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 ElasticsearchClient();
创建索引
- include(‘./vendor/autoload.php‘);
- $elastic = new ElasticsearchClient();
- $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 ElasticsearchClient();
- $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 ElasticsearchClient();
- $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 ElasticsearchClient();
- $index[‘index’] = ‘log’; //索引名称

- array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),
- array(‘match’ => array(‘product_id’ => 20))
- );
- $index[‘size’] = 10;
- $index[‘from’] = 200;
- $elastic->search($index);

- array(‘match’ => array(‘mac’ => ‘fcd5d900beca’)),
- array(‘match’ => array(‘product_id’ => 20))
- );
- $index[‘size’] = 10;
- $index[‘from’] = 200;
- $elastic->search($index);
- 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 ElasticsearchClient();

- 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 ElasticsearchClient();
- $index[‘index’] = ‘log’; //索引名称

- );
- $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;
