其中“$authKey = "XXXXXXXXXXX";”需要你输入你的密码,“$senderId = "IKOONK";”需要你输入你的 SenderID。当输入移动号码的时候需要指定国家代码 (比如,美国是 1,印度是 91 )。 语法:
- 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 => $postData
- //,CURLOPT_FOLLOWLOCATION => true
- ));
- //Ignore SSL certificate verification
- curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
- curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
- //get response
- $output = curl_exec($ch);
- //Print error if any
- if(curl_errno($ch))
- {
- echo 'error:' . curl_error($ch);
- }
- curl_close($ch);
- }
2. 使用 mandrill 发送邮件
- <?php
- $message = "Hello World";
- $mobile = "918112998787";
- send_sms($mobile,$message);
- ?>
$apikey = 'XXXXXXXXXX'; //specify your api key here”这里需要你指定你的 API 密钥(从 Mandrill 账户中获得)。 语法:
- function send_email($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 = "[email protected]";//Sender Email
- $message->from_name = "KOONK";//Sender Name
- $message->to = array(array("email" => $to_email));
- $message->track_opens = true;
- $response = $mandrill->messages->send($message);
- }
为了达到最好的效果,最好按照 Mandrill 的教程去配置 DNS。 3. PHP 函数:阻止 SQL 注入
- <?php
- $to = "[email protected]";
- $subject = "This is a test email";
- $message = "Hello World!";
- send_email($to,$subject,$message);
- ?>
语法:

- }
- }
- else
- {
- $output = (string) $input;
- // if magic quotes is on then use strip slashes
- if (get_magic_quotes_gpc())
- {
- $output = stripslashes($output);
- }
- // $output = strip_tags($output);
- $output = htmlentities($output, ENT_QUOTES, 'UTF-8');
- }
- // return the clean text
- return $output;

- $url = 'http://ipinfodb.com/ip_locator.php?ip=' . urlencode($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;
- }
- }
