隨著移動設(shè)備的普及，網(wǎng)站也會迎來越來越多移動設(shè)備的訪問。用適應(yīng)PC的頁面，很多時候?qū)κ謾C(jī)用戶不友好，那么有些時候，我們需要判斷用戶是否用手機(jī)訪問，如果是手機(jī)的話，就跳轉(zhuǎn)到指定的手機(jī)友好頁面。這里就介紹一下，如何判斷用戶是否用手機(jī)訪問。
自定義的函數(shù)如下：
$agent = check_wap();if( $agent ){ header('Location: http://www.nowamagic.net'); exit;}// check if wap function check_wap(){ // 先檢查是否為wap代理，準(zhǔn)確度高 if(stristr($_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(jī)移動終端的函數(shù)：
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; }
