本文实例讲述了php简单实现多语言切换的方法。分享给大家供大家参考，具体如下：

1.主程序代码：

    <?php
    include "lib/function.php";
    ?>
    <script src="js/language.js"></script>
    <?php
    if(isset($_GET["language"])){
      $_SESSION["language"] = $_GET["language"];
    }else{
      $_SESSION["language"] = getDefalutlanguage();
    }
    $language_name = getLanguageName($_SESSION["language"]);
    include "lang/".$language_name.".inc";
    ?>
    <SELECT NAME="language" id="language" onchange="changeLanguage(this)">
    <?php
      $language_array = array_language();
      foreach($language_array as $key => $value){
        if($_SESSION["language"] == $value){
          $selected = "selected = 'selected' ";
        }else{
          $selected = "";
        }
    ?>
    <OPTION VALUE="<?php echo $value;?>" <?php echo $selected;?>><?php echo getLanguageName($value);?></OPTION>;
    <?
      }
    ?>
    </SELECT>
    <?php
      if($_GET["language"] == $value){
          //$selected = "selected = 'selected' ";
        }
    echo "语言：".$_SESSION["language"];
    echo "测试：".$name;
    ?>

     function getLanguageName($language) {
        $languages = getVailableLanguage();
        return $languages[$language];
      }
     function array_language(){
      $array_language = array("en","zh");
