浅谈PHP Elasticsearch的简单使用方法

本篇文章给大家介绍一下php中使用elasticsearch的简单方法。有一定的参考价值,有需要的朋友可以参考一下,希望对大家有所帮助。
推荐学习:《php视频教程》
php中使用elasticsearch
composer require elasticsearch/elasticsearch
会自动加载合适的版本!我的php是5.6的,它会自动加载5.3的elasticsearch版本!
using version ^5.3 for elasticsearch/elasticsearch./composer.json has been updatedloading composer repositories with package informationupdating 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 filegenerating autoload files
简单使用
<?phpclass myelasticsearch{ private $es; // 构造函数 public function __construct() { include('../vendor/autoload.php'); $params = array( '127.0.0.1:9200' ); $this->es = \elasticsearch\clientbuilder::create()->sethosts($params)->build();    }    public function search() {        $params = [            'index' => 'megacorp',            'type' => 'employee',            'body' => [                'query' => [                    'constant_score' => [ //非评分模式执行                        'filter' => [ //过滤器,不会计算相关度,速度快                            'term' => [ //精确查找,不支持多个条件                                'about' => '谭'                            ]                        ]                    ]                ]            ]        ];        $res = $this->es->search($params);        print_r($res);    }}
<?phprequire "./myelasticsearch.php";$es = new myelasticsearch();$es->search();
执行结果
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] => 一个php程序员,热爱编程,谭康很帅,充满激情。                                    [interests] => array                                        (                                            [0] => 英雄联盟                                        )                                )                        )                )        ))
下面是官方的一些样例整合,
<?phprequire '../vendor/autoload.php';use elasticsearch\clientbuilder;class myelasticsearch{ private $client; // 构造函数 public function __construct() { $params = array( '127.0.0.1:9200' );
