来源：互联网发布：奥卡福体测数据编辑：程序博客网时间：2024/06/06 13:13

PHP扩展安装

1. 环境要求：PHP_VERSION >= 5.3.9，composer工具

2. 在E盘新建文件夹命名为elastic,，拷贝composer.phar到
E:/elastic目录下面

3. 打开命令行窗口，进入E:/elastic

4. 在命令行运行：
php composer.phar require elasticsearch/elasticsearch

5. 此时E:/elastic目录下会出现一个vendor目录，安装成功

6. 使用方法：
require 'vendor/autoload.php';
$client = new Elasticsearch\Client();

创建索引

   include('./vendor/autoload.php');   $elastic = new Elasticsearch\Client();   $index[‘index’] = ‘log’;  //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $data[‘body’][‘settings’][‘number_of_shards’] = 5;  //主分片数量   $data[‘body’][‘settings’][‘number_of_replicas’] = 0; //从分片数量   $elastic->indices()->create($index);

插入索引数据

 include('./vendor/autoload.php');   $elastic = new Elasticsearch\Client();   $index[‘index’] = ‘log’; //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $index[‘id’] = 1   //不指定id，系统会自动生成唯一id   $index[‘body’] = array(       ‘mac’ => 'fcd5d900beca',       ‘customer_id’ => 3,       ‘product_id’ => 5,       ‘version’ => 2   );   $elastic->index($index);

查询

include('./vendor/autoload.php');   $elastic = new Elasticsearch\Client();   $index[‘index’] = ‘log’; //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $index[‘body’][‘query’][‘match’][‘mac’] = ‘fcd5d900beca’;   $index[‘size’] = 10;   $index[‘from’] = 200;   $elastic->search($index);  相当于sql语句：   select*from ems_run_log where mac=‘fcd5d900beca’   limit 200,10;<strong></strong>

 include('./vendor/autoload.php');   $elastic = new Elasticsearch\Client();   $index[‘index’] = ‘log’; //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $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);  相当于sql语句：   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’; //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $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);  相当于sql语句：   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’; //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $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);  相当于sql语句：   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’; //索引名称   $index[‘type’] = ‘ems_run_log’; //类型名称   $index[‘body’][‘query’][‘range’] = array(       ‘id’ => array(‘gte’ => 20,’lt’ => 30);     );   $index[‘size’] = 10;   $index[‘from’] = 200;   $elastic->search($index);  相当于sql语句：   select*from ems_run_log where id>=20   and id<30  limit 200,10;
