恕在下才疏学浅,是在不知道怎么组装语句来做前言了,那就粗鄙一点点吧.PHP 牛逼！ElasticSearch 牛逼！PHP + ElasticSearch 牛逼逼！！！

cd test
mkdir es
composer init
# 遇到选填空的就```键入n```,其他都回车就行

下载PHP自动加载类

composer dump-autoload

版本要求

安装ES-PHP

vim composer.json
# 添加
{
    "require":{
        "elasticsearch/elasticsearch":"^7.0"
    }
}
# 下载
composer install  

ID 查询

<?php

#包含自动加载文件
require 'vendor/autoload.php';
#使用elasticsearch-php
use Elasticsearch\ClientBuilder;
# 请求参数
$params = [
    "index" => "small_video",
    "type" => "_doc",
    "id" => 1
];
# 实例化ES
$client = ClientBuilder::create()
    ->setHosts(['127.0.0.1:8101'])
    ->build();
$result = $client->get($params);
print_r($result);

结果

# 执行文件
php index.php
# 显示结果
Array
(
    [_index] => small_video
    [_type] => _doc
    [_id] => 1
    [_version] => 2
    [_seq_no] => 18
    [_primary_term] => 3
    [found] => 1
    [_source] => Array
        (
            [name] => 二滑大魔王
            [content] => 你好啊
        )

)

Query 查询

# 懒癌又发作了 ...
cp index.php query.php
vim query.php

添加

<?php

#包含自动加载文件
require 'vendor/autoload.php';
#使用elasticsearch-php
use Elasticsearch\ClientBuilder;
# 请求参数
$params = [
    "index" => "small_video",
    "type" => "_doc",
    'body' => [
        'query' => [
            'multi_match' => [
                'query' => '二了',
                'fields' => ['name','content']
            ]
        ]
    ]
];
# 实例化ES
$client = ClientBuilder::create()
    ->setHosts(['127.0.0.1:8101'])
    ->build();
# 注意!!!这里用的是 search 而不是 get 了
# $result = $client->get($params);
$result = $client->search($params);
print_r($result);
