Way2SMS Gateway

To send SMS free of charge is as easy as sending mail with PHP.
Way2SMS provides API to us for getting success in this task.

Following are the steps to get started with Sending SMS from your website:

Step:1

Sign Up / Login into way2sms.com

Step:2

Get Login ID and password from it. Prepare your PHP / HTML file for getting Mobile number and message to send end users. 

Step:3

 Put in the form's action as "my_sms.php"

Step:4

 Take a new file and save as my_sms.php and write below code:

in sendWay2SMS(), put your Login ID and Password.

Step:5

Make a new file as "way2sms-api.php" and put following code into it:

<?php

function sendWay2SMS($uid, $pwd, $phone, $msg)
{
  $curl = curl_init();
  $timeout = 30;
  $result = array();

  $uid = urlencode($uid);
  $pwd = urlencode($pwd);

  // Go where the server takes you :P
  curl_setopt($curl, CURLOPT_URL, "http://way2sms.com");
  curl_setopt($curl, CURLOPT_HEADER, true);
  curl_setopt($curl, CURLOPT_FOLLOWLOCATION, false);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
  $a = curl_exec($curl);
  if(preg_match('#Location: (.*)#', $a, $r))
    $way2sms = trim($r[1]);

  // Setup for login
  curl_setopt($curl, CURLOPT_URL, $way2sms."Login1.action");
  curl_setopt($curl, CURLOPT_POST, 1);
  curl_setopt($curl, CURLOPT_POSTFIELDS, "username=".$uid."&password=".$pwd."&button=Login");
  curl_setopt($curl, CURLOPT_COOKIESESSION, 1);
  curl_setopt($curl, CURLOPT_COOKIEFILE, "cookie_way2sms");
  curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
  curl_setopt($curl, CURLOPT_MAXREDIRS, 20);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.5) Gecko/2008120122 Firefox/3.0.5");
  curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $timeout);
  curl_setopt($curl, CURLOPT_REFERER, $way2sms);
  $text = curl_exec($curl);

  // Check if any error occured
  if (curl_errno($curl))
    return "access error : ". curl_error($curl);

  // Check for proper login
  $pos = stripos(curl_getinfo($curl, CURLINFO_EFFECTIVE_URL), "ebrdg.action");
  if ($pos === "FALSE" || $pos == 0 || $pos == "")
   return "invalid login";

  // Check the message
  if (trim($msg) == "" || strlen($msg) == 0)
    return "invalid message";

  // Take only the first 140 characters of the message
  $msg = urlencode(substr($msg, 0, 140));
  // Store the numbers from the string to an array
  $pharr = explode(",", $phone);

  // Set the home page from where we can send message
  $refurl = curl_getinfo($curl, CURLINFO_EFFECTIVE_URL);
  $newurl = str_replace("ebrdg.action?id=", "main.action?section=s&Token=", $refurl);
  curl_setopt($curl, CURLOPT_URL, $newurl);

  // Extract the token from the URL
  $jstoken = substr($newurl, 50, -41);
  //Go to the homepage
  $text = curl_exec($curl);

  // Send SMS to each number
  foreach ($pharr as $p)
  {
    // Check the mobile number
    if (strlen($p) != 10 || !is_numeric($p) || strpos($p, ".") != false)
    {
      $result[] = array('phone' => $p, 'msg' => urldecode($msg), 'result' => "invalid number");
      continue;
    }
    $p = urlencode($p);

    // Setup to send SMS
    curl_setopt($curl, CURLOPT_URL, $way2sms.'smstoss.action');
    curl_setopt($curl, CURLOPT_REFERER, curl_getinfo($curl, CURLINFO_EFFECTIVE_URL));
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, "ssaction=ss&Token=".$jstoken."&mobile=".$p."&message=".$msg."&button=Login");
    $contents = curl_exec($curl);

    //Check Message Status
    $pos = strpos($contents, 'Message has been submitted successfully');
    $res = ($pos !== false) ? true : false;
    $result[] = array('phone' => $p, 'msg' => urldecode($msg), 'result' => $res);
  }

  // Logout
  curl_setopt($curl, CURLOPT_URL, $way2sms."LogOut");
  curl_setopt($curl, CURLOPT_REFERER, $refurl);
  $text = curl_exec($curl);

  curl_close($curl);
  return $result;
}

?>
