1、安装

通过composer安装
composer require 'elasticsearch/elasticsearch'

2、创建ES类

<?php
require 'vendor/autoload.php';
//如果未设置密码
$es = \Elasticsearch\ClientBuilder::create()->setHosts(['xxx.xxx.xxx.xxx'])->build();
//如果es设置了密码
$es = \Elasticsearch\ClientBuilder::create()->setHosts(['http://username:password@xxx.xxx.xxx.xxx:9200'])->build()

3、新建ES数据库

index 对应关系型数据（以下简称MySQL）里面的数据库，而不是对应MySQL里面的索引
<?php
$params = [
    'index' => 'autofelix_db', #index的名字不能是大写和下划线开头
    'body' => [
        'settings' => [
            'number_of_shards' => 5,
            'number_of_replicas' => 0
        ]
    ]
];
$es->indices()->create($params);

4、创建表

<?php
$params = [
    'index' => 'autofelix_db',
    'type' => 'autofelix_table',
    'body' => [
        'mytype' => [
            '_source' => [
                'enabled' => true
            ],
            'properties' => [
                'id' => [
                    'type' => 'integer'
                ],
                'first_name' => [
                    'type' => 'text',
                    'analyzer' => 'ik_max_word'
                ],
                'last_name' => [
                    'type' => 'text',
                    'analyzer' => 'ik_max_word'
                ],
                'age' => [
                    'type' => 'integer'
                ]
            ]
        ]
    ]
];
$es->indices()->putMapping($params);

5、插入数据

<?php
$params = [
    'index' => 'autofelix_db',
    'type' => 'autofelix_table',
    //'id' => 1, #可以手动指定id，也可以不指定随机生成
    'body' => [
        'first_name' => '测试1',
        'last_name' => '测试2',
        'age' => 30
    ]
];
$es->index($params);

6、查询所有数据

<?php
$data = $es->search();
var_dump($data);

7、查询单条数据

<?php
$params = [
    'index' => 'autofelix_db',
    'type' => 'autofelix_table',
    'id' =>  //你插入数据时候的id
];
$data = $es->get($params);

8、搜索

<?php
$params = [
    'index' => 'autofelix_db',
    'type' => 'autofelix_table',
    'body' => [
        'query' => [
            'constant_score' => [ //非评分模式执行
                'filter' => [ //过滤器，不会计算相关度，速度快
                    'term' => [ //精确查找，不支持多个条件
                        'first_name' => '测试1'
                    ]
                ]
            ]
        ]
    ]
];
$data = $es->search($params);
var_dump($data);
