判斷是否為手機引入不同模板

function isMobile() {
    // 如果有HTTP_X_WAP_PROFILE則一定是移動裝置
    if (isset($_SERVER['HTTP_X_WAP_PROFILE'])) {
        return true;
    }
    // 如果via資訊含有wap則一定是移動裝置,部分服務商會遮蔽該資訊
    if (isset($_SERVER['HTTP_VIA'])) {
        // 找不到為flase,否則為true
        return stristr($_SERVER['HTTP_VIA'], "wap"
 
) ? true : false;
    }
    // 腦殘法，判斷手機發送的客戶端標誌,相容性有待提高。其中'MicroMessenger'是電腦微信
    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','MicroMessenger');
        // 從HTTP_USER_AGENT中查詢手機瀏覽器的關鍵字
        if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) {
            return
 
 true;
        }
    }
    // 協議法，因為有可能不準確，放到最後判斷
    if (isset ($_SERVER['HTTP_ACCEPT'])) {
        // 如果只支援wml並且不支援html那一定是移動裝置
        // 如果支援wml和html但是wml在html之前則是移動裝置
        if ((strpos($_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 true;
        }
    }
    return false;
}

根據判斷跳轉到手機網站

 $ua = strtolower($_SERVER['HTTP_USER_AGENT']);
 $uachar = "/(iphone|android|phone|mobile|wap|netfront|java|opera mobi|opera mini|ucweb|windows ce|symbian|series|webos|sony|blackberry|dopod|nokia|samsung|palmsource|xda|pieplus|meizu|midp|cldc

 |alcatel|amoi|ktouch|nexian|ericsson|philips|sagem|wellcom|bunjalloo|maui|smartphone|iemobile|spice|bird|zte-|longcos|pantech|gionee|portalmmm|jig
 browser|hiptop|benq|haier|^lct|320x320|240x320|176x220)/i";
if(($ua == '' || preg_match($uachar, $ua))&& !strpos(strtolower($_SERVER['REQUEST_URI']),'wap'))
{
     $Loaction = 'http://m.domain.com'; //填寫需要跳轉的地址
     if (!empty($Loaction))
     {
         header("Location: $Loaction\n");
         exit;
     }
}
