How to write a php program to send free sms

PHP program to send sms To send an SMS using PHP, you can use an SMS gateway service, which allows sending SMS messages through an API by connecting to a telecommunications provider’s network.

Yes, it is possible to send SMS messages through PHP using an SMS gateway service. An SMS gateway service allows you to send SMS messages via an API by connecting to a telecommunications provider’s network.

To send an SMS using PHP, you can use the PHP cURL library to make an HTTP request to the SMS gateway service’s API. The specific method of sending the request and the format of the data passed to the gateway service will depend on the SMS gateway service you are using.

It’s important to note that, Some of the SMS gateway services may require an API key or other authentication, you should check with the service provider documentation and include the required credentials in the request.

Also, you might need to handle the responses from the gateway service and handle errors in case of failure.

It’s also important to note that not all countries and mobile carriers are supported by all SMS gateway services, it is best to check with the service provider’s documentation to confirm that your target country and carrier is supported.

Here is a basic PHP program that uses the Twilio API to send a free SMS message:

<?php
// Your Account SID and Auth Token from twilio.com/console
$account_sid = 'YOUR_ACCOUNT_SID';
$auth_token = 'YOUR_AUTH_TOKEN';
// In production, these should be environment variables. E.g.:
// $auth_token = $_ENV["TWILIO_AUTH_TOKEN"]

// A Twilio phone number you purchased at twilio.com/console
$twilio_number = "YOUR_TWILIO_PHONE_NUMBER";

// Where to make a phone call to
$to_number = "YOUR_DESTINATION_PHONE_NUMBER";

// Install the library via Composer or download the .zip file to your project directory.
// This line loads the library
require __DIR__ . '/vendor/autoload.php';

use Twilio\Rest\Client;

$client = new Client($account_sid, $auth_token);
$client->messages->create(
// Where to send a text message (your cell phone?)
$to_number,
array(
'from' => $twilio_number,
'body' => 'This is a test message!'
)
);
?>

Please note that in order to use this code, you will need to sign up for a Twilio account and purchase a phone number, and replace the placeholder values for $account_sid, $auth_token, $twilio_number, and $to_number with your actual Twilio account information and the phone number you want to send the message to.

Also, you will need to install twilio library via composer.

composer require twilio/sdk
