php elasticsearch基础使用
elasticsearch的操作都是基于http协议的,已经有现成的php类库，composer安装即可。
{
"require": {
"elasticsearch/elasticsearch": "^6.7"
}
}(1).先封装一个简单的操作
class Es
{
/**
* Es_Hosts
* @var array
*/
private $hosts = ['127.0.0.1:9200'];
/**
* Es_hander
* @var null
*/
private $hander = null;
/**
* Es constructor.
*/
public function __construct()
{
$this->hander = \Elasticsearch\ClientBuilder::create()->setHosts($this->hosts)->build();
}
/**
* 索引一个文档(相当于mysql新增)
* @param array $data 索引的数据
* @return array
*/
public function add($data)
{
$inputData = [
'index' => 'hq', //索引,相当于Mysql的数据库
'type' => 'hq_member', //索引,相当于Mysql的表
'body' => $data //添加的文档,相当于Mysql的记录
];
return $this->hander->index($inputData);
}
/**
* 批量索引文档(相当于mysql批量新增)
* @param array $allData 批量索引的数据
* @return array
*/
public function addAll($allData)
{
$inputData = [];
foreach ($allData as $data)
{
$inputData['body'][] = [
'index' => [
'_index' => 'hq', //索引,相当于Mysql的数据库
'_type' => 'hq_member', //索引,相当于Mysql的表
]
];
$inputData['body'][] = $data;
}
return $this->hander->bulk($inputData);
}
/**
* 获取一个文档(相当于mysql查询记录)
* @param string $id 文档id
* @return array|bool
*/
public function get($id)
{
$inputData = [
'index' => 'hq', //索引,相当于Mysql的数据库
'type' => 'hq_member', //索引,相当于Mysql的表
'id' => $id //文档的id
];
try
{
$result = $this->hander->get($inputData);
}
catch (\Elasticsearch\Common\Exceptions\Missing404Exception $exception)
{
//不存在的文档竟然抛出异常,有点2
return false;
}
return $result;
}
/**
* 搜索一个文档(相当于mysql搜索记录)
* @param string $word 搜索词
* @return array
*/
public function search($word)
{
$inputData = [
'index' => 'hq', //索引,相当于Mysql的数据库
'type' => 'hq_member', //索引,相当于Mysql的表
];
$inputData['body']['query']['match']['desc'] = $word;
return $this->hander->search($inputData);
}
/**
* 删除一个文档(相当于mysql删除记录)
* @param string $id 文档id
* @return array
*/
public function delete($id)
{
$inputData = [
'index' => 'hq', //索引,相当于Mysql的数据库
'type' => 'hq_member', //索引,相当于Mysql的表
'id' => $id, //文档id
];
return $this->hander->delete($inputData);
}
/**
* 创建索引名称(相当于mysql创建库)
* @param string $indexName 索引名
* @return array
*/
public function createIndex($indexName)
{
return $this->hander->indices()->create([
'index' => $indexName
]);
}
/**
* 删除索引名称(相当于mysql删库)
* @param string $indexName 索引名
* @return array
*/
public function deleteIndex($indexName)
{
return $this->hander->indices()->delete([
'index' => $indexName
]);
}
}(2).索引一个文档记录(相当于mysql的insert)
$oneData = ['name' => '张清喜', 'age' => 21, 'desc' => '江西的小伙子']; $ret = $es->add($oneData);
