PHP通过内置全局变量$_SERVER['HTTP_USER_AGENT']来获取用户信息，包括浏览器信息，操作系统等；判断是否是手机还是电脑终端访问，只需判断他的$_SERVER['HTTP_USER_AGENT']信息是否存在手机终端类型即可。示例如下：

<?php

//1.获取用户浏览器信息 等；

$user_agent = $_SERVER['HTTP_USER_AGENT'];

//2.列举常用手机终端类型

$mobile_agents = array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi",

"android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio",

foreach ($mobile_agents as $device) {

if (stristr($user_agent, $device)) {

//手机访问

$is_mobile = true;

break;

}

}

//判断手机标识是否为真

if($is_mobile){

echo "手机访问！";

}else{

echo "电脑访问！";

}
