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)
只有会员才能在此发言
分页: $page1=$page-1; $page2=$page+1; if ($page==1) echo "首页 前页 "; else echo "首页 前页 "; if ($page==$totalpage) echo "后页 尾页 "; else echo "后页 尾页 "; ?> |

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.
