PHP实现在线发短信，需要借助第三方API，以下代码就是调用了TextMagic API来实现发送短信的功能：
<?php
//引入TextMagic PHP库文件
require('textmagic-sms-api-php/TextMagicAPI.php');
$username = 'myusername';
$password = 'mypassword';
$router = new TextMagicAPI(array(
'username' => $username,
'password' => $password
));
//发送一条信息到'222-345-5678'
$result = $router->send('Wake up!', array(2223455678), true);
//结果（官方资料）: Array ( [messages] => Array ( [19896128] => 9991234567 ) [sent_text] => Wake up! [parts_count] => 1 )
?>若没有TextMagic API类库的可在此下载：去下载
