PHP(外文名: Hypertext Preprocessor,中文名:“超文本预处理器”)是一种通用开源脚本语言。语法吸收了C语言、Java和Perl的特点,入门门槛较低,易于学习,使用广泛,主要适用于web开发领域。PHP的文件后缀名为php。
这篇文章主要为大家详细介绍了php面向对象的用户登录身份验证,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
一、代码
conn.php
- <?php
- $conn = new com("adodb.connection");
- $connstr="driver={microsoft access driver (*.mdb)}; dbq=". realpath("data/db_database07_188.mdb");
- $conn->open($connstr);
- ?>

- } class chk //定义密码验证类 { private $name; //定义用户名属性 private $pwd; //定义密码属性
- public function __construct($x,$y) //构造函数,对类的属性初始化 { $this->
