PHP - realize automatic switching of multiple languages
I believe that many students have browsed many websites with multi-language switching, and they feel that they are very good. Today, the editor has brought you an article about using PHP to perform automatic multi-language switching. introduce. I believe many students don’t know that PHP can also switch languages, so let us take a look at how PHP is implemented!
1. Add the following configuration in config.php of Home (the project name you chose)
<?php
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. 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')
);3. Copy the Extend/Behavior/CheckLangBehavior.class.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:
<?php
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. 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 figure:
In common.php, write<?php
return array(
'welcome'=>'Welcome to use thinkphp',
);
?><?php
return array(
'welcome'=>'欢迎使用ThinkPHP',
);<?php
return array(
'welcome'=>'歡迎使用ThinkPHP',
);
?>5. Create the view index.html# in the tpl/Index/ folder ##<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>ThinkPHP示例：多语言</title>
</head>
<body>
<div class="main">
<div>切换语言：<a href="?l=zh-cn">简体中文</a> | <a href="?l=zh-tw">繁体中文</a> | <a href="?l=en-us">英文</a></div>
<div class="result">{$Think.lang.welcome}</div>
</div>
</body>
</html>
Done!

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
