in recursive way.

$message=get_files("UserIds/".$Username);
function get_files($dir){
    $message=array();

    $folder=dir($dir);
    while($folderEntry=$folder->read())
    {
       if($folderEntry !=".." && $folderEntry !=".")
       {   

          $message[]="http://www.myappdemo.com/appinstaller/".$dir."/".$folderEntry;
          if (is_dir($dir."/".$folderEntry)){
             $new_message=get_files($dir."/".$folderEntry);
             if (is_array($new_message)){
                 $message=array_merge($message,$new_message);
             }
          }
       }
    }
    $folder->close();
  return $message;
}

If you replace your

while($folderEntry=$folder->read())
{
     if($folderEntry !=".." && $folderEntry !=".")
     {   
         $message[$i]="http://www.myappdemo.com/appinstaller/UserIds/$number/".$folderEntry;
         $i++;
     } 
}

with

while (false !== ($folderEntry = $folder->read())) {
    if($folderEntry !=".." && $folderEntry !=".")
    {   
        $message[$i]="http://www.myappdemo.com/appinstaller/UserIds/$number/".$folderEntry;
        $i++;
    }
}

I think you're there.

And I can't see your setting $Username anywhere I reckon $folder=dir("UserIds/".$Username."/"); should be $folder=dir("UserIds/".$number."/"); as well.

Ever heard of recursivity? :)
