How to implement SMS notification in PHP? - php

Question

I tried implementing curl in my code. But there is no error showing in the code editor but when the code is execute, I receive no message or feedback from the API. Is there something with my code? I also suspected that the url is wrong coded so it cannot be executed as an working url.
$token = "Yfkrf59TrbzxJHtbfn55P9OcyKMS7jq6";
$message = "Your Order Is Delivered";
$contact = $_GET['contactno'];
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://terminal.adasms.com/api/v1/send?_token=".$token."&phone=".$contact."&message=".$message."",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET"
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
I tried to build my url with php variable but nothing worked.
<?php
session_start();
if (isset($_GET['id'])) {
include "dbh.inc.php";
$id = $_GET['id'];
$current = $_SESSION['u_id'];
$newstatus = $_GET['orderstatus'];
if ($newstatus == "Pending")
{
$sql = "UPDATE orders SET orderstatus = 'Accepted' WHERE orderid = '$id';";
mysqli_query($con, $sql);
header("Location: ../currentorder.php");
}
else if ($newstatus == "Accepted")
{
$sql = "UPDATE orders SET orderstatus = 'In Delivery' WHERE orderid = '$id';";
mysqli_query($con, $sql);
header("Location: ../currentorder.php");
}
else if ($newstatus == "In Delivery")
{
$sql = "UPDATE orders SET orderstatus = 'Delivered' WHERE orderid = '$id';";
mysqli_query($con, $sql);
$token = "Yfkrf59TrbzxJHtbfn55P9OcyKMS7jq6";
$message = "Your Order Is Delivered";
$contact = $_GET['contactno'];
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://terminal.adasms.com/api/v1/send?_token=".$token."&phone=".$contact."&message=".$message."",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET"
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
header("Location: ../currentorder.php");
}
else{
header("Location: ../currentorder.php");
}
}
