开放存储服务（openstorageservice，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。用户可以通过简单的api（rest方式的接口），在任何时间、任何地点、任何互联网设备上进行数据上传和下载。
首先、登录阿里云首页http://www.aliyun.com/ 免费开通服务。
开通以后，进入管理控制台--进入开发存储服务oss,进入到控制台。
其次、下载sdk http://bbs.aliyun.com/job.php?action=download&aid=41064
解压后在samples文件夹内新建一个index.php文件
$accesskeyid,      //accesskeyid在“用户中心”--“我的服务”--“安全认证”
        'accesskeysecret' => $accesskeysecret,
    ));
}
//获取所有bucket
//bucket是水桶的意思，可以理解为容器，里面装了各种各样的东西，也就是key=>value
function listbuckets(ossclient $client) {
     $buckets = $client->listbuckets();
     foreach ($buckets as $bucket) {
          echo 'bucket: ' . $bucket->getname() . \n;
     }
}
//新建bucket
function createbucket(ossclient $client, $bucket) {
     $client->createbucket(array( 'bucket' => $bucket, ));
 }
// sample of get bucket acl
function getbucketacl(ossclient $client, $bucket) {
     $acl = $client->getbucketacl(array( 'bucket' => $bucket, ));
     $grants = $acl->getgrants(); echo $grants[0];
}
//获取bucket的所有key
function getbucketkey(ossclient $client, $bucket){
    $objectlisting = $client->listobjects(array( 'bucket' => $bucket, ));
    foreach ($objectlisting->getobjectsummarys() as $objectsummary) {
        $objectsummary->getkey();
    }
}
//向某个bucket上传内容，可以字符串或者文件
function upload(ossclient $client, $bucket,$key,$content,$type){
      isset($type)?$type:0;
      if($type == 0){
           $type = gettype($content);
           //如果上传内容为数组或者对象，需要进行序列化
           if($type == array || $type == object) {
                $content = serialize($content);
           }
           $client->putobject(array( 'bucket' => $bucket, 'key' => $key, 'content' => $content, ));
      }else{
          $client->putobject(
                   array( 'bucket' => $bucket,
                          'key' => $key,
                          'content' => fopen($content, 'r'),
                          'contentlength' => filesize($content),
                   ));
      }
}
//下载文件
function download(ossclient $client, $bucket, $key){
      $object = $client->getobject(
          array( 'bucket' => $bucket,
                 'key' => $key,
          ));
      echo (string)$object;
}
// 删除bucket
function deletebucket(ossclient $client, $bucket) {
      $client->deletebucket(
               array( 'bucket' => $bucket, ));
 }
$keyid = '5wtgmhx6mqx6q***';
$keysecret = 'vdisrnuhey0thb9v1ryv08vj4lc***';
$client = createclient($keyid, $keysecret);
$bucket = 'xiaoqiangbucket';
$key = rand(1,1000);
$content = this is xiaoqiang's content;
//$content = array(1,2,3,4,5,6,7,8);
listbuckets($client); //显示所有bucket
createbucket($client, $bucket); //新建一个bucket
getbucketacl($client, $bucket);
download($client, $bucket, $key); //下载key为$key的content
upload($client, $bucket, $key, $content,0); //上传$key=>$content到bucket
var_dump(getbucketkey($client, $bucket));//显示bucket内的所有key
//deletebucket($client, $bucket)； //删除bucket
 至此在客户端实现了控制台的所有操。
