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;
?>

return $language;
}
function getlanguagename($language) {
$languages = getvailablelanguage();
return $languages[$language];
}
function array_language(){
$array_language = array("en","zh");
return $array_language;
}
function getdefalutlanguage(){
return "zh";
}

4.所包含的language.js
function changelanguage(obj) {

location.href = url;
}
