PHP sends AT command, phpat command_PHP tutorial

PHP sends AT command, phpat command

Requirements: Send text messages to the user’s mobile phone, and the message content can be customized

Problem: Without Telecom mode, the free api interface cannot be used to customize the text message content

Solution: Connect to the server through 4G network card, operate the network card through AT commands, and send text messages

After checking, it was found that AT quality transmission requires multiple encoding of the information, and the transmission timed out, but the actual transmission was successful, and the problem has not been completely solved

The code is as follows:

<span>  1</span> <?<span>php
</span><span>  2</span> send_message('8613800138000', '您好, 你正在申请注册服务平台, 您的验证码是: 97431'<span>);
