如何在PHP中访问数组成员

Question

我只是想知道如何使用这段代码只取浏览器名称。

<?php
echo $_SERVER['HTTP_USER_AGENT'] . "nn";
$browser = get_browser(null, true);
print_r($browser);
?>

Answer 1

$browser['browser']

你的代码将输出:

`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] =>
        )`

如果您不能或不能够安装browscap.ini (get_browser中需要)，您应该使用一些现成的类。我谷歌了一下，发现了这个:http://chrisschuld.com/projects/browser-php-detecting-a-users-browser-from-php/

希望它有帮助!

下面是使用代码的示例:

$user_browser = new Browser();
if($user_browser->getBrowser() == Browser::BROWSER_CHROME){
echo 'Your browser seems to be Google Chrome!';
}

或者如果你只想打印简短的浏览器版本，

$user_browser = new Browser();
print $user_browser->getBrowser();

类自己页面的注释甚至说它比PHP的get_browser(链接到这里注释)
