1、安装扩展

composer require elasticsearch/elasticsearch

2、连接ES客户端

<?php/*User : AdministratorDate : 2020/8/31Time : 14:36*/use Elasticsearch\ClientBuilder;class EsModel{protected function getEsClient(){$client = ClientBuilder::create()->setHosts([$this->getEsConfig()])->setConnectionPool('\Elasticsearch\ConnectionPool\SimpleConnectionPool', [])->setRetries(10)->build();return $client;}protected function getEsConfig(){$config = ['host'=> '127.0.0.1','port'=> '8200','scheme'=> 'http','user'=> 'root','pass'=> '123456'];return $config;}}

3、插入数据

public function insertDataIntoEs($tableName,array $data){$params = ['index' => $tableName,'id'=> $data['id'],'body'=> $data];$client = $this->getEsClient();$result = $client->index($params);return $result;}public function insertAllDataIntoEs(array $data) { $client = $this->getEsClient(); $result = $client->bulk($data); return $result; }

4、删除数据

public function deleteDataFromEsById($tableName,$id){$params = ['index' => $tableName,'id'=> $id];$client = $this->getEsClient();$result = $client->delete($params);return $result;}

5、基本查询
match查询：match查询会做分词处理，比如"宝马多少马力"会被分词为"宝马 多少 马力", 所有有关"宝马 多少 马力", 那么所有包含这三个词中的一个或多个的文档就会被搜索出来。
match_phrase查询：关键点（slop参数）短语匹配,es会根据分词的position对分词进行过滤，这个是就slop参数，默认是0
scroll分页：关键点（size分页）查询时可根据size数做分页操作。

public function searchDataPaginateFromEsByConditions($tableName,array $conditions){$params = ['scroll' => '1m','size'=>20,'index' => $tableName,'body'=> ['query' => $conditions,'sort'=> ['create_time'=>'desc']]];$client = $this->getEsClient();try{$result = $client->search($params);$list = [];$i=1;while (isset($result['hits']['hits']) && count($result['hits']['hits']) > 0 && $i <= 20){$list[] = $result['hits']['hits'];$scroll_id = $result['_scroll_id'];$result = $client->scroll(['body' => ['scroll_id' => $scroll_id,'scroll'=> '1m']]);$i++;}}catch (\Exception $exception){return $exception->getMessage()$list = [];}return $list;}
