Using a variable outside PHP Foreach Loop - arrays

Question

I am trying to output a username and user email outside of a foreach loop. I am trying to send an email to all WordPress users that are within a certain User Role.
Here is my code:
// Get users and their roles
$user_args = array(
'role__in' => 'new_role',
'orderby' => 'user_nicename',
'order' => 'ASC'
);
$users = get_users($user_args);
foreach ( $users as $user ) :
$user_name = $user->user_email;
$user_email = $user->display_name;
endforeach;
So I can then use them in other areas of the page, ie:.
echo 'Hello, ' . $user_name;
echo 'Send to: ' .$user_email;
I've printed out the $users array which contains the following:
Array
(
[0] => WP_User Object

[data] => stdClass Object

If you want to send an email to all users with a certain role, try something like this:
// Get users and their roles
$user_args = array(
'role__in' => 'new_role',
'orderby' => 'user_nicename',
'order' => 'ASC'
);
$users = get_users($user_args);
foreach ( $users as $user ) :
$user_email = $user->user_email;
$user_name = $user->display_name;
send_email($user_name, $user_email);
endforeach;
And then write your email function:
function send_email($name, $email) {
// Do email sending stuff here with $name & $email
}
