PHP简单判断手机设备的方法 PHP判断手机设备的代码

PHP简单判断手机设备的方法。分享给大家供大家参考，具体如下：

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; ?>
