I am using twilio to send bulk sms messages. Let's say some customer decided that they don't want to receive messages anymore so they reply with "stop" and that will add them to the black list. I am hard coding the phone numbers because I am still testing on my own cell phones. I noticed that when I do not remove the numbers on the black list from my code, I am getting an error message and my script stops at that point.
In the future, I will probably be using numbers stored in a database or a file. In that case, how do I overcome this problem if it happened. Basically what I want to do is: If a number is in the black list, move on to the next number and avoid that error using an exception or something. The error message and code is below.
Thanks,

You need to catch the exception that is thrown from the request to send a message to the blacklisted number. You can do so with try and catch like this:
foreach ($people as $number => $name) {
try {
$sms = $client->account->messages->create(
$number,
array(
'from' => "+18443949780",
'body' => "Hey $name, this is Hussam. Testing Twilio SMS API!"
)
);
echo "Sent message to $name.\n";
} catch (\Twilio\Exceptions\RestException $e) {
echo "Couldn't send message to $number\n";
}
}
When you hook this up to a database, you'll want to use the catch to update a field to mark the number as blocked so that you don't try to send to it again.
Let me know if that helps at all.

This worked for me with Laravel 5. Notice the use of \Twilio\Exceptions\RestException.
try {
$sms = $client->account->messages->create(
$number,
array(
'from' => "+16136543180",
'body' => "Hey $name, Are you still mad at us about your cat!"
)
);
echo "Sent message to $name.\n";
} catch (\Twilio\Exceptions\RestException $e) {
if ($e->getCode() == 20404) {
//this will be false condition
dd('False Result 404');
} else {
//some other exception code
dd($e->getMessage());
}
}
