1. 发送 SMS
在开发 Web 或者移动应用的时候，经常会遇到需要发送 SMS 给用户，或者因为登录原因，或者是为了发送信息。下面的 PHP 代码就实现了发送 SMS 的功能。
为了使用任何的语言发送 SMS，需要一个 SMS gateway。大部分的 SMS 会提供一个 API，这里是使用 MSG91 作为 SMS gateway。
send_sms(, = "XXXXXXXXXXX""Asia/Kolkata" = ("%Y-%m-%d %H:%M:%S"
= <span style="color: #008000">//<span style="color: #008000">Sender ID,While using route4 sender id should be 6 characters long.
<span style="color: #800080">$senderId = "IKOONK"<span style="color: #000000">; <span style="color: #008000">//<span style="color: #008000">Your message to send,Add URL encoding here.
<span style="color: #800080">$message = <span style="color: #008080">urlencode(<span style="color: #800080">$msg<span style="color: #000000">); <span style="color: #008000">//<span style="color: #008000">Define route
<span style="color: #800080">$route = "template"<span style="color: #000000">;
<span style="color: #008000">//<span style="color: #008000">Prepare you post parameters
<span style="color: #800080">$postData = <span style="color: #0000ff">array<span style="color: #000000">(
'authkey' => <span style="color: #800080">$authKey,'mobiles' => <span style="color: #800080">$mobileNumber,'message' => <span style="color: #800080">$message,'sender' => <span style="color: #800080">$senderId,'route' => <span style="color: #800080">$route<span style="color: #000000">
);
<span style="color: #800080">$senderId = "IKOONK"<span style="color: #000000">; <span style="color: #008000">//<span style="color: #008000">Your message to send,Add URL encoding here.

<span style="color: #800080">$postData = <span style="color: #0000ff">array<span style="color: #000000">(

<span style="color: #008000">//<span style="color: #008000">API URL

<span style="color: #008000">//<span style="color: #008000">get response
<span style="color: #800080">$output = curl_exec(<span style="color: #800080">$ch<span style="color: #000000">);

}
curl_close(<span style="color: #800080">$ch<span style="color: #000000">);
}
其中“$authKey = "XXXXXXXXXXX";”需要你输入你的密码，“$senderId = "IKOONK";”需要你输入你的 SenderID。当输入移动号码的时候需要指定国家代码 (比如，美国是 1，印度是 91 )。
语法：
= "Hello World" = "918112998787",?>
2. 使用 mandrill 发送邮件
Mandril 是一款强大的 SMTP 提供器。开发者倾向于使用一个第三方 SMTP provider 来获取更好的收件交付。
下面的函数中，你需要把 “Mandrill.php” 放在同一个文件夹，作为 PHP 文件，这样就可以使用TA来发送邮件。
send_email(,, 'Mandrill.php' = 'XXXXXXXXXX';
= Mandrill(<span style="color: #800080">$message = <span style="color: #0000ff">new<span style="color: #000000"> stdClass();
<span style="color: #800080">$message->html = <span style="color: #800080">$message1<span style="color: #000000">;
<span style="color: #800080">$message->text = <span style="color: #800080">$message1<span style="color: #000000">;
<span style="color: #800080">$message->subject = <span style="color: #800080">$subject<span style="color: #000000">;
<span style="color: #800080">$message->from_email = "blog@koonk.com";<span style="color: #008000">//<span style="color: #008000">Sender Email
<span style="color: #800080">$message->from_name = "KOONK";<span style="color: #008000">//<span style="color: #008000">Sender Name
<span style="color: #800080">$message->to = <span style="color: #0000ff">array(<span style="color: #0000ff">array("email" => <span style="color: #800080">$to_email<span style="color: #000000">));
<span style="color: #800080">$message->track_opens = <span style="color: #0000ff">true<span style="color: #000000">;
<span style="color: #800080">$message->html = <span style="color: #800080">$message1<span style="color: #000000">;
<span style="color: #800080">$message->text = <span style="color: #800080">$message1<span style="color: #000000">;
<span style="color: #800080">$message->subject = <span style="color: #800080">$subject<span style="color: #000000">;
<span style="color: #800080">$message->from_email = "blog@koonk.com";<span style="color: #008000">//<span style="color: #008000">Sender Email
<span style="color: #800080">$message->from_name = "KOONK";<span style="color: #008000">//<span style="color: #008000">Sender Name
<span style="color: #800080">$message->to = <span style="color: #0000ff">array(<span style="color: #0000ff">array("email" => <span style="color: #800080">$to_email<span style="color: #000000">));
<span style="color: #800080">$message->track_opens = <span style="color: #0000ff">true<span style="color: #000000">;
<span style="color: #800080">$response = <span style="color: #800080">$mandrill->messages->send(<span style="color: #800080">$message<span style="color: #000000">);
}
“$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：
= "abc@example.com" = "This is a test email" = "Hello World!",?>
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
SQL 注入或者 SQLi 常见的攻击网站的手段，使用下面的代码可以帮助你防止这些注入。
clean( (( ( => [] = clean(clean($val);
= ()
( = (
= (,ENT_QUOTES,'UTF-8'
语法：
= "" = clean( ?>
4. 检测用户位置
使用下面的函数，可以检测用户是在哪个城市访问你的网站。
detect_city(
