How to implement multi-language in PHP

php realizes multi-language functions:

Recommendation: php5 download

In Home (the project name you chose) Add the following configuration to config.php

'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  
);  
?>

Copy after login

Add a php file (tag.php) to the conf folder of Home and add the following code:

return array(  
    // 添加下面一行定义即可  
    'app_begin' => array('CheckLang')  
);

Copy after login

Put Extend/Behavior/CheckLangBehavior.class. Copy the php file to Home/lib/Behavior/ (only the full version of thinkphp package is available, if not, please create it yourself)

CheckLangBehavior.class.php code:

 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');  
    }  
}

Copy after login

in Home Create 3 language folders under the lang folder. They are zh-cn en-us zh-tw,

Create a common.php file in each of these three folders, as shown in the picture:

Write the corresponding in common.php

'Welcome to use thinkphp',  
);  
?>

Copy after login

'欢迎使用ThinkPHP',  
);  
?>

Copy after login

'歡迎使用ThinkPHP',  
);  
?>

Copy after login

Create the view index.html in the tpl/Index/ folder

  
  
   
    
  ThinkPHP示例：多语言  
 
  
   
   
切换语言：简体中文 | 繁体中文 | 英文  
 {$Think.lang.welcome}
