PHP中使用Elasticsearch

composer require elasticsearch/elasticsearch

會自動加載合適的版本！我的php是5.6的，它會自動加載5.3的elasticsearch版本！

Using version ^5.3 for elasticsearch/elasticsearch ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 4 installs, 0 updates, 0 removals   - Installing react/promise (v2.7.0): Downloading (100%)            - Installing guzzlehttp/streams (3.0.0): Downloading (100%)            - Installing guzzlehttp/ringphp (1.1.0): Downloading (100%)            - Installing elasticsearch/elasticsearch (v5.3.2): Downloading (100%)          Writing lock file Generating autoload files

簡單使用

<?php  class MyElasticSearch {     private $es;     // 構(gòu)造函數(shù)     public function __construct()     {         include('../vendor/autoload.php');         $params = array(             '127.0.0.1:9200'         );         $this->es = ElasticsearchClientBuilder::create()->setHosts($params)->build();     }      public function search() {         $params = [             'index' => 'megacorp',             'type' => 'employee',             'body' => [                 'query' => [                     'constant_score' => [ //非評分模式執(zhí)行                         'filter' => [ //過濾器，不會計算相關(guān)度，速度快                             'term' => [ //精確查找，不支持多個條件                                 'about' => '譚'                             ]                         ]                      ]                 ]             ]         ];          $res = $this->es->search($params);          print_r($res);     } }

<?php require "./MyElasticSearch.php";  $es = new MyElasticSearch();  $es->search();

Array (     [took] => 2     [timed_out] =>      [_shards] => Array         (             [total] => 5             [successful] => 5             [skipped] => 0             [failed] => 0         )      [hits] => Array         (             [total] => 1             [max_score] => 1             [hits] => Array                 (                     [0] => Array                         (                             [_index] => megacorp                             [_type] => employee                             [_id] => 3                             [_score] => 1                             [_source] => Array                                 (                                     [first_name] => 李                                     [last_name] => 四                                     [age] => 24                                     [about] => 一個PHP程序員，熱愛編程，譚康很帥，充滿激情。                                     [interests] => Array                                         (                                             [0] => 英雄聯(lián)盟                                         )                                  )                          )                  )          )  )
