Fatal error: Class 'Services_Twilio' not found - php

Question

I'm trying to send a text message when a form is submitted using Twilio's test account however I'm receiving the following error: 'Fatal error: Class 'Services_Twilio' not found'
My code is as follows:
} else{
//PHP native
mail( $to_guest, $subject, $html_text, $header_guest);
// Outlet Admin notification email
mail( $to_admin, $subject, $notification_text, $header_admin);
/* Send an SMS using Twilio. You can run this file 3 different ways:
*
* - Save it as sendnotifications.php and at the command line, run
* php sendnotifications.php
*
* - Upload it to a web host and load mywebhost.com/sendnotifications.php
* in a web browser.
* - Download a local server like WAMP, MAMP or XAMPP. Point the web root
* directory to the folder containing this file, and load
* localhost:8888/sendnotifications.php in a web browser.
*/
// Step 1: Download the Twilio-PHP library from twilio.com/docs/libraries,
// and move it into the folder containing this file.
require ('http://xzenweb.co.uk/reservation/web/twilio-php/Services/Twilio.php');
// Step 2: set our AccountSid and AuthToken from www.twilio.com/user/account
$AccountSid = "";
$AuthToken = "";
// Step 3: instantiate a new Twilio Rest Client
$client = new Services_Twilio($AccountSid, $AuthToken);
// Step 4: make an array of people we know, to send them a message.
// Feel free to change/add your own phone number and name here.
$people = array(
"[phone]" => "Andrew Charlton",
);
// Step 5: Loop over all our friends. $number is a phone number above, and
// $name is the name next to it
foreach ($people as $number => $name) {
$sms = $client->account->messages->sendMessage(
// Step 6: Change the 'From' number below to be a valid Twilio number
// that you've purchased, or the (deprecated) Sandbox number
"YYY-YYY-YYYY",
// the number we are sending to - Any phone number
[phone],
// the sms body
"Hey $name, Monkey Party at 6PM. Bring Bananas!"
);
// Display a confirmation message on the screen
echo "Sent message to $name";
}
}
I've left my account ID and authtoken out of the above.
What is the problem?

Answer 1

so you use require.
According to the documentation and the one of include the require opens a file and evals the code behind it.
what it does in the way you use it, is the following: fetch the file from http://xzenweb.co.uk/reservation/web/twilio-php/Services/Twilio.php (whitch returns nothing at all) and evals id (evals nothing).
This is why your require fails.
If you want to require/include that piece of coe, you should download the sourcecode from http://xzenweb.co.uk/reservation/web/twilio-php/Services/Twilio.php and put it in the environment of your code.
Bit if i understand Twilio right, they are used as an rest webservice.
Accodring to the documentaton http://www.twilio.com/docs/api/rest/sending-messages
you want to download the rest-client-code (like described here https://www.twilio.com/docs/php/install) and then it all come to you ;-)
