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：
[ComposerDownloaderTransportException]
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。）

PHP使用elasticsearch教程：
下面我们讲一下基本使用方法，需要获取更多使用教程和方法请看官方文档：https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/_overview.html
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、elasticsearchsrcElasticsearchClient.php中的方法
2、elasticsearchNamespacesIndicesNamespace.php中的方法
ThinkPHP中的模型（已测试过）：
