【原】实验室签到PHP版本-优快云博客

本文介绍了一个基于PHP的实验室自动签到系统实现方案。该系统通过网页表单收集学生的学号和密码，并将这些信息存入数据库。随后利用CURL发起HTTP请求实现自动化的远程签到或签离操作。

表单

<html>
<body>
<h1>实验室自动签到测试</h1>
<h2>输入学号和登录密码（建议自己改过密码后再来录入您的数据）</h2>
<form action="mydb.php" method="post">
学号: <input type="text" name="studentid" />
登录密码: <input type="text" name="pw" />
<input type="submit" value="OK" />
</form>
