foreach ($authors as $author) {
array_push($user_email , $author->user_email );
}
}
}
else{
$to_users = $crm->vc_users;
$to_program = $crm->vc_program;
$to_group = $crm->vc_group;
$to_excode = $crm->vc_ex_code;
foreach ($to_users as $key => $value) {
$user_data = get_userdata($value);
array_push($user_email, $user_data->user_email);

foreach ($to_program as $key => $value) …
