Here's a method which can scan directories recursively and return multi-dimensional arrays if the recursive parameter is set, or only scan the path and return a single dimension array containing files in that directory if it's not. Can be modified to also include directories without contents in non-recursive mode if needed.

Creating it as a class makes it easy to be reused later. I only included the methods from my class that were required to answer the question.

$host      = 'example.com';
$port      = 22;
$username  = 'user1';
$password  = 'password123';
$path      = '.';
$recursive = true;

$conn = new SFTP($host, $port);
$conn->login($username, $password);
$files = $conn->ls($path, $recursive);
var_dump($files);

class SFTP
{
  private $connection;
  private $sftp;

  public function __construct($host, $port = 22)
  {
    $this->connection = @ssh2_connect($host, $port);
    if (! $this->connection)
      throw new Exception("Could not connect to $host on port $port.");
  }

  public function login($username, $password)
  {
    if (! @ssh2_auth_password($this->connection, $username, $password))
      throw new Exception("Could not authenticate with username $username");
    $this->sftp = @ssh2_sftp($this->connection);
    if (! $this->sftp)
      throw new Exception("Could not initialize SFTP subsystem.");
  }

  public function ls($remote_path, $recursive = false)
  {
    $tmp      = $this->sftp;
    $sftp     = intval($tmp);
    $dir      = "ssh2.sftp://$sftp/$remote_path";
    $contents = array();
    $handle   = opendir($dir);

    while (($file = readdir($handle)) !== false) {
      if (substr("$file", 0, 1) != "."){
        if (is_dir("$dir/$file")){
          if ($recursive) {
            $contents[$file] = array();
            $contents[$file] = $this->ls("$remote_path/$file", $recursive);
          }
        } else {
          $contents[] = $file;
        }
      }
    }

    closedir($handle);
    return $contents;
  }
}
