Question

I have an account in a website by which I can send sms to mobile phones. In order to do that at first I need to log in using my id and password and then a page shows up where I put the recipient’s mobile number and then my message and finally hit the button to send the message.

Now one of my friends told me that I can send sms from my own application through this website using PHP Curl function. I didn’t have any prior idea about CURL function so I googled it but I couldn’t figure out how to do this. I have checked the HTML code of the login page and the page from where I can send the sms of that website and I am posting it below.

Would you please kindly show me how to send sms using CURL function or any other way.. through this website..

Thanks in Advance 🙂

Answer 1

This is a solution using Twilio.

First of all you have to download the twilio library for PHP:
https://github.com/twilio/twilio-php/downloads

Then copy the Services folder in your Server and take in mind the location.

Now you have to create a simple program like the one below, (this is an example an easy php sms sender):

<?php //lets say that the name of this php is smsSender.php

$contactname = $_POST['name'];
$contactphone = $_POST['mobile_no'];

$message = $_POST['message'];


require 'Services/Twilio.php';//<<<<<<<<<HERE! make sure the path is ok.

$AccountSid = "AXXXXXX"; // this numbers you can find it in your twilio dashboard
$AuthToken = "TXXXXXXXXX";// also this number .

$client = new Services_Twilio($AccountSid, $AuthToken);

$people = array(
//"4566789903" => "Curious George",
$contactphone => $contactname,
);

foreach ($people as $number => $name) {

$sms = $client->account->sms_messages->create("7035960031",$number,
$message);

echo "Sent message to $name";

}
?>

So you will need to change in your forms the action like this:

<form name="form" action="smsSender.php" method="POST">

Note: if you are using a trial account, you will be only able to send to verified numbers in your account, but if you register a phone number (1USD/month) then you can send to any number and without the sandbox message).

IMPORTANT: Curl library must be installed in the php server, if you are using your own server, lets say in UBUNTU, this command will install those libraries:
sudo apt-get install curl libcurl3 libcurl3-dev php5-curl
