有时候很实用在一些场合，留住备用吧
复制代码 代码如下:
function is_mobile_request()
{
$_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';
$mobile_browser = '0';
if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT'])))
$mobile_browser++;
if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))
$mobile_browser++;
if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
$mobile_browser++;
if(isset($_SERVER['HTTP_PROFILE']))
$mobile_browser++;
$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));

php 根据HTTP_USER_AGENT 判断用户浏览器类型
复制代码 代码如下:
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;
}
}
