1、声明依赖关系：

比方说，你的项目中需要一个php版的elasticsearch框架。为了将它添加到你的项目中（下载），你所需要做的就是创建一个 composer.json 文件，其中描述了项目的依赖关系。注意文件要放在你执行composer命令的目录中

{
    "require":{
        "elasticsearch/elasticsearch":"~2.0"
    }
}

2、cmd切换到要下载elasticsearch框架的目录，然后执行命令：composer install

如有出错误信息：

[Composer\Downloader\TransportException]

Content-Length mismatch, received 583439 bytes out of the expected 1215108

解决办法：切换国内镜像地址，再执行操作

1、通过命令切换如下：（最终修改的是composer.json）

composer config -g repo.packagist composer https://packagist.phpcomposer.com

2、直接修改 composer.json （其实跟方法1是一样的。）

{
    "require":{
        "elasticsearch/elasticsearch":"~2.0"
    },
    "repositories": {
        "packagist": {
            "type": "composer",
            "url": "https://packagist.phpcomposer.com"
        }
    }
}

Elasticsearch全文搜索引擎-PHP使用教程

PHP使用elasticsearch教程：

想直接通过文件查看其他方法可以打开以下文件查看（基本使用的方法都在里面）：

1、\elasticsearch\src\Elasticsearch\Client.php中的方法

2、\elasticsearch\Namespaces\IndicesNamespace.php中的方法

其他形式用法测试：

    $sql    = "SELECT * FROM emp";  
    $conn   = get_conn();  
    $stmt   = $conn->query($sql);  
    $rtn    = $stmt->fetchAll();  
   
   
    //delete index which already created  
    $params = array();  
    $params['index'] = 'emp_index';  
    $client->indices()->delete($params);  
       
    //create index on log_date,src_ip,dest_ip  
    $rtnCount = count($rtn);  
    for($i=0;$i<$rtnCount;$i++){  
        $params = array();  
        $params['body'] = array(

        $params['index'] = 'emp_index';  
        $params['type']  = 'emp_type';  
           
        //Document will be indexed to log_index/log_type/autogenerate_id          
        $client->index($params);

    $params['size'] = 3;    
    $params['from'] = 1;    
    $rtn = $client->search($params);  
    var_dump($rtn);  
}  
set_time_limit(0);  
// create_index();  
search();  
?>

1）创建：

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);

2）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);

3）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;

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);  
 
#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;

4）删除文档：

include('./vendor/autoload.php');  
$elastic = new Elasticsearch\Client();  
$index['index'] = 'test';  //索引名称  
$index['type'] = 'ems_test'; //类型名称  
$index['id'] = 2;   
$elastic->delete($index);

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;

4）删除文档：

include('./vendor/autoload.php');  
$elastic = new Elasticsearch\Client();  
$index['index'] = 'test';  //索引名称  
$index['type'] = 'ems_test'; //类型名称  
$index['id'] = 2;   
$elastic->delete($index);
