Unable to delete phone numbers in Twilio REST API in PHP - php

Question

Hi I keep geting the following error when I try to delete a number from my twilio subaccount using REST API in PHP
my code is;
$number = $twClient->account->incoming_phone_numbers->get($number_Sid);
$twClient->account->incoming_phone_numbers->delete($number->sid);
The error that I am getting is;

Answer 1

If you have already successfully deleted the phone number, Twilio will return a 404 Not Found to you, which the PHP library will interpret as a RestException. You can only delete the phone number one time :)

Answer 2

You can override exception by using this syntax:
try
{
// do something that can go wrong
}
catch (Exception $e)
{
throw new Exception( 'Something really gone wrong', 0, $e);
}
Here's another live sample for sending messages with an exception catcher:
<?PHP
require "Services/Twilio.php";
// Set our AccountSid and AuthToken from twilio.com/user/account
$AccountSid = "{ACCOUNTSID}";
$AuthToken = "{AUTHTOKEN}";
// Instantiate a new Twilio Rest Client
$client = new Services_Twilio($AccountSid, $AuthToken);
/* Your Twilio Number or Outgoing Caller ID */
$from = '2126404004';
$people = array("212-716-1130");
$body = "Enter your text message here";
$errorIds = array(); //user ids array which had broken phones
foreach ($people as $to) {
try
{
$client->account->sms_messages->create($from, $to, $body);
echo "Sent message to: $to \n <br>";
}
catch (Exception $e)
{ //on error push userId in to error array
$count++;
array_push($errorIds, $to);
}
}
print_r($errorIds);
?>
Without catching the exception, the script will die with an error like:
<br>PHP Fatal error: Uncaught exception 'Services_Twilio_RestException' with message 'The message From/To pair violates a blacklist rule.' in /var/www/vhosts/httpdocs/twilio/Services/Twilio.php:149
