PHP代码说明

Question

我遇到了这段php代码，我想知道有没有人知道这个代码的原始来源和目的以及实现。

<?php 

require "twilio/Services/Twilio.php"; 

function sqlconnect() 
{ 
    $dbhost="localhost";   //database host 
    $dbuser="root";   //database username 
    $dbpassword="xxxxxx";  //database password  
    $dbname="xxxxx";   //database name 
    $db = mysql_connect($dbhost,$dbuser,$dbpassword) or die("Couldn't connect to the database."); 
    mysql_select_db($dbname) or die("Couldn't select the database"); 
    return($db); 
} 

function sendsms($msg) { 
    $AccountSid = "xxxxx"; //twilio settings 
    $AuthToken = "xxxx"; //twilio settings 
    $client = new Services_Twilio($AccountSid, $AuthToken); 
// $sms = $client->account->sms_messages->create("xxxx", "+xxxx", $msg); //twilio settings 
    $sms = $client->account->sms_messages->create("6xxxx", "+xxxx", $msg); //twilio settings 
    echo"\n\nSending SMS\n\n"; 
} 

$queue = array(); 

//////// setup our named pipe ////////

               sendsms("New device detected on home network. MAC address $mac"); 
             } else {

不知道为什么会有人有一段代码，并想知道它是从哪里来的，而且它的目的是什么，但代码是从Twilio.php在这个文件中的服务文件夹：https://github.com/twilio/twilio-php/archive/master.zip

这是一个Twilio PHP库，允许您在PHP中使用Twilio服务。 Twilio是一个提供可用于应用程序和网站等通信服务器的网站。你基本上可以用Twilio制作你自己的Skype版本。我希望这可以回答你的问题...
