HomeBackend DevelopmentPHP Tutorial了解Joomla 这款来自国外的php网站管理系统_PHP

过去建站一般都自定义开发,这需要技术性很高,而且代码不容易复用,别人也不容易维护,对于CMS来说,实在是没有必要自定义开发,因为CMS的基本功能并不多,很多功能都应该被复用。而joomla是一个完整的CMS,而且它最大特点是扩展性很好。
为什么说joomla扩展性好?你只要到joomla的官方网上找一找组件安装包,你就会看到有上千个组件安装可用,它们都实现各自的功能。如果你的CMS需要增加一个功能,在开发之前可先找一下安装包,这会省去不少功夫。有很多人为joomla开发组件安装包,那也是因为joomla的结构良好与安装包容易开发。joomla默认的功能实现并不多,joomla更像一个程序基层,所有程序都在这个基层上建立,一个一个的小程序就架构出一个功能性很强的网站。就算不使用第三方安装包,把自己常用的功能做成一个组件安装包,也可以很好地复用代码,让开发不再重装。从使用者角度,joomla就像一个桌面系统,它可以安装各种应用软件来丰富网站的功能,让人感觉是那么的好玩。


joomla的结构良好,所以只要熟练joomla,要维护一个joomla站都很容易。自定义写的东西就算再好,维护性始终是个问题,我想没有老板要一套只有一个程序员能看得懂的系统。


对于CMS、BBS等中小型网站架建,自定义开发已经不是主流,新时代要求网站需要更高的开发效率,所以基于完整系统的开发将会占有大部分的市场。目前国内已经越来越多网站开发公司基于现有的开源系统进行二次开发,因为这样意味着产品会有更高的质量与开发效率。


国内也有很多CMS,它们都很好用,不比joomla要差。比如dedecms是全静态,joomla目前还不能做全静态网站,所以访问效率比不上dedecms。虽然dedecms也有模块安装,但不见得有人为dedecms做模块,我没用过dedecms,不过估计是因为dedecms的结构不够通用化或者国内程序员没有为开源写安装包的习惯。反正老外已经架建了那么好的系统,为什么不拿来用一下?


一个WEB程序员的价值,不完全在于他懂很多技术,而在于他是否能够在满足客户需求的情况下更快地完成项目。

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

How does garbage collection work for PHP sessions?How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

How can you trace session activity in PHP?How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AM

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

How can you use a database to store PHP session data?How can you use a database to store PHP session data?Apr 27, 2025 am 12:02 AM

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
