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。

1. 这是PHP判断手机设备函数代码，复制到PHP函数库中调用:
2. <?php
3. function is_mobile() {
4. $user_agent = $_SERVER["HTTP_USER_AGENT"];
5. $mobile_browser = Array(
6. "mqqbrowser", //手机QQ浏览器
7. "opera mobi", //手机opera
8. "juc","iuc",//uc浏览器
9. "fennec","ios","applewebKit/420","applewebkit/525","applewebkit/532","ipad","iphone","ipaq","ipod",
10. "iemobile", "windows ce",//windows phone
11. "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"
12. );
13. $is_mobile = false;
14. foreach ($mobile_browser as $device) {
15. if (stristr($user_agent, $device)) {
16. $is_mobile = true;
17. break;
18. }
19. }
20. return $is_mobile;
21. }?>
22.  
23. 这是调用代码，可以加上if判断:
24. <?php if(is_mobile()):?>
25. 设置手机端的内容
26. <?php endif; ?>
