本文介绍了:必须收藏的23个PHP实用代码片段,希望对您有用。如果有疑问,可以联系我们。
PHP实战在编写代码的时候有个神奇的工具总是好的!下面这里收集了 40+ PHP 代码片段,可以赞助你开发 PHP 项目.
这些 PHP 片段对于 PHP 初学者也非常有赞助,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.
PHP实战 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($ch); }
PHP实战其中“$authKey = "XXXXXXXXXXX";”需要你输入你的暗码,“$senderId = "IKOONK";”需要你输入你的 SenderID.当输入移动号码的时候需要指定国家代码 (比如,美国是 1,印度是 91 ).
语法:
PHP实战2. 使用 mandrill 发送邮件
Mandrill 是一款强大的 SMTP 提供器.开发者倾向于使用一个第三方 SMTP provider 来获取更好的收件交付.
下面的函数中,你需要把 “Mandrill.PHP” 放在同一个文件夹,作为 PHP 文件,这样就可以使用TA来发送邮件.
PHP实战 function send_email($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); }
PHP实战$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:
PHP实战 <?PHP $to = "abc@example.com"; $subject = "This is a test email"; $message = "Hello World!"; send_email($to,$message); ?>
PHP实战为了达到最好的效果,最好依照 Mandrill 的教程去配置 DNS.
PHP实战3. PHP 函数:阻止 sql 注入
sql 注入或者 sqli 常见的攻击网站的手段,使用下面的代码可以赞助你防止这些工具.
PHP实战
function clean($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;
}
