Elasticsearch全文搜索引擎-PHP使用教程。

小川 2018-07-07 PHP

用Composer來生成php版的elasticsearch框架：

如果你還沒有安裝Composer的話請看：Composer安裝教程文章。

1、聲明依賴關係：

比方說，你的項目中需要一個php版的elasticsearch框架。爲了將它添加到你的項目中（下載），你所需要做的就是創建一個 composer.json 文件，其中描述了項目的依賴關係。注意文件要放在你執行composer命令的目錄中

{

"require":{

"elasticsearch/elasticsearch":"~2.0"

}

2、cmd切換到要下載elasticsearch框架的目錄，然後執行命令：composer install

如有出錯誤信息：

[Composer\Downloader\TransportException]

Content-Length mismatch, received 583439 bytes out of the expected 1215108

解決辦法：切換國內鏡像地址，再執行操作

1、通過命令切換如下：（最終修改的是composer.json）

composer config -g repo.packagist composer https://packagist.phpcomposer.com

2、直接修改 composer.json （其實跟方法1是一樣的。）

{

"require":{

"elasticsearch/elasticsearch":"~2.0"

},

"repositories": {

"packagist": {

"type": "composer",

"url": "https://packagist.phpcomposer.com"

}

PHP使用elasticsearch教程：

下面我們講一下基本使用方法，需要獲取更多使用教程和方法請看官方文檔：https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/_overview.html

想直接通過文件查看其他方法可以打開以下文件查看（基本使用的方法都在裏面）：

1、\elasticsearch\src\Elasticsearch\Client.php中的方法

2、\elasticsearch\Namespaces\IndicesNamespace.php中的方法

ThinkPHP中的模型（已測試過）：

其他形式用法測試：

test.php

<?php

require_once('vendor/autoload.php');

use Elasticsearch\ClientBuilder;

function get_conn(){

$host = 'localhost';

$dbname = 'mraz';

$user = 'root';

$passwd = '111111';

$conn = new PDO("mysql:dbname=$dbname;host=$host",$user,$passwd);

return $conn;

}

function create_index(){

//Elastic search php client

$client = Elasticsearch\ClientBuilder::create()->build();

$sql = "SELECT * FROM emp";

$conn = get_conn();

$stmt = $conn->query($sql);

$rtn = $stmt->fetchAll();

//delete index which already created

$params = array();

$params['index'] = 'emp_index';

$client->indices()->delete($params);

//create index on log_date,src_ip,dest_ip

$rtnCount = count($rtn);

for($i=0;$i<$rtnCount;$i++){

$params = array();

$params['body'] = array(

'id' => $rtn[$i]['id'],

'fdName' => $rtn[$i]['fdName'],

'fdAge' => $rtn[$i]['fdAge'],

'fdStatus' => $rtn[$i]['fdStatus']

);

$params['index'] = 'emp_index';

$params['type'] = 'emp_type';

//Document will be indexed to log_index/log_type/autogenerate_id

$client->index($params);

}

echo 'create index done!';

}

function search(){

//Elastic search php client

$client = Elasticsearch\ClientBuilder::create()->build();

$params = array();

$params['index'] = 'emp_index';

$params['type'] = 'emp_type';

$params['body']['query']['match']['fdStatus'] = '1';

$params['body']['sort'] = array('fdAge'=>array('order'=>'desc'));

$params['size'] = 3;

$params['from'] = 1;

$rtn = $client->search($params);

var_dump($rtn);

}

set_time_limit(0);

// create_index();

search();

?>

1）創建：

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$data['body']['settings']['number_of_shards'] = 5; //主分片數量

$data['body']['settings']['number_of_replicas'] = 0; //從分片數量

$elastic->indices()->create($index);

2）插入索引數據：

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['id'] = 1 //不指定id，系統會自動生成唯一id

$index['body'] = array(

'mac' => 'fcd5d900beca',

'customer_id' => 3,

'product_id' => 5,

'version' => 2

);

$elastic->index($index);

3）查詢：

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['body']['query']['match']['mac'] = 'fcd5d900beca';

$index['size'] = 10;

$index['from'] = 200;

$elastic->search($index);

#相當於sql語句:select*from ems_run_log where mac='fcd5d900beca' limit 200,10;

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['body']['query']['bool']['must'] = array(

array('match' => array('mac' => 'fcd5d900beca')),

array('match' => array('product_id' => 20))

);

$index['size'] = 10;

$index['from'] = 200;

$elastic->search($index);

#相當於sql語句:select*from ems_run_log where mac='fcd5d900beca' and product_id=20 limit 200,10;

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['body']['query']['bool']['should'] = array(

array('match' => array('mac' => 'fcd5d900beca')),

array('match' => array('product_id' => 20))

);

$index['size'] = 10;

$index['from'] = 200;

$elastic->search($index);

#當於sql語句:select*from ems_run_log where mac='fcd5d900beca' or product_id=20 limit 200,10;

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['body']['query']['bool']['must_not'] = array(

array('match' => array('mac' => 'fcd5d900beca')),

array('match' => array('product_id' => 20))

);

$index['size'] = 10;

$index['from'] = 200;

$elastic->search($index);

#相當於sql語句:select*from ems_run_log where mac!='fcd5d900beca' and product_id!=20 limit 200,10;

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['body']['query']['range'] = array(

'id' => array('gte' => 20,'lt' => 30);

);

$index['size'] = 10;

$index['from'] = 200;

$elastic->search($index);

#相當於sql語句:select*from ems_run_log where id>=20 and id<30 limit 200,10;

4）刪除文檔：

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'test'; //索引名稱

$index['type'] = 'ems_test'; //類型名稱

$index['id'] = 2;

$elastic->delete($index);

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['body']['query']['bool']['must_not'] = array(

array('match' => array('mac' => 'fcd5d900beca')),

array('match' => array('product_id' => 20))

);

$index['size'] = 10;

$index['from'] = 200;

$elastic->search($index);

#相當於sql語句:select*from ems_run_log where mac!='fcd5d900beca' and product_id!=20 limit 200,10;

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'log'; //索引名稱

$index['type'] = 'ems_run_log'; //類型名稱

$index['body']['query']['range'] = array(

'id' => array('gte' => 20,'lt' => 30);

);

$index['size'] = 10;

$index['from'] = 200;

$elastic->search($index);

#相當於sql語句:select*from ems_run_log where id>=20 and id<30 limit 200,10;

4）刪除文檔：

include('./vendor/autoload.php');

$elastic = new Elasticsearch\Client();

$index['index'] = 'test'; //索引名稱

$index['type'] = 'ems_test'; //類型名稱

$index['id'] = 2;

$elastic->delete($index);
