最近移動互聯(lián)網火爆了我們需要做一個PC站與WAP站,要實現(xiàn)如果用戶是電腦訪問WAP站就自動進入PC站,反之一樣,下面我整理了一些代碼與大家一起來看看.

方法一,判斷HTTP_USER_AGENT,代碼如下:

$agent = strtolower($_SERVER['HTTP_USER_AGENT']);

if(strpos($agent,"netfront") || strpos($agent,"iphone") || strpos($agent,"midp-2.0") || strpos($agent,"opera mini") || strpos($agent,"ucweb") || strpos($agent,"android") || strpos($agent,"windows ce") || strpos($agent,"symbianos")) {

    Header("HTTP/1.1 301 Moved Permanently");

    header("Location:####");  die;

}

方法二,判斷HTTP_ACCEPT,代碼如下:

if (isset($_SERVER['HTTP_ACCEPT']) && (strpos($_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')) )) {//手機訪問

    Header("HTTP/1.1 301 Moved Permanently");

    header("Location:####"); die;

}

以上兩個方法都有局限性,下面將此兩種方法整合起來判斷,代碼如下:

function isMobile() {

    if(isset($_SERVER['HTTP_X_WAP_PROFILE'])) {

        return true;

    }

    if(isset ($_SERVER['HTTP_VIA'])) {

        //找不到為flase,否則為true

        return stristr($_SERVER['HTTP_VIA'], "wap") ? true : false;

    }

    if(isset($_SERVER['HTTP_USER_AGENT'])) {

        //此數(shù)組有待完善

        $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'

        );

        // 從HTTP_USER_AGENT中查找手機瀏覽器的關鍵字

        if(preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) {

            return true;

        }



    }



    //協(xié)議法，因為有可能不準確，放到最后判斷

    if (isset ($_SERVER['HTTP_ACCEPT'])) {

        // 如果只支持wml并且不支持html那一定是移動設備

        // 如果支持wml和html但是wml在html之前則是移動設備

        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;

}

上面的方法也存在一些小問題,這里我根據(jù)自己的經驗來告訴大我們可以使用屏幕寬度來實現(xiàn)再加機器類型了,因為有時HTTP_USER_AGENT信息在我們上面并未定義過了,不過上面實現(xiàn)幾乎兼容了主流手機了.

我們還可以使用js:

<html>

<body>

  <script type="text/javascript">

   function browserRedirect() {

    var sUserAgent = navigator.userAgent.toLowerCase();

    var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";

    var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";

    var bIsMidp = sUserAgent.match(/midp/i) == "midp";

    var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";

    var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";

    var bIsAndroid = sUserAgent.match(/android/i) == "android";

    var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";

    var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";

    if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {

     window.location.href = 'http://url/mobile.html';

    } else {

     window.location = 'http://url/pc.html';

    }

   }

   browserRedirect();

  </script>

</body>

</html>
