HomeBackend DevelopmentPHP Tutorial模仿OSO的论坛(一)_php基础

 
    相信每一个到过OSO的人都会对OSO的论坛留下极深的印象,这个论坛无论从那一方面来说都是比较出色的。你想不想你的主页也有这么一个漂亮的论坛呢,其实并不太复杂的,下面我们仅从一些基本的部分来实现对OSO论坛的模仿。
    由于我仅仅是使用这个论坛作为我的留言板,所以我的论坛可以算是OSO论坛的简配。1、在我的论坛中只有在用户登录后才能发言,用户的ID是存在一个叫“cookie_user”的cookie变量中的,2、我的论坛没有子论坛,3、我没有统计一个主题的点击数,4、在OSO论坛中每一个主题前面的表示有没有新贴子的图标我也没设计,5、对于OSO论坛所提供的可选择的主题排列方式以及显示时间段我也没考虑,6、没有会员发贴积分的统计,7、没有版主管理论坛的功能,8、没有贴子编辑的功能。我们将在最后提到如何在我的程序基础上扩充这八项功能。
    首先是一个数据库的设计,事实上一个论坛牵涉到两个数据表,我们暂且将其命名为user、guestbook,在user表中存储的是注册用户的信息。其创建语句如下:
create table my_user(
user_id         char(12)  not null,/*用户名*/
user_password    varchar(8)    not null,/*用户密码*/
PRIMARY KEY (user_id)
)
guestbook中储存的是贴子内容。其创建内容如下:
CREATE TABLE guestbook (
   id bigint DEFAULT '0' NOT NULL auto_increment,/*发言id,自增字段*/
   name varchar(12) NOT NULL,/*主题创建人*/
   type tinyint NOT NULL,/*类型0-回复;1-主贴*/
   theme varchar(50) NULL,/*主题*/
   content blob NOT NULL,/*内容*/
   icon tinyint NOT NULL,/*表情图标*/
   time_open datetime not NULL,/*主题创建时间*/
   time_close datetime not NULL,/*最后回复时间*/
   answer_count int not null,/*回复数*/
   answer_name varchar(12) not null,/*最后回复人*/
   main_id bigint null,/*主贴id*/
   PRIMARY KEY (id)/**/
);
程序包含五个php源代码:分别是connect.inc.php,faq.php,read.php,post.php,reply.php,post_end.php
connect.inc.php:(用来连接数据库)

$dbhostname = "localhost";  
$dbusername = "";  
$dbpassword = "";
$dbName = "";  
MYSQL_CONNECT($dbhostname, $dbusername, $dbpassword) OR DIE("Unable to connect to database");
@mysql_select_db( "$dbName") or die( "Unable to select database");  
?>


faq.php:(用来显示主题列表)

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
