浅析经典的PHP论坛程序是怎么写成的
浅析经典的PHP论坛程序是如何写成的?
作为一个论坛程序爱好者,趁空闲时间写一下编写论坛的心得。
以自己编写的开源论坛为例,开发重点是在第一步,如何排列出版块,写出这个,接下去就比较顺手了。
版块分为大版块,下面有各个小版块,小版块下面可能还有子版块。为了减少难度,子版块部分忽略不谈。
设计库设计分为2张表
大版块2个字段
id => 主键
bzone =>大版块名称
小版块5个字段
id => 主键
szone => 小版块名称
mark => 小版块说明文字
bid => 大版块ID,对应大版块的主键
ssort => 小版块排序,可以以小版块影响大版块的排序
以这2张表的设计就能够全部搞定论坛版块的功能部分?答案是肯定的
代码实现
$sql_block = "select * from " . C('db_prefix') . "small_block order by ssort desc,bid desc,szone desc";<br> $query_block = mysql_query($sql_block);<br> $data_block = array();<br> $data_big = array();<br> $time1 = date("Y-m-d");<br> $time1 .= " 00:00:00";<br> $time2 = date("Y-m-d");<br> $time2 .= " 23:59:59";<br> while ($arr_block = mysql_fetch_array($query_block)) {<br> $data_block[] = $arr_block;<br> <br> $bsql = "select * from " . C('db_prefix') . "big_block where id=" . $arr_block['bid'];<br> $barr = mysql_fetch_array(mysql_query($bsql));<br> $data_big[$arr_block['bid']] = $barr['bzone'];<br> <br> ${'zhuti' . $arr_block['id']} = mysql_num_rows(mysql_query("select * from " . C('db_prefix') . "talk where parentid=" . $arr_block['id']));<br> $this->assign("zhuti" . $arr_block['id'], ${'zhuti' . $arr_block['id']});<br> <br> ${'tiezi1' . $arr_block['id']} = mysql_num_rows(mysql_query("select * from " . C('db_prefix') . "talk where parentid=" . $arr_block['id']));<br> ${'tiezi2' . $arr_block['id']} = mysql_num_rows(mysql_query("select * from " . C('db_prefix') . "reply where parentid2=" . $arr_block['id']));<br> ${'tiezi' . $arr_block['id']} = ${'tiezi1' . $arr_block['id']} + ${'tiezi2' . $arr_block['id']}; <div class="clear"> </div>

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

When developing an e-commerce website using Thelia, I encountered a tricky problem: MySQL mode is not set properly, causing some features to not function properly. After some exploration, I found a module called TheliaMySQLModesChecker, which is able to automatically fix the MySQL pattern required by Thelia, completely solving my troubles.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.
