PHP implementation to send SMS function code

When developing a Web or mobile app, you'll often encounter the need to send SMS to the user, either because of login reasons, or to send a message. The following PHP code implements the ability to send SMS.
In order to send SMS in any language, an SMS gateway is required. Most SMS will provide an API, here is the use of MSG91 as SMS gateway.

function Send_sms ($mobile, $msg) {$authKey = "xxxxxxxxxxx";d ate_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, the ADD URL encoding here. $message = UrlEncode ($msg); Define route $route = "template";//prepare you post Parameters$postdata = Array (' authkey ' = = $authKey, ' Mobile s ' = = $mobileNumber, ' message ' + $message, ' sender ' and ' $senderId, ' route ' and ' $route '); API url$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);}

where "$authKey =" xxxxxxxxxxx ";" Need you to enter your password, "$senderId =" Ikoonk ";" You are required to enter your SenderID. You need to specify the country code when you enter a mobile number (for example, the United States is 1, India is 91).
Grammar:

<?php$message = "Hello World"; $mobile = "918112998787"; Send_sms ($mobile, $message);? >

2. Send mail using Mandrill
The Mandrill is a powerful SMTP provider. Developers tend to use a third-party SMTP provider to get better delivery of their shipments.
In the following function, you need to put "mandrill.php" in the same folder as the PHP file so that you can use TA to send the message.

function Send_email ($to _email, $subject, $message 1) {require_once ' mandrill.php '; $apikey = ' xxxxxxxxxx ';//specify your API Key Here$mandrill = new Mandrill ($apikey); $message = new StdClass (), $message->html = $message 1; $message->text = $message 1; $message->subject = $subject; $ Message->from_email = "blog@koonk.com";//sender email$message->from_name  = "Koonk";//sender name$message- >to = Array ("e-mail" = $to _email)); $message->track_opens = true; $response = $mandrill->messages->send ($message);} " $apikey = ' xxxxxxxxxx '; Specify your API key here "requires you to specify your API keys (obtained from the Mandrill account).

Grammar:

<?php$to = "abc@example.com"; $subject = "This is a test email"; $message = "Hello world!"; Send_email ($to, $subject, $message);? >

In order to achieve the best results, it is best to follow the Mandrill tutorial to configure DNS.
3. PHP function: Block SQL injection
SQL injection or SQLi common attack site means, use the code below to help you prevent these injections.

function Clean ($input) {    if (Is_array ($input))    {        foreach ($input as $key = = $val)         {            $output [$ Key] = clean ($val);            $output [$key] = $this->clean ($val);        }    }    else    {        $output = (string) $input;        If Magic quotes is on and use strip slashes        if (GET_MAGIC_QUOTES_GPC ())         {            $output = stripslashes ($OUTPU t);        }        $output = Strip_tags ($output);        $output = Htmlentities ($output, ent_quotes, ' UTF-8 ');    } Return the clean text    return $output;

}

NET CLR 3.5.30729) '; $url = ' http://ipinfodb.com/ip_locator.php?ip= '.        UrlEncode ($IP);                $ch = Curl_init (); $curl _opt = Array (curlopt_followlocation = 1, curlopt_header = 0, Curlopt_             Returntransfer = 1, curlopt_useragent = $curlopt _useragent, Curlopt_url = $url, Curlopt_timeout = 1, curlopt_referer = ' http:/'.                $_server[' Http_host '],);                Curl_setopt_array ($ch, $curl _opt);                $content = curl_exec ($ch);        if (!is_null ($curl _info)) {$curl _info = Curl_getinfo ($ch);                } curl_close ($ch); if (Preg_match (' {<li>city: ([^<]*) </li>}i ', $contENT, $regs)) {$city = $regs [1]; } if (Preg_match (' {<li>state/province: ([^<]*) </li>}i ', $content, $regs)) {$state =        $regs [1]; if ($city! = "&& $state! =") {$location = $city. ', ' .          $state;        return $location;         }else{return $default; }            }
