JavaScript 判断方法是直接搜索客户端的user agent字符串中的 Android 字符串:
- if(navigator.userAgent.match(/Android/i)) {
- alert('Is Android !');
- } else {
- alert('Is Not Android !');
- }
PHP 方法判断,同样可以搜索 user agent 中是否有 Android 关键字:
- if(strstr($_SERVER['HTTP_USER_AGENT'],'Android')) {
- echo 'Is Android !';
- } else {
- echo 'Is Not Android !';
- }
再来介绍一下关于php根据HTTP_USER_AGENT 判断用户浏览器类型:
- function browsers(){
- global $HTTP_USER_AGENT ;
- if (isset($HTTP_USER_AGENT)){
- $sAgent = $HTTP_USER_AGENT;
- }else{
- $sAgent = $_SERVER['HTTP_USER_AGENT'];
- }
- if (strpos($sAgent,'MSIE') !== false && strpos($sAgent,'mac') === false && strpos($sAgent,'Opera') === false){
- $iVersion = (float)substr($sAgent,strpos($sAgent,'MSIE') + 5,3);
- return ($iVersion >= 5.5) ;
- }else if (strpos($sAgent,'Gecko/') !== false){
- $iVersion = (int)substr($sAgent,strpos($sAgent,'Gecko/') + 6,8);
- return ($iVersion >= 20030210) ;
- }else{
- return false;
- }
- }
