php 使用 ElasticSearch/es 的最佳实践

PHP 使用elasticsearch

composer require elasticsearch/elasticsearch

会自动加载合适的版本！我的php是7.1的，它会自动加载7.9的elasticsearch版本！

elasticsearch的简单使用：

例子1：

<?php

require 'vendor/autoload.php';
use Elasticsearch\ClientBuilder;

//https://www.elastic.co/guide/cn/elasticsearch/php/current/_quickstart.html#_quickstart
//$client = ClientBuilder::create()->build();
//如果没有设置主机地址默认为127.0.0.1:9200
$client = Elasticsearch\ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
//var_dump($client);
//索引一个文档
echo '索引一个文档'.PHP_EOL;
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id',
    'body' => ['testField' => 'abc']
];
$response = $client->index($params);
pr($response);

//获取一个文档
echo '获取一个文档'.PHP_EOL;
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id'
];

$response = $client->get($params);
pr($response);
echo '搜索一个文档'.PHP_EOL;
//搜索一个文档
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        'query' => [
            'match' => [
                'testField' => 'abc'
            ]
        ]
    ]
];

$response = $client->search($params);
pr($response);


//DIE;
echo '删除一个文档'.PHP_EOL;
//删除一个文档
$params = [
    'index' => 'my_index',
    'type' => 'my_type',
    'id' => 'my_id'
];
$response = $client->delete($params);
pr($response);

echo '删除一个索引'.PHP_EOL;
//删除一个索引
$deleteParams = [
    'index' => 'my_index'
];
$response = $client->indices()->delete($deleteParams);
pr($response);


echo '创建一个索引'.PHP_EOL;
//创建一个索引
$params = [
    'index' => 'my_index',
    'body' => [
        'settings' => [
            'number_of_shards' => 2,
            'number_of_replicas' => 0
        ]
    ]
];

$response = $client->indices()->create($params);
pr($response);

function pr($response){
    echo '<pre>';
    print_r($response);
    echo '</pre>';
}
