PHP implements function code for sending SMS-PHP Tutorial-php.cn

When developing web or mobile applications, you often encounter the need to send SMS to users, either for login reasons or to send information. The following PHP code implements the function of sending SMS.
In order to send SMS in any language, an SMS gateway is required. Most SMS will provide an API, here MSG91 is used as the SMS gateway.

function send_sms($mobile,$msg) {$authKey = "XXXXXXXXXXX"; date_default_timezone_set("Asia/Kolkata");$date = strftime("%Y-%m-%d %H:%M:%S");//Multiple mobiles numbers separated by comma$mobileNumber = $mobile; //Sender ID,While using route4 sender id should be 6 characters long.$senderId = "IKOONK"; //Your message to send, Add URL encoding here.$message = urlencode($msg); //Define route $route = "template";//Prepare you post parameters$postData = array( 'authkey' => $authKey, 'mobiles' => $mobileNumber, 'message' => $message, 'sender' => $senderId, 'route' => $route); //API URL$url="https://control.msg91.com/sendhttp.php"; // init the resource$ch = curl_init(); curl_setopt_array($ch, array( CURLOPT_URL => $url, CURLOPT_RETURNTRANSFER => true, CURLOPT_POST => true, CURLOPT_POSTFIELDS => $postData //,CURLOPT_FOLLOWLOCATION => true)); //Ignore SSL certificate verificationcurl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); //get response$output = curl_exec($ch);//Print error if anyif(curl_errno($ch)) { echo 'error:' . curl_error($ch); } curl_close($ch); }

Among them, "$authKey = "XXXXXXXXXXX";" requires you to enter your password, and "$senderId = "IKOONK";" requires you to enter your SenderID. When entering a mobile number, you need to specify the country code (for example, 1 for the United States, 91 for India).

2. Use mandrill to send emails
Mandrill is a powerful SMTP provider. Developers tend to use a third-party SMTP provider for better inbox delivery.
In the following function, you need to put "Mandrill.php" in the same folder as a PHP file, so that you can use TA to send emails.

function send_email($to_email,$subject,$message1) {require_once 'Mandrill.php';$apikey = 'XXXXXXXXXX'; //specify your api key here$mandrill = new Mandrill($apikey); $message = new stdClass();$message->html = $message1;$message->text = $message1;$message->subject = $subject;$message->from_email = "blog@koonk.com";//Sender Email$message->from_name = "KOONK";//Sender Name$message->to = array(array("email" => $to_email));$message->track_opens = true; $response = $mandrill->messages->send($message); } “$apikey = 'XXXXXXXXXX'; //specify your api key here”这里需要你指定你的 API 密钥（从 Mandrill 账户中获得）。
