2, use PHP code to determine whether the browser is a mobile terminal

function isMobile() { // 如果有HTTP_X_WAP_PROFILE则一定是移动设备 if (isset ($_SERVER['HTTP_X_WAP_PROFILE'])) { return "1"; } // 如果via信息含有wap则一定是移动设备 if (isset ($_SERVER['HTTP_VIA'])) { // 找不到为flase,否则为true return stristr($_SERVER['HTTP_VIA'], "wap") ? "1" : "0"; } // 脑残法，判断手机发送的客户端标志,兼容性有待提高 if (isset ($_SERVER['HTTP_USER_AGENT'])) { $clientkeywords = array ('nokia', 'sony', 'ericsson', 'mot', 'samsung', 'htc', 'sgh', 'lg', 'sharp', 'sie-', 'philips', 'panasonic', 'alcatel', 'lenovo', 'iphone', 'ipod', 'blackberry', 'meizu', 'android', 'netfront', 'symbian', 'ucweb', 'windowsce', 'palm', 'operamini', 'operamobi', 'openwave', 'nexusone', 'cldc', 'midp', 'wap', 'mobile' ); // 从HTTP_USER_AGENT中查找手机浏览器的关键字 if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) { return "1"; } } // 协议法，因为有可能不准确，放到最后判断 if (isset ($_SERVER['HTTP_ACCEPT'])) { // 如果只支持wml并且不支持html那一定是移动设备 // 如果支持wml和html但是wml在html之前则是移动设备 if ((strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false) && (strpos($_SERVER['HTTP_ACCEPT'], 'text/html') === false || (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') < strpos($_SERVER['HTTP_ACCEPT'], 'text/html')))) { return "1"; } } return "0"; } $ismobile=isMobile();//判断是否移动端 if ($ismobile=="1"){ echo "浏览器为移动端"; } if ($ismobile=="0"){ echo "浏览器不为移动端"; }
