I am using a function to identify mobile browsers in my projects, which can detect almost all major Mobile Operating systems and browsers.

我正在使用一個功能來識別我的項目中的移動瀏覽器,它可以檢測幾乎所有主要的移動操作系統和瀏覽器。

function ismobile() {

$is_mobile = '0';

if(preg_match('/(android|up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {

$is_mobile=1;

}

if((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml')>0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE'])))) {

$is_mobile=1;

}

$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));

$mobile_agents = array('w3c ','acs-','alav','alca','amoi','andr','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)) {

$is_mobile=1;

}

if (isset($_SERVER['ALL_HTTP'])) {

if (strpos(strtolower($_SERVER['ALL_HTTP']),'OperaMini')>0) {

$is_mobile=1;

}

}

if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows')>0) {

$is_mobile=0;

}

return $is_mobile;

}
