php網站判斷使用者是否是手機訪問的方法

隨著移動裝置的普及，網站也會迎來越來越多移動裝置的訪問。用適應PC的頁面，很多時候對手機使用者不友好，那麼有些時候，我們需要判斷使用者是否用手機訪問，如果是手機的話，就跳轉到指定的手機友好頁面。這裡就介紹一下，如何判斷使用者是否用手機訪問。 自定義的函式如下：

$agent = check_wap(); if( $agent ) { header('Location: http://www.nowamagic.net'); exit; }

// check if wap function check_wap(){ // 先檢查是否為wap代理，準確度高 if(stristr($_SERVER['HTTP_VIA'],"wap")){ return true; } // 檢查瀏覽器是否接受 WML. elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){ return true; } //檢查USER_AGENT elseif(preg_match('/(blackberry|configuration\/cldc|hp |hp-|htc |htc_|htc-|iemobile|kindle|midp|mmp|motorola|mobile|nokia|opera mini|opera |Googlebot-Mobile|YahooSeeker\/M1A1-R2D2|android|iphone|ipod|mobi|palm|palmos|pocket|portalmmm|ppc;|smartphone|sonyericsson|sqh|spv|symbian|treo|up.browser|up.link|vodafone|windows ce|xda |xda_)/i', $_SERVER['HTTP_USER_AGENT'])){ return true;
} else{ return false;
} }

再來一個從PHP框架剝離的判斷是否為手機移動終端的函式：（經過測試，很全面，推薦使用）

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;
