A PHP forum program that imitates oso (Part 1) Page 1/2_PHP Tutorial
我经常使用oso的论坛,个人感觉挺好的,因此模仿oso的界面编了一个程序,与大家共享。
程序由三部分组成,即显示主题信息,显示论坛信息,增加论坛信息,主题与论坛内容采用主从表关系。
表结构如下:
drop table fr_t_forumtitle;
create table fr_t_forumtitle(
id integer,
state varchar(1),
readcount integer,
replycount integer,
title varchar(100),
createman varchar(20),
replyman varchar(20),
replytime datetime);
drop table fr_t_forumcontent;
create table fr_t_forumcontent(
id integer,
replyman varchar(20),
replytime datetime,
replyemail varchar(100),
replyhttp varchar(100),
replyface smallint,
content text);
drop table fr_t_parameter;
create table fr_t_parameter(
code varchar(10),
name varchar(40),
content varchar(10));
insert into fr_t_parameter(code,name,content) values('pageline','分页数','20'); /* 调整该参数可以修改每页行数 */
程序1:mainforum.php
include ("c:mydbheader.inc");
?>
当前位置:主页——论坛 |   | 论坛搜索 |   |
$dbh = mysql_connect('localhost:3306','root','');
mysql_select_db('test');
$res=mysql_query("SELECT content FROM fr_t_parameter where code = 'pageline'",$dbh);
$row=mysql_fetch_array($res);
global $pageline;
$pageline = $row["content"];
if (empty($pageline)) {
$res=mysql_query("insert into fr_t_parameter(code,name,content) values('pageline','分页数','20')",$dbh);
$row=mysql_fetch_array($res);
$pageline = 20;
}
$res=mysql_query("SELECT COUNT(*) AS rcnt FROM fr_t_forumtitle",$dbh);
$row=mysql_fetch_array($res);
$rcount = $row["rcnt"];
$res=mysql_query("SELECT COUNT(*) AS rcnt_con FROM fr_t_forumcontent",$dbh);
$row=mysql_fetch_array($res);
$rcon_count = $row["rcnt_con"];
print '
'; |
$pages=ceil($rcount / $pageline); //$pages变量现在包含所需的页数
if (empty($offset)) {
$offset=1;
$curline = 0;
} else
$curline = ($offset - 1) * $pageline;
//打印表头
print '
';
if ($offset 1) { //如果偏移量是0,不显示前一页的链接 $newoffset=$offset - 1; print "前一页"; } else { print "前一页"; print " "; } //计算总共需要的页数 $pages=ceil($rcount/$pageline); //$pages变量现在包含所需的页数 |

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
