Here's a PHP sample that will print progress to the console.  Note that the first time your notifyProgress gets called the array will only contain an objectId.  On subsequent calls it will include 'currentBytes', 'totalBytes', and 'startTime'.  
 require_once 'EsuRestApi.php'; require_once 'EsuHelpers.php';   class ProgressPrinter implements ProgressListener {     public function notifyProgress( array $progress, array &$results = null ) {             if(array_key_exists("objectId", $progress)) {                 print "New object created with ID " . $progress['objectId'] . "\n";             } else {                 print $progress['currentBytes'] . "/" . $progress['totalBytes'] . "\n";             }         }     public function notifyDone( array $progress = null, array &$results = null ) {             print "Transfer Complete.\n";         }     public function notifyError( array $progress = null, $exception ) {             print "Error: " . $exception;         }   }   $uid = 'f7412474230c40e4a293fc8aa2b0ac2e/user1'; $secret = 'K/IFTKQjLh/uAac0e14VkYueL0o='; $host = 'your_atmos_host'; $port = 80;   $atmos = new EsuRestApi( $host, $port, $uid, $secret ); $file_to_upload = $argv[1]; $dest = new ObjectPath($argv[2]);   print "Uploading $file_to_upload to $dest\n";   $helper = new UploadHelper($atmos); $helper->setListener(new ProgressPrinter()); $helper->createObjectFromFileOnPath($dest, $file_to_upload);  ?>  Running this sample will produce output like this:  ussaaharoml1c:src cwikj$ php UploadTest.php ~/Downloads/jdk-6u38-linux-x64.bin /test1/jdk-6u38-linux-x64.bin Uploading /Users/cwikj/Downloads/jdk-6u38-linux-x64.bin to /test1/jdk-6u38-linux-x64.bin New object created with ID 50ef37daa3068f5a050ef505e452000518bc3c903248 0/72058033 4194304/72058033 8388608/72058033 12582912/72058033 16777216/72058033 20971520/72058033 25165824/72058033 29360128/72058033 33554432/72058033 37748736/72058033 41943040/72058033 46137344/72058033 50331648/72058033 54525952/72058033 58720256/72058033 62914560/72058033 67108864/72058033 71303168/72058033 72058033/72058033 Transfer Complete. ussaaharoml1c:src cwikj$ 
Hello All,   Is there a function to call/set in Atmos-php to display live progression status of upload and download task? This is useful to provide a visible feedback to user about their transfer condition/state.   Notably there are functions such as ProgressListener, SetListener, notifyProgress and have no clue how to leverage on them.   Is anyone implemented something similar and able to share the approach here? Appreciate that!   Thank you!   Jason Cwik
