本文主要是介绍查到的一个限制只能手机访问的封装类，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

工作需要网上搜索查到一个限制只能手机访问的封装类，亲测可用，再此推荐下

function is_mobile_request()   {   $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';   $mobile_browser = '0';   if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT'])))   $mobile_browser++;   if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))   $mobile_browser++;   if(isset($_SERVER['HTTP_X_WAP_PROFILE']))   $mobile_browser++;   if(isset($_SERVER['HTTP_PROFILE']))   $mobile_browser++;   $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));   $mobile_agents = array(   'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',   'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',   'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',   'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',   'newt','noki','oper','palm','pana','pant','phil','play','port','prox',   'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',   'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',   'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',   'wapr','webc','winw','winw','xda','xda-'   );   if(in_array($mobile_ua, $mobile_agents))   $mobile_browser++;   if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false)   $mobile_browser++;   // Pre-final check to reset everything if the user is on Windows   if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false)   $mobile_browser=0;   // But WP7 is also Windows, with a slightly different characteristic   if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false)   $mobile_browser++;   if($mobile_browser>0)   return true;   else  return false;   }
