正確なブラウザ名とバージョンを取得する方法は？
いくつかの解決策を試しましたが、正確な名前とバージョンを取得できません。
次のコードを試しています：
$browserAgent = $_SERVER['HTTP_USER_AGENT'];
echo $browserAgent;
上記のコードの出力：
Mozilla/5.0 (X11; Linux i686) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.68 Safari/534.24
しかし、私は使用しています：
Google Chrome 11.0.696.68
on
Ubuntu 10.04
したがって、出力文字列のChrome/11.0.696.68で見つけることができますが、文字列から正確なブラウザname/versionを抽出するのが混乱している他のブラウザ名も表示しています。
get_browser() を使用します
マニュアルから：
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";
$browser = get_browser(null, true);
print_r($browser);
戻ります：
Array
(
[browser_name_regex] => ^mozilla/5\.0 (windows; .; windows nt 5\.1; .*rv:.*) gecko/.* firefox/0\.9.*$
[browser_name_pattern] => Mozilla/5.0 (Windows; ?; Windows NT 5.1; *rv:*) Gecko/* Firefox/0.9*/
[parent] => Firefox 0.9
[platform] => WinXP
[browser] => Firefox
[version] => 0.9
[majorver] => 0
[minorver] => 9
[cssversion] => 2
[frames] => 1
[iframes] => 1
[tables] => 1
[cookies] => 1
[backgroundsounds] =>
[vbscript] =>
[javascript] => 1
[javaapplets] => 1
[activexcontrols] =>
[cdf] =>
[aol] =>
[beta] => 1
[win16] =>
[crawler] =>
[stripper] =>
[wap] =>
[netclr] =>
)
このJavaScriptはブラウザ名とバージョンを提供し、
var browser = '';
var browserVersion = 0;
if (/Opera[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
browser = 'Opera';
} else if (/MSIE (\d+\.\d+);/.test(navigator.userAgent)) {
browser = 'MSIE';
} else if (/Navigator[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
browser = 'Netscape';
} else if (/Chrome[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
browser = 'Chrome';
} else if (/Safari[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
browser = 'Safari';
/Version[\/\s](\d+\.\d+)/.test(navigator.userAgent);
browserVersion = new Number(RegExp.$1);
} else if (/Firefox[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
browser = 'Firefox';
}
if(browserVersion === 0){
browserVersion = parseFloat(new Number(RegExp.$1));
}
alert(browser + "*" + browserVersion);
awesome関数 here を取得しました。

この素晴らしいクラスを提案したいと思います。これは私にとって非常にうまくいきました。

（Safari）と（Opera）と（Chrome）の間に矛盾があります!!!
上記のコードは適切に機能しませんでした
これは私のコードであり、競合することなく非常にうまく機能します：
function ExactBrowserName()
{
$ExactBrowserNameUA=$_SERVER['HTTP_USER_AGENT'];
if (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")) {
// OPERA
$ExactBrowserNameBR="Opera";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "chrome/")) {

} elseIf (strpos(strtolower($ExactBrowserNameUA), "msie")) {
// INTERNET Explorer
$ExactBrowserNameBR="Internet Explorer";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "firefox/")) {

} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")==false and strpos(strtolower($ExactBrowserNameUA), "chrome/")==false) {

このページには @ AlexV による comment があり、これは BrowserDetection について説明しています。
これは素晴らしいクラスだと思うし、独自の答えに値する。私はちょうどそれを使用し、魅力のように動作します（非常に使いやすい）。
51Degrees.comデバイス検出ソリューションを使用して、ブラウザー名、ベンダー、およびバージョンを検出します。
まず、 4-step guide に従って、デバイス検出器をプロジェクトに組み込みます。組み込みとは、PHPコードとデータベースファイルを含むアーカイブをダウンロードし、それらを抽出して2つのファイルを含めるという意味です。組み込むにはこれですべてです。
それが完了したら、次のプロパティを使用してブラウザ情報を取得できます。
$ _ 51d ['BrowserName'] -ブラウザの名前を指定します（Safari、Molto、Motorola、MStarBrowserなど）。
$ _ 51d ['BrowserVendor'] -ブラウザを作成した会社を提供します。
$ _ 51d ['BrowserVersion'] -ブラウザーのバージョン番号
