这些 PHP 片段对于 PHP 初学者也非常有帮助，非常容易学习，让我们开始学习吧～

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。 

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);
}

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";
$mobile = "918112998787";
send_sms($mobile,$message);
"4">2. 使用 mandrill 发送邮件 

Mandrill 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。 






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）。 

语法： 






<"abc@example.com";
$subject = "This is a test email";
$message = "Hello World!";
send_email($to,$subject,$message);
"4">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工具。 






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 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;
}




语法： 






<"<script>alert(1)</script>";
$text = clean($text);
echo $text;
"4">4. 检测用户位置

 $url = 'http://ipinfodb.com/ip_locator.php"brush: html;toolbar:false;" data-role="code">
<"4">5. 获取 Web 页面的源代码 

使用下面的函数，可以获取任意 Web 页面的 HTML 代码 








function display_sourcecode($url)
{
$lines = file($url);
$output = "";
foreach ($lines as $line_num => $line) { 
 // loop thru each line and prepend line numbers
 $output.= "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "\n";
}
}




语法： 






<"http://blog.koonk.com";
$source = display_sourcecode($url);
echo $source;
"brush: html;toolbar:false;" data-role="code">
function fb_fan_count($facebook_name)
{
 $data = json_decode(file_get_contents("https://graph.facebook.com/".$facebook_name));
 $likes = $data->likes;
 return $likes;
}




语法： 






<"koonktechnologies";
$count = fb_fan_count($page);
echo $count;
"4">7. 确定任意图片的主导颜色

for ($x=0;$x<imagesx($i);$x++) {
 for ($y=0;$y<imagesy($i);$y++) {
 $rgb = imagecolorat($i,$x,$y);
 $r = ($rgb >> 16) & 0xFF;
 $g = ($rgb >> & 0xFF;
 $b = $rgb & 0xFF;
 $rTotal += $r;
 $gTotal += $g;
 $bTotal += $b;
 $total++;
 }
}
$rAverage = round($rTotal/$total);
$gAverage = round($gTotal/$total);
$bAverage = round($bTotal/$total);
}

 $domain = preg_replace('/^www\./i', '', $domain);
 $domain = explode('/', $domain);
 $domain = trim($domain[0]);
 
 // split the TLD from domain name
 $_domain = explode('.', $domain);
 $lst = count($_domain)-1;
 $ext = $_domain[$lst];
 
 // You find resources and lists 
 // like these on wikipedia:

一口气升级7个大模型SaaS应用，百度智能云：突出一个“开箱即用” - 2024/9/24

这一波大模型产业落地浪潮里，不少企业其实处在 “干瞪眼“的状态。

一种情况是，很多大模型产品看得见却摸不着，在台上一个个遥遥领先——今天Sora技精四座，明天英伟达的机器人又赢得满堂彩，可是到了台下一问：啥时候能用上啊？答曰：遥遥无期。

另一种情况是，企业想用上大模型，却又难免瞻前顾后——既要考虑场景融合，又得兼顾安全性，还要考虑打通现有系统，再加上各种部署成本和繁琐的采购流程……最后只能拂袖：罢了，再等等吧。

                            
                        

                    

                

            

            
稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
