Not currently.  However, you could easily change this by moving the setting of currentBytes to zero to the constructor and adding a setCurrentBytes() function that you would call before readObjectToXXX.
Following two PHP functions taking care of downloading a file from online EMC storage:   readObjectToFile readObjectToStream   However, there is a code assigning the current bytes value to 0, $this->currentBytes = 0; Is there a way to specify offset value similar to uploading operation, in order to achieve a download resume operation?   Jason Cwik , any light to share, please?   Thank you.
