如何通过User-Agent禁止电脑端访问

如何通过User-Agent禁止电脑端访问

根据UA信息判断 是pc还是移动设备啊，wordpress源码里有一个这功能函数我感觉挺好用的，

1. /*PHP判断是否是移动端*/
   
2. function is_mobile() {
   
3. if ( empty($_SERVER['HTTP_USER_AGENT']) ) {
   
4. return false;
   
5. } elseif (strpos($_SERVER['HTTP_USER_AGENT'], 'Mobile') !== false
   
6. || strpos($_SERVER['HTTP_USER_AGENT'], 'Android') !== false
   
7. || strpos($_SERVER['HTTP_USER_AGENT'], 'Silk/') !== false
   
8. || strpos($_SERVER['HTTP_USER_AGENT'], 'Kindle') !== false
   
9. || strpos($_SERVER['HTTP_USER_AGENT'], 'BlackBerry') !== false
   
10. || strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mini') !== false
    
11. || strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mobi') !== false ) {
    
12. return true;
    
13. } else {
    
14. return false;
    
15. }
    
16. }
