PHP: Error handling without throwing an exception - php

Question

I'm sending multiple emails from a PHP application, and I want to inform the user of the emails that failed to be sent.
What is the most elegant way to do the error handling when
I don't want to throw an exception that terminates the sending of the remaining emails
The call goes through several method calls
What I want is to get the $notificationSucceeded back from Suggestion::notifyDeletionToAll() to SuggestionController somehow nicely from all notifications.
The depth of the call stack made me doubt if returning it through all the methods is the most elegant way, especially when I already have a return value from Suggestion::cancel().
Is there a better way?
Controller:
class SuggestionController {
function cancelSuggestion($suggestionId)
{
$suggestion = new Suggestion();
$suggestion->fetch($suggestionId);
$suggestionDeleted = $suggestion->cancel();
print json_encode(array(
'status' => 'ok',
'suggestionDeleted' => $suggestionDeleted,
));
}
}
Suggestion class:
class Suggestion {
/**
* Cancels membership of current user in the suggestion
*/
public function cancel()
{
$this->cancelMembership();
if (!$this->hasAcceptedMembers()) {
$this->deleteAndNotify();
return true;
}
return false;
}
/**
* Deletes the suggestion and notifies all the users in it
*/
private function deleteAndNotify()
{
$this->notifyDeletionToAll();
DB::inst()->query("DELETE FROM suggestions WHERE id = {$this->id}");
}
/**
* Notifies about the deletion of the suggestion to all members (users in the suggestion)
*/
private function notifyDeletionToAll()
{
$result = DB::inst()->query("SELECT user_id FROM suggestions_users
WHERE suggestion_id = {$this->id}");
while ($member_id = DB::inst()->fetchFirstField($result)) {
$member = new User();
$member->fetch($member_id);
$notificationSucceeded = $member->notifySuggestionDeleted($this);
}
}
}

I can't understand your question clearly. but i hope this will help you
$successfully_sent_arr = array();
$failure_notsent_arr = array();
if($mail->Send())
{
$successfully_sent_arr[] = $to_email;
//Once the last loop occurs, update this array in database
}
else
{
$failure_notsent_arr[] = $to_email;
//Once the last loop occurs, update this array in database
}
