php 判断是否是电脑访问,php

下面是一个从PHP框架剥离出来判断是否为手机移动终端的函数：(已全面测试通过，值的推荐)

echo is_mobile_request()?"手机访问":"电脑访问";

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));
