首先打开Elasticsearch官网了解对应编程语言的API https://www.elastic.co/guide/en/elasticsearch/client/index.htmlphp
点击 PHP API便可查看当前7.X版本的文档内容了html
咱们使用TP5来做为示例shell
首先须要安装操做Elasticsearch的PHP客户端库,咱们打开https://packagist.org/,搜索Elasticsearch。编程
这里有个Elasticsearch-PHP和Elasticsearch版本的对照表,咱们须要根据咱们本身使用的Elasticsearch的版本下载对应的Elasticsearch-PHPapi
因为个人Elasticsearch版本是7.6.2,因此这里咱们能够下载最新的Elasticsearch-PHP版本为7.8.0数组
咱们进入到本身的项目目录里安装Elasticsearch-PHPapp
composer require elasticsearch/elasticsearch=7.8.*
官方配置文档:https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/configuration.htmlcomposer
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); var_dump($client);
建立一个名为users的索引同时建立映射,并制定映射中各个字段的类型elasticsearch
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $params = [ 'index' => 'users', 'body' => [ 'settings' => [ 'number_of_shards' => 3, 'number_of_replicas' => 2 ], 'mappings' => [ '_source' => [ 'enabled' => true ], 'properties' => [ 'name' => [ 'type' => 'keyword' ], 'age' => [ 'type' => 'integer' ], 'mobile' => [ 'type' => 'text' ], 'email' => [ 'type' => 'text' ], 'birthday' => [ 'type' => 'date' ], 'address' => [ 'type' => 'text' ] ] ] ] ]; // Create the index with mappings and settings now $response = $client->indices()->create($params); dump($response);
当你要在 Elasticsearch 增长文档时,你就须要索引 JSON 文档。JSON 文档会映射 PHP 关联数组,由于 PHP 关联数组能够 encode 为 JSON 数据格式。编程语言
所以在 Elasticsearch-PHP 中你能够传递关联数组给客户端来索引文档。咱们会概述几种方法来增长文档到 Elasticsearch。
当索引一个文档时,你能够提供一个 ID 或者让 Elasticsearch 自动生成。
如今有以下数据,咱们将其添加到users索引中
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $params = [ 'index' => 'users', 'id' => 1, 'body' => [ 'name' => '张三', 'age' => 10, 'email' => 'zs@gmail.com', 'birthday' => '1990-12-12', 'address' => '北京' ] ]; $client->index($params);
经过Kibana能够查看到已经成功添加到Elasticsearch中
Elasticsearch 也支持批量(bulk)索引文档。bulk API 要求提供 JSON 格式的 action/元数据 键值对。在 PHP 中构建批量文档数据也是类似的。你首先要建立一个 action 数组对象(如 index
对象),而后你还要建立一个 body 对象。而 PHP 程序则重复上述操做构建文档数据。
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $arr = [ ['name' => '张三', 'age' => 10, 'email' => 'zs@gmail.com', 'birthday' => '1990-12-12', 'address' => '北京'], ['name' => '李四', 'age' => 20, 'email' => 'ls@gmail.com', 'birthday' => '1990-10-15', 'address' => '河南'], ['name' => '白兮', 'age' => 15, 'email' => 'bx@gmail.com', 'birthday' => '1970-08-12', 'address' => '杭州'], ['name' => '王五', 'age' => 25, 'email' => 'ww@gmail.com', 'birthday' => '1980-12-01', 'address' => '四川'], ]; foreach ($arr as $key => $document) { $params['body'][] = [ 'index' => [ '_index' => 'users', '_id' => $key ] ]; $params['body'][] = [ 'name' => $document['name'], 'age' => $document['age'], 'email' => $document['email'], 'birthday' => $document['birthday'], 'address' => $document['address'] ]; } if (isset($params) && !empty($params)) { $client->bulk($params); }
若是数据量很少能够用上面的方法,若是数据量不少的话,咱们就能够考虑分次添加
Elasticsearch 提供实时获取文档的方法。这意味着只要文档被索引且客户端收到消息确认后,你就能够当即在任何的分片中检索文档。Get 操做经过 index/type/id
方式请求一个文档信息:
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $params = [ 'index' => 'users', 'id' => 1 ]; $response = $client->get($params); dump($response);
若是你要部分更新文档(如更改现存字段,或添加新字段),你能够在 body 参数中指定一个 doc 参数。这样 doc 参数内的字段会与现存字段进行合并。
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $params = [ 'index' => 'users', 'id' => 1, 'body' => [ 'doc' => [ 'mobile' => '17612345678' ] ] ]; $response = $client->update($params); dump($response);
有时你要执行一个脚原本进行更新操做,如对字段进行自增操做或添加新字段。为了执行一个脚本更新,你要提供脚本命令和一些参数:
例如:将李四的年龄增长5岁
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $params = [ 'index' => 'users', 'id' => '1', 'body' => [ 'script' => 'ctx._source.age += 5', ] ]; $response = $client->update($params); dump($response);
经过Kibana查看发现年龄已经增长了5岁
经过指定文档的 /index/type/id
路径能够删除文档:
$hosts = [ '127.0.0.1:9200', //IP+端口 ]; $client = \Elasticsearch\ClientBuilder::create()->setHosts($hosts)->build(); $params = [ 'index' => 'users', 'id' => 2, ]; $response = $client->delete($params); dump($response);
