本文实例分析了CodeIgniter多语言实现方法。分享给大家供大家参考,具体如下:
CI应用目录下有一个language语言包目录,用来配置多种不同的语言。语言的配置位于config文件中,配置格式如下:
代码如下:
$config['language'] = 'english';
定义语言文件
language下有个空的english目录,即上面定义的系统默认语言目录,系统会从该目录加载语言包文件。如果要定义不同的语言包,如zh_cn,则创建zh_cn目录并配置相应语言包文件即可。需要注意的是,语言文件的后缀必须为_lang.php,语言翻译通过数组的键值对来实现,为防止出现重复的键名,可以为键名增加统一的前缀。
配置的方式可参考下面:
$lang['menu_system_title'] = '系统设置'; $lang['menu_system_user_admin'] = '用户管理'; $lang['menu_system_user_list'] = '用户列表'; $lang['menu_system_user_detail'] = '用户详情'; $lang['menu_system_setting'] = '配置管理'; /* End of file user_menu_lang.php */ /* Location: ./system/language/zh_tw/user_menu_lang.php */
语言包的使用
使用语言包之前需要先加载语言包,加载和使用方式如下:
//加载方式一,加载时不需要传入_lang $this->load->language(array('user_menu', 'user_message')); //加载方式二 $this->lang->load('user_menu'); //使用方式一 echo $this->lang->line('language_key'); //使用方式二(需先加载language帮助函数) $this->load->helper('language'); echo lang('menu_system_title');
可以说语言包的使用相当简单,前不久也做了个台湾版的系统,顺便说下CI中的语言包的使用及需要注意的问题。
1、$config['language'] 直接配置成 zh_cn 会怎么样?
系统中有一些默认的语言包位于system/language/english目录下,当使用系统中提供的一些类报错时会加载对应的语言包。此时系统会先到language/zh_cn目录下去查找,然后去system/language/zh_cn目录下查找,都找不到就提示找不到语言包的错误。所以若更改了language配置,最好拷贝system/language/english下的文件到对应的语言目录下。
这里看起来有点奇怪,为什么不是这种思维:先到language/zh_cn目录下去找,找不到就到system/language/english目录下去找。叫english可能不合适,应该称呼为系统默认的语言包。
2、是否需要使用语言包?
在某个系统中发现这样子的情况, 有些错误提示用的语言包,有些直接用的中文,可能因为多人开发的原因,键的命名也不太规范,经常需要去对比对应的语言文件,导致程序阅读起来相对麻烦,而中文的则没该问题,个人在系统中使用语言包也觉得有点麻烦。所以,不需要考虑多语言的程序尽量还是不要使用语言包的好。
3、如何自动检测语言包?
通常情况下可以根据浏览器的语言类型来判断,PHP中的$_SERVER['HTTP_ACCEPT_LANGUAGE']可以获取到该值,然后根据字符串分隔或者正则匹配等方式即可获取到客户端浏览器默认语言类型。获取到之后通过
代码如下:
$this->config->set_item('language', 'zh_cn');
设置即可。关于是否确实使用了语言包,可以重写lang函数,带^_^即为使用了语言包,参考如下:
function lang($line, $param = array()) { $CI =& get_instance(); $line = $CI->lang->line($line); if(is_array($param) && count($param) > 0) { array_unshift($param, $line); $line = call_user_func_array('sprintf', $param); } return '^_^'.$line; }
很多情况下多语言的实现都是通过数组的形式来实现,还有一些是.mo的格式,l18n多语言的实现方式,php中需要php_gettext扩展支持,详情可查阅相关资料。

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
