Php determines whether a mobile phone is accessed or a computer browser

Method 1

<? Php function isMobile () {$ useragent = isset ($ _ SERVER ['HTTP_USER_AGENT'])? $ _ SERVER ['HTTP_USER_AGENT']: '; $ useragent_commentsblock = preg_match (' | (.*?) | ', $ Useragent, $ matches)> 0? $ Matches [0]: ''; function CheckSubstrs ($ substrs, $ text) {foreach ($ substrs as $ substr) if (false! = Strpos ($ text, $ substr) {return true;} return false;} $ mobile_ OS _list = array ('Google Wireless Transcoder', 'Windows CE', 'WindowsCE ′, 'symbian ', 'Android', 'armv6l', 'armv5', 'mobile ', 'centos', 'mobab', 'avantgo ', 'Opera mobi ′, 'j2'/MIDP ', 'Smartphone', 'Go. web ', 'Palm', 'ipaq '); $ mobile_token_list = array ('Profile/MIDP', 'configuration/CLDC-',' 160 × 160 ′, '176 × 220', '240 × 240', '240 × 320', '320 × 240', 'Up. browser ', 'Up. li Nk ', 'symbianos', 'palmos ', 'pocketpc', 'sonyericsson', 'Nokia ', 'BlackBerry', 'Vodafone', 'benq ′, 'novarra-Vision ', 'Iris', 'netfron', 'HTC _ ', 'xda _', 'SAMSUNG-SGH ', 'wapaka', 'docomo ', 'iPhone ′, 'iPod '); $ found_mobile = CheckSubstrs ($ mobile_ OS _list, $ useragent_commentsblock) | CheckSubstrs ($ mobile_token_list, $ useragent); if ($ found_mobile) {return true ;} else {return false ;}} if (isMobile () echo 'visit DD blog'; el Se echo 'computer access DD blog';?>

Method 2

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 '],); $ mobile_agents = array ('w3c', 'ACS -′, 'alav', 'alca', 'amo' I ', 'Audi', 'avance', 'benq', 'bird ', 'blac', 'blaz', 'brew ′, 'Cell ', 'cldc', 'cmd-', 'Dang ', 'doco', 'Eric', 'hipt', 'inno', 'ipaq ′, 'Java ', 'jeigs', 'kddi ', 'Keji', 'Leno', 'LG-C', 'LG-D', 'LG-G', 'lge-', 'mau ′, 'maxo', 'midp ', 'mits', 'mmef', 'mobi', 'mot-', 'Moto', 'mwbp ', 'Nec -′, 'Newt ', 'noki', 'rank', 'Palm ', 'pana', 'pant ', 'Phil', 'play', 'port', 'prox ′, 'qwap ', 'Sage', 'sams', 'sany', 'Sch-', 'SEC-', 'send', 'seri', 'sgh -′, 'Shar ', 'sie-', 'Siem ', 'smal', 'smar', 'Sony ', '7d-', 'symb', 'T-M ′, '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; elsereturn false ;}

I have tested both of these methods and hope they will be useful to you.
