trying to get emails from Distribution list in CPM

Content

i have created a distribution list in RNT Console trying to get those email address in CPM to use them in MailMessage, i am using this code but it is not working.

$roql_result_set = RNCPHP\ROQL::query( "SELECT Email FROM DistributionEmailList where name = '<Distribution List name>'" );

while($roql_result = $roql_result_set->next())
{
    while ($row = $roql_result->next())
  {  
    $distro = $distro.$row;
    }
}

 

i get an "Array" String when i print $distro but not sure how to get email list. i would like to use $distro in below code:

$mm = new RNCPHP\MailMessage();
$mm->To->EmailAddresses = array($distro);
