Twillio Php api

There
I’m Using Twillio Example api

// Step 1: Get the Twilio-PHP library from twilio.com/docs/libraries/php, 
// and move it into the folder containing this sendnotifications.php file.
require "Services/Twilio.php";

// Step 2: set our AccountSid and AuthToken from https://twilio.com/console
$AccountSid = "ACea465f2e60ae87332cf47adb0e4aad64";
$AuthToken = "your_auth_token";

// 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(
    "+15558675309" => "Curious George",
    "+15558675308" => "Boots",
    "+15558675307" => "Virgil",
);

// 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
        "+15017250604", 

        // the number we are sending to - Any phone number
        $number,

        // the sms body
        "Hey $name, Monkey Party at 6PM. Bring Bananas!"
    );

    // Display a confirmation message on the screen
    echo "Sent message to $name";
}

and here is my code

// Step 1: Get the Twilio-PHP library from twilio.com/docs/libraries/php, 
// and move it into the folder containing this sendnotifications.php file.
require "Services/Twilio.php";

// Step 2: set our AccountSid and AuthToken from https://twilio.com/console
$AccountSid = "accountsid";
$AuthToken = "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(
    "my-number-goes-here" => "Ali M. Ayad",

);

// 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
        "+13862593325", 

        // the number we are sending to - Any phone number
        $number,

        // the sms body
        "Hey Ali This is test message form the api"
    );
    // Display a confirmation message on the screen
    echo "Sent message to $name";
}
