如何在PHP中实现语言包 [英] How to implement language packs in PHP

问题描述

我为我的网站创建了3个语言包：英文，西班牙文和法文。我根据用户选择无法实现它们。我有以下下拉菜单：

 < select onchange ='document.location.href = this.options [this.selectedIndex]。价值;'> 
< option>选择< / option> 
< option value =？lang = eng> US English< / option> 
< option value =？lang = esp>Español< / option> 
< option value =？lang = fra>Français< / option> 
< / select> 
  

如何根据用户选择的内容来包括语言文件在 if语句中，我只是不知道该如何放在条件中。

谢谢。

解决方案

首先，保存用户在用户会话中选择的值。例如：

  switch（$ _ POST ['lang']）{
 case'en' _SESSION ['lang'] ='English';打破; 
 case'sp'：$ _SESSION ['lang'] ='西班牙语';打破; 
 default：$ _SESSION ['lang'] ='English';打破; 
} 

在每个页面请求中，根据相关语言文件夹的语言文件您保存的价值。

例如，这将如何查看文件结构：

• English
  
  
  
  
  • Global.php
  
  
  • Register.php
  
  
  
  
  • 西班牙语
    
    
    
    
    • Global.php
    
    
    • Register.php
    
    
  
  
  
  
  

  然后，只要您需要加载文本文件，请使用：

  
  
  

    function load_text_file（$ filename）{
   include'languages /'。 $ _SESSION ['lang']。 '/'。 $ filename.'php; 
   return $ txt; // $ txt应该是一个数组
  } 
   //...
   
   
   
   $ text = array（）; 
   $ text + = load_text_file（'Global'）; 
   $ text + = load_text_file（'Register'）; 

  
  

  I created 3 language packs for my site: English, Spanish and French. I am just having trouble implementing them based on user selection. I have the following drop down menu:

  <select onchange='document.location.href=this.options[this.selectedIndex].value;'>
    <option>Select</option>
    <option value="?lang=eng">US English</option>
    <option value="?lang=esp">Español</option>
      <option value="?lang=fra">Français</option>
  </select>
  

  How can I include the language files based on what the user selects, I just don't know what to put as the condition in the if statement.

  Thanks.

  解决方案

  At first, save the value that the user selected in the user session. e.g.:

  switch($_POST['lang']) {
      case 'en': $_SESSION['lang'] = 'English'; break;
      case 'sp': $_SESSION['lang'] = 'Spanish'; break;
      default:   $_SESSION['lang'] = 'English'; break;
  }

  On every page request, fetch the language files from the relevant language folder according to the value the you saved.

  For example, this how will look the files structure:

  • English
    • Global.php
    • Register.php
  • Spanish
    • Global.php
    • Register.php

  Then, whenever you need to load a text file, use:

  function load_text_file($filename) {
      include 'languages/' . $_SESSION['lang'] . '/' . $filename.'php';
      return $txt;    // $txt should be an array
  }
  //...
  
  
  $text = array();
  $text += load_text_file('Global');
  $text += load_text_file('Register');
