如何使用userAgent檢測移動設備

Question

誰能幫我這個。

我想檢測諸如Iphone，BB，andriod和瀏覽器之類的設備，以應用它們的特定css使其液化或調整到它們的分辨率。

Andriod和Iphone在移動瀏覽器方面有不同的分辨率問題或css問題，因為我打算為那些2使用相同的css，因為我知道他們使用相同的瀏覽器safari作為默認。

Answer 1

以下是javascript中的示例：

var isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/);

if(isMobile) {
   // User-Agent is IPhone, IPod, IPad, Android or BlackBerry
}

要檢查特定的User-Agent字符串，您可以執行以下操作：

if(navigator.userAgent.match(/iPhone/)) {
   // The User-Agent is iPhone
}

Answer 2

嘗試使用http://www.php.net/get_browser並檢查isMobileDevice字段。 當然，如果在php.ini中設置browscap.ini的路徑，它可能只有幫助。 如果沒有，你可以使用像https://github.com/garetjax/phpbrowscap這樣的php類

Answer 3

<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;  user-scalable=0;" />
<meta name="HandheldFriendly" content="true"/>
<meta name="MobileOptimized" content="320"/>
<meta http-equiv="cleartype" content="on" />


use this code on your website under <header> tag.

這是移動設備檢測的代碼。

 function isMobile() {

// Check the server headers to see if they're mobile friendly
if(isset($_SERVER["HTTP_X_WAP_PROFILE"])) {
    return true;
}

// If the http_accept header supports wap then it's a mobile too
if(preg_match("/wap\.|\.wap/i",$_SERVER["HTTP_ACCEPT"])) {
    return true;
}

// Still no luck? Let's have a look at the user agent on the browser. If it contains
// any of the following, it's probably a mobile device. Kappow!
if(isset($_SERVER["HTTP_USER_AGENT"])){
    $user_agents = array("midp", "j2me", "avantg", "docomo", "novarra", "palmos", "palmsource", "240x320", "opwv", "chtml", "pda", "windows\ ce", "mmp\/", "blackberry", "mib\/", "symbian", "wireless", "nokia", "hand", "mobi", "phone", "cdm", "up\.b", "audio", "SIE\-", "SEC\-", "samsung", "HTC", "mot\-", "mitsu", "sagem", "sony", "alcatel", "lg", "erics", "vx", "NEC", "philips", "mmm", "xx", "panasonic", "sharp", "wap", "sch", "rover", "pocket", "benq", "java", "pt", "pg", "vox", "amoi", "bird", "compal", "kg", "voda", "sany", "kdd", "dbt", "sendo", "sgh", "gradi", "jb", "\d\d\di", "moto");
    foreach($user_agents as $user_string){
        if(preg_match("/".$user_string."/i",$_SERVER["HTTP_USER_AGENT"])) {
            return true;
        }
    }
}

// Let's NOT return "mobile" if it's an iPhone, because the iPhone can render normal pages quite well.
if(preg_match("/iphone/i",$_SERVER["HTTP_USER_AGENT"])) {
    return false;
}

// None of the above? Then it's probably not a mobile device.
return false;
}
    if (isMobile()) {
   header("location:$mobile");
  // if the function returned true, it's a mobile.
  //echo "mobile"; // delete this line in your code, and uncomment the next line
 // header('Location: http://www.yoursite.mobi/'); // let's redirect the page to   the mobile site

   }

希望這會幫助你。

Answer 4

我用這個：

$mobile= stripos( $_SERVER['HTTP_USER_AGENT'], 'mob');

它幾乎每次都有效。

使用Javascript

var mobile= navigator.userAgent.toLowerCase().indexOf( 'mob');

-1如果不移動; 移動時的任何其他價值

$useragent=$_SERVER['HTTP_USER_AGENT'];

Answer 7

您可以使用CSS Media Queries來識別不同的設備（實際上是不同的設備功能，如設備寬度，dpi等）

對於CSS，您可以有不同的選項，例如為每種類型的設備使用單獨的CSS或具有流體設計，這意味着對於不同的設備大小具有相同的CSS比例。 第二種方法設計稍微復雜一些，但從未來可能出現的新設備中可以靈活得多。
