PHP代码解释

Question

我遇到了这段 php 代码，我想知道有没有人知道这段代码的原始来源以及目的和实现。

<?php

    $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);
}

    $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

不确定为什么有人会有一段代码并想知道它来自哪里以及它的用途是什么，但代码来自此文件的服务文件夹中的Twilio.php：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 是一个提供通信服务器的网站，可用于应用程序和网站等内容。您基本上可以使用 Twilio 制作自己的 Skype 版本。我希望这能回答你的问题...
