Вот скрипт PHP, чтобы сделать это:
<?php
/* MOBILE DETECT */
$mobile_browser = '0';
if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone)/i', strtolower($_SERVER['HTTP_USER_AGENT']))):
$mobile_browser++;
endif;
if((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml')>0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE'])))):
$mobile_browser++;
endif;
$mobile_ua = strtolower(substr($_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)):
$mobile_browser++;
endif;
if(strpos(strtolower($_SERVER['ALL_HTTP']),'operamini')>0):
$mobile_browser++;
endif;
if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows')>0):
$mobile_browser=0;
endif;
if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'iemobile')>0):
$mobile_browser++;
endif;
if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']),' ppc;')>0):
$mobile_browser++;
endif;
if($mobile_browser>0):
echo "mobile";
else:
echo "nix mobile";
endif;
?>
