 ## 概述
 
 阿里云对象存储（Object Storage Service，简称OSS），是阿里云对外提供的海量、安全、低成本、高可靠的云存储服务。用户可以通过调用API，在任何应用、任何时间、任何地点上传和下载数据，也可以通过用户Web控制台对数据进行简单的管理。OSS适合存放任意文件类型，适合各种网站、开发企业及开发者使用。

 ### 存储空间操作
 
 存储空间(又称Bucket)是一个用户用来管理所存储Object的存储空间,对于用户来说是一个管理Object的单元，所有的Object都必须隶属于某个Bucket。您可以按照下面的代码新建一个Bucket：
-   
+
 ```php
 <?php
 $bucket = "<您使用的Bucket名字，注意命名规范>";
 try {
-	$ossClient->createBucket($bucket);
+    $ossClient->createBucket($bucket);
 } catch (OssException $e) {
