php实现获取及设置用户访问页面语言类_php技巧
本文实例讲述了php实现获取及设置用户访问页面语言类,分享给大家供大家参考。具体分析如下:
该实例User Language Class 获取/设置用户访问的页面语言,如果用户没有设置访问语言,则读取Accept-Language。根据用户选择的语言显示对应的页面(英文,简体中文,繁体中文)
UserLang.class.php类文件如下:
<?php /** User Language Class 获取/设置用户访问的页面语言,如果用户没有设置访问语言,则读取Accept-Language * Date: 2014-05-26 * Author: fdipzone * Ver: 1.0 * * Func: * public get 获取用户访问语言 * public set 设置用户访问语言 * private getAcceptLanguage 获取HTTP_ACCEPT_LANGUAGE */ class UserLang{ // class start private $name = 'userlang'; // cookie name private $expire = 2592000; // cookie expire 30 days /** 初始化 * @param String $name cookie name * @param int $expire cookie expire */ public function __construct($name='', $expire=null){ // 设置cookie name if($name!=''){ $this->name = $name; } // 设置cookie expire if(is_numeric($expire) && $expire>0){ $this->expire = intval($expire); } } /** 获取用户访问语言 */ public function get(){ // 判断用户是否有设置过语言 if(isset($_COOKIE[$this->name])){ $lang = $_COOKIE[$this->name]; }else{ $lang = $this->getAcceptLanguage(); } return $lang; } /** 设置用户访问语言 * @param String $lang 用户访问语言 */ public function set($lang=''){ $lang = strtolower($lang); // 只能是英文,简体中文,繁体中文 if(in_array($lang, array('en','sc','tc'))){ setcookie($this->name, $lang, time()+$this->expire); } } /** 获取HTTP_ACCEPT_LANGUAGE */ private function getAcceptLanguage(){ $lang = strtolower($_SERVER['HTTP_ACCEPT_LANGUAGE']); if(in_array(substr($lang,0,5), array('zh-tw','zh_hk'))){ $lang = 'tc'; }elseif(in_array(substr($lang,0,5), array('zh-cn','zh-sg'))){ $lang = 'sc'; }else{ $lang = 'en'; } return $lang; } } // class end ?>
demo示例程序如下:
<?php require "UserLang.class.php"; $obj = new UserLang('sitelang', 3600); echo $obj->get().'<br>'; ?>
希望本文所述对大家PHP程序设计的学习有所帮助。
