.json文件的目录下运行

composer update elasticsearch/elasticsearch

6.创建index.php文件(名字随便起)

<?php
require 'vendor/autoload.php';
use Elasticsearch\ClientBuilder;

// 实例化一个客户端
$client = ClientBuilder::create()->build();

7.索引一个文档(创建一条数据)

// 索引一个文档(创建一条数据)
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id',
    'body' => ['testField' => 'abc']
];
$response = $client->index($params);
print_r($response);

打印结果

Array
(
    [_index] => my_index		//创建的index名
    [_type] => my_type		//创建的tupe名
    [_id] => my_id		//创建的id名
    [_version] => 1
    [result] => created
    [_shards] => Array
        (
            [total] => 2
            [successful] => 1
            [failed] => 0
        )

    [_seq_no] => 0
    [_primary_term] => 1
)

8.获取一个文档(查询一条记录)

$params = [
    'index' => 'my_index',

    'id' => 'my_id'
];
$response = $client->get($params);
print_r($response);

        (
            [testField] => abc		//刚才设置的内容
        )

)

9.搜索一个文档(搜索)

            'match' => [
                'testField' => 'abc'
            ]
        ]
    ]

            [successful] => 1
            [skipped] => 0
            [failed] => 0
        )

    [hits] => Array
        (
            [total] => Array
                (
                    [value] => 1
                    [relation] => eq
                )

            [max_score] => 0.2876821
            [hits] => Array
                (

                                )

                        )

                )

        )

10.删除一个文档(删除指定id)

// 删除一个文档(删除指定id)
$params = [
    'index' => 'my_index',

    'id' => 'my_id'
];

$response = $client->delete($params);
print_r($response);

打印结果

Array
(
    [_index] => my_index
    [_type] => my_type

            [failed] => 0
        )

    [_seq_no] => 1
    [_primary_term] => 1
)

11.删除一个索引

// 删除一个索引
// 创建第一个文档时会自动创建一个索引，同事将setting里面的参数设置为默认值
$deleteParams = [
    'index' => 'my_index'
];
$response = $client->indices()->delete($deleteParams);
print_r($response);

打印结果

Array
(
    [acknowledged] => 1
)

12.创建一个索引同时设置setting

// 创建一个索引 同事设置setting
$params = [
    'index' => 'my_index',
    'body' => [
        'settings' => [
            'number_of_shards' => 2,
            'number_of_replicas' => 0
        ]
    ]
];
$response = $client->indices()->create($params);
print_r($response);

打印结果

Array
(
    [acknowledged] => 1
    [shards_acknowledged] => 1
    [index] => my_index
)
