使用GSM调制解调器在PHP中发送短信

Question

我是新手PHP开发者，目前参与了一个需要通过短信通知客户的项目。我知道有一些可以使用的短信服务，但是我的老板想尝试使用GSM调制解调器。

请问是否可以使用GSM调制解调器发送短信？如果有教程将会非常有帮助。

谢谢。

@Pekka웃 这并不是真的。PHP中有很多可用于打开串口的类，这正是此任务所需的。 - Brad

可能是为短信实现GSM调制解调器的重复问题。 - Brad

@Brad 感谢您的回复。但是发送短信只是为了在分配新工作时通知组织的服务工程师，每天最多会产生约50条短信。这就是他想尝试使用GSM调制解调器的原因。我尝试寻找一些教程，但大多数都对COM端口等感到困惑...任何帮助将不胜感激。 - Karthik Nk

@KarthikNk 我不知道有没有现成的代码可以发送短信...不同的设备使用不同的命令，但许多命令是标准化的。请查看您的GSM调制解调器附带的文档。您需要查找“AT命令参考”文档。 - Brad

you can use following code, it works on my gsm modem. its zyxel

<?php

//SMS via GSM Modem - A PHP class to send SMS messages via a GSM modem attached to the computers serial port.

//Windows only (tested on XP with PHP 5.2.6)
//Tested with the EZ863 (Telit GE863) GSM modementer code here
//Requires that PHP has permission to access "COM" system device, and system "mode" command

error_reporting(E_ALL);

//Example

$gsm_send_sms = new gsm_send_sms();
$gsm_send_sms->debug = false;
$gsm_send_sms->port = 'COM6';

$gsm_send_sms->init();

$status = $gsm_send_sms->send('09360403533', 'testing 123');

    echo "Message sent\n";
} else {

$gsm_send_sms->close();
