HomeBackend DevelopmentPHP Tutorialthinkphp实现多语言功能(语言包)_PHP

ThinkPHP

1.在Home(你取的项目名)的config.php中添加如下配置

复制代码 代码如下:
return array(
    //'配置项'=>'配置值'
        'LANG_SWITCH_ON'     =>     true,    //开启语言包功能       
        'LANG_AUTO_DETECT'     =>     true, // 自动侦测语言
        'DEFAULT_LANG'         =>     'zh-cn', // 默认语言       
        'LANG_LIST'            =>    'en-us,zh-cn,zh-tw', //必须写可允许的语言列表
        'VAR_LANGUAGE'     => 'l', // 默认语言切换变量
);
?>

2.Home的conf文件夹里添加一个php文件(tag.php),添加如下代码:

复制代码 代码如下:
return array(
    // 添加下面一行定义即可
    'app_begin' => array('CheckLang')
);

3.把Extend/Behavior/CheckLangBehavior.class.php 文件复制到Home/lib/Behavior/中(完整版的thinkphp包才有,没有的话请自行创建)

CheckLangBehavior.class.php代码:

复制代码 代码如下:
defined('THINK_PATH') or exit();
/**
 * 语言检测 并自动加载语言包
 * @category   Extend
 * @package  Extend
 * @subpackage  Behavior
 */
class CheckLangBehavior extends Behavior {
    // 行为参数定义(默认值) 可在项目配置中覆盖
    protected $options   =  array(
            'LANG_SWITCH_ON'        => false,   // 默认关闭语言包功能
            'LANG_AUTO_DETECT'      => true,   // 自动侦测语言 开启多语言功能后有效
            'LANG_LIST'             => 'zh-cn', // 允许切换的语言列表 用逗号分隔
            'VAR_LANGUAGE'          => 'l',        // 默认语言切换变量
        );

    // 行为扩展的执行入口必须是run
    public function run(&$params){
        // 开启静态缓存
        $this->checkLanguage();
    }

    /**
     * 语言检查
     * 检查浏览器支持语言,并自动加载语言包
     * @access private
     * @return void
     */
    private function checkLanguage() {
        // 不开启语言包功能,仅仅加载框架语言文件直接返回
        if (!C('LANG_SWITCH_ON')){
            return;
        }
        $langSet = C('DEFAULT_LANG');
        // 启用了语言包功能
        // 根据是否启用自动侦测设置获取语言选择
        if (C('LANG_AUTO_DETECT')){
            if(isset($_GET[C('VAR_LANGUAGE')])){
                $langSet = $_GET[C('VAR_LANGUAGE')];// url中设置了语言变量
                cookie('think_language',$langSet,3600);
            }elseif(cookie('think_language')){// 获取上次用户的选择
                $langSet = cookie('think_language');
            }elseif(isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])){// 自动侦测浏览器语言
                preg_match('/^([a-z\d\-]+)/i', $_SERVER['HTTP_ACCEPT_LANGUAGE'], $matches);
                $langSet = $matches[1];
                cookie('think_language',$langSet,3600);
            }
            if(false === stripos(C('LANG_LIST'),$langSet)) { // 非法语言参数
                $langSet = C('DEFAULT_LANG');
            }
        }
        // 定义当前语言
        define('LANG_SET',strtolower($langSet));

        $group = '';
        $path    =   (defined('GROUP_NAME') && C('APP_GROUP_MODE')==1) ? BASE_LIB_PATH.'Lang/'.LANG_SET.'/' : LANG_PATH.LANG_SET.'/';
        // 读取项目公共语言包
        if(is_file(LANG_PATH.LANG_SET.'/common.php'))
            L(include LANG_PATH.LANG_SET.'/common.php');    
        // 读取分组公共语言包
        if(defined('GROUP_NAME')){
            if(C('APP_GROUP_MODE')==1){ // 独立分组
                $file = $path.'common.php';
            }else{ // 普通分组
                $file = $path.GROUP_NAME.'.php';
                $group = GROUP_NAME.C('TMPL_FILE_DEPR');
            }
            if(is_file($file))
                L(include $file);
        }
        // 读取当前模块语言包
        if (is_file($path.$group.strtolower(MODULE_NAME).'.php'))
            L(include $path.$group.strtolower(MODULE_NAME).'.php');
    }
}

4.在Home里的lang文件夹下创建3个语言文件夹。分别是zh-cn  en-us  zh-tw,

在这三个文件夹里各创建一个common.php文件,如图:

在common.php 里对应写上
复制代码 代码如下:
return array(
        'welcome'=>'Welcome to use thinkphp',
);
?>

复制代码 代码如下:
return array(
    'welcome'=>'欢迎使用ThinkPHP',
);
?>

复制代码 代码如下:
return array(
    'welcome'=>'歡迎使用ThinkPHP',
);
?>

5.在tpl/Index/文件夹下创建视图 index.html

复制代码 代码如下:


 


 
  ThinkPHP示例:多语言
 
 
 

切换语言:简体中文 | 繁体中文 | 英文

 
{$Think.lang.welcome}


 

大功告成!

后台语言要进行语言切换的话, 在每句话之前加L,如:

复制代码 代码如下:
public function index(){
print  L('add_user_error');  //add_user_error只是语言变量,具体的语言要到语言包里写
$this->display();
}

这一点我觉得cakephp做的就比较好,不需要给每句话都给予一个变量。

Beyond the Hype: Assessing PHP's Role TodayBeyond the Hype: Assessing PHP's Role TodayApr 12, 2025 am 12:17 AM

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

What are Weak References in PHP and when are they useful?What are Weak References in PHP and when are they useful?Apr 12, 2025 am 12:13 AM

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP vs. Python: Understanding the DifferencesPHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AM

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP: Is It Dying or Simply Adapting?PHP: Is It Dying or Simply Adapting?Apr 11, 2025 am 12:13 AM

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The Future of PHP: Adaptations and InnovationsThe Future of PHP: Adaptations and InnovationsApr 11, 2025 am 12:01 AM

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software

SecLists

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.
