      Copying objects

      Feature description

      This API is used to copy an object. It calls the PUT Object - Copy API for small files, and the Upload Part - Copy API for large files. This API is usually used to modify object attributes. For the parameters required, see those of the PUT Object - Copy and Upload Part - Copy APIs.

      Moving an Object

      Object movement involves copying the source object to the target location and deleting the source object.
      Since COS uses the bucket name (Bucket) and object key (ObjectKey) to identify objects, moving an object will modify the object identifier. COS’s PHP SDK does not provide a stand-alone API to modify object identifiers. However, you can still move the object with a combination of basic operations (object copy and object delete).
      For example, if you want to move the picture.jpg object to the “doc” directory that is in the same bucket (mybucket-1250000000), you can copy the picture.jpg to the “doc” directory (making the object key doc/picture.jpg) and then delete the source object.
      Likewise, if you need to move picture.jpg in the mybucket-1250000000 bucket to another bucket myanothorbucket-1250000000, you can copy the object to the myanothorbucket-1250000000 bucket first and then delete the source object.

      Sample code

      //: # ".cssg-snippet-move-object"
      <?php
      
      require dirname(__FILE__) . '/../vendor/autoload.php';
      
      $secretId = "SECRETID"; //Replace it with the actual `SecretId`, which can be viewed and managed in the CAM console at https://console.tencentcloud.com/cam/capi
      $secretKey = "SECRETKEY"; //Replace it with the actual `SecretKey`, which can be viewed and managed in the CAM console at https://console.tencentcloud.com/cam/capi
      $region = "ap-beijing"; //Replace it with the actual `region`, which can be viewed in the console at https://console.tencentcloud.com/cos5/bucket
      $cosClient = new Qcloud\\Cos\\Client(
          array(
              'region' => $region,
              'schema' => 'https', // Protocol header, which is http by default
              'credentials'=> array(
                  'secretId'  => $secretId ,
                  'secretKey' => $secretKey)));
      
      try {
          $cosClient->copy(
              $bucket = 'examplebucket-125000000', // Bucket name in the format of `BucketName-APPID`, which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
              $key = 'exampleobject',
              $copySource = array(
                  'Region' => '<sourceRegion>',

                  'Key' => '<sourceKey>', 
              )
          );
          $result = $cosClient->deleteObject(array(
              'Bucket' => 'examplebucket-125000000', // Bucket name in the format of `BucketName-APPID`, which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
