多语言用户选择机制
本文以thinkphp多语言切换为例,实际项目中的原创代码,分享给大家。
多语言切换四点要求如下:
1.首先判断用户有无手动指定语言
2.从session中获得当前语言
3.session里面没有则从cookie里面去取
4.若是cookie里没有,则根据IP段判断
5.若不在指定ip范围内,自动侦测浏览器语言
代码如下:private function checkLanguage() {<br>
// 不开启语言包功能,仅仅加载框架语言文件直接返回<br>
if (!C('LANG_SWITCH_ON',null,false)){<br>
return;<br>
}<br>
// 启用了语言包功能<br>
$langSet = C('DEFAULT_LANG');<br>
$varLang = C('VAR_LANGUAGE',null,'l');<br>
$langList = C('LANG_LIST',null,'en');<br>
<br>
// session_start();<br>
// 首先判断用户有无手动指定语言<br>
if(!empty($_GET[$varLang]))<br>
{<br>
$selectLang = $_GET[$varLang]; <br>
}<br>
if (isset($selectLang)) {<br>
// 切换语言<br>
$langSet = $selectLang;<br>
$abc='用户自己设置语言';<br>
if (false === stripos($langList, $langSet)) $langSet = C('DEFAULT_LANG');// 非法语言参数<br>
$this->selectLang($langSet);<br>
} else {<br>
// 从session中获得当前语言<br>
$sessionLang = session('rm_selected_language');<br>
if(isset($sessionLang))<br>
{<br>
$abc='从Session中获得';<br>
$langSet = $sessionLang;<br>
if (false === stripos($langList, $langSet)) {<br>
$langSet = C('DEFAULT_LANG');// 非法语言参数<br>
$this->selectLang($langSet); // 刷新成正确的值<br>
}<br>
} else {<br>
if (cookie('rm_selected_language')) {// 获取上次用户的选择<br>
$langSet = cookie('rm_selected_language');<br>
$abc='获取上次用户的选择';<br>
} elseif (null !== $this->getLangTypeByIP()) {<br>
//优先级2 根据IP段判断<br>
$langSet = $this->getLangTypeByIP();<br>
$abc='根据IP段判断';<br>
} elseif (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {// 自动侦测浏览器语言<br>
preg_match('/^([a-z\d\-]+)/i', $_SERVER['HTTP_ACCEPT_LANGUAGE'], $matches);<br>
//优先级3 根据浏览器语言判断<br>
$langSet = strtolower($matches[1]) == 'zh-cn' ? 'zh' : $matches[1];<br>
<br>
$abc='自动侦测浏览器语言';<br>
}<br>
if (false === stripos($langList, $langSet)) $langSet = C('DEFAULT_LANG');// 非法语言参数<br>
$this->selectLang($langSet);<br>
}<br>
}<br>
// 定义当前语言<br>
define('LANG_SET',strtolower($langSet));<br>
define('HELLO',$abc);<br>
<br>
// 读取框架语言包<br>
$file = THINK_PATH.'Lang/'.LANG_SET.'.php';<br>
if(LANG_SET != C('DEFAULT_LANG') && is_file($file))<br>
L(include $file);<br>
<br>
// 读取应用公共语言包<br>
$file = LANG_PATH.LANG_SET.'.php';<br>
if(is_file($file))<br>
L(include $file);<br>
<br>
// 读取模块语言包<br>
$file = MODULE_PATH.'Lang/'.LANG_SET.'.php';<br>
if(is_file($file))<br>
L(include $file);<br>
<br>
// 读取当前控制器语言包<br>
$file = MODULE_PATH.'Lang/'.LANG_SET.'/'.strtolower(CONTROLLER_NAME).'.php';<br>
if (is_file($file))<br>
L(include $file);<br>
}
开启多语言配置:'LANG_SWITCH_ON' => true, // 开启语言包功能<br>
'URL_CASE_INSENSITIVE' => true, //true 不区分大小写<br>
'LANG_LIST' => 'zh,en', // 允许切换的语言列表 用逗号分隔<br>
'VAR_LANGUAGE' => 'l', // 默认语言切换变量<br>
'DEFAULT_LANG' => 'zh',

Java Selection Sorting Method Code Writing Guide and Examples Selection sorting is a simple and intuitive sorting algorithm. The idea is to select the smallest (or largest) element from the unsorted elements each time and exchange it until all elements are sorted. This article will provide a code writing guide for selection sorting, and attach specific Java sample code. Algorithm Principle The basic principle of selection sort is to divide the array to be sorted into two parts, sorted and unsorted. Each time, the smallest (or largest) element is selected from the unsorted part and placed at the end of the sorted part. Repeat the above
