一个PHP判断手机设备的代码

现在移动互联网越来越发到，很多的网站都普及了手机端浏览，为了更好的让网页在手机端显示，我们都选择了使用CSS媒体查询制作响应式模版，但这也有弊端，例如某些网站的结构是CMS类型的，太多的内容要显示，而使用CSS媒体查询设计响应式，只会隐藏但还是加载了，为了让手机端更快速的显示出内容，我们可以使用这个PHP判断手机设备代码，使用这个代码可以很方便的显示或不显示自定义的内容。

这是PHP判断手机设备函数代码，复制到PHP函数库中调用:
<?php
function is_mobile() {
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$mobile_browser = Array(
"mqqbrowser", //手机QQ浏览器
"opera mobi", //手机opera
"juc","iuc",//uc浏览器
"fennec","ios","applewebKit/420","applewebkit/525","applewebkit/532","ipad","iphone","ipaq","ipod",
"iemobile", "windows ce",//windows phone
"240×320","480×640","acer","android","anywhereyougo.com","asus","audio","blackberry","blazer","coolpad" ,"dopod", "etouch", "hitachi","htc","huawei", "jbrowser", "lenovo","lg","lg-","lge-","lge", "mobi","moto","nokia","phone","samsung","sony","symbian","tablet","tianyu","wap","xda","xde","zte"
);
$is_mobile = false;
foreach ($mobile_browser as $device) {
if (stristr($user_agent, $device)) {
$is_mobile = true;
break;
}
}
return $is_mobile;
}?>

这是调用代码，可以加上if判断:
<?php if(is_mobile()):?>
设置手机端的内容
<?php endif; ?>
