PHP - get_browser（）结果 [英] PHP - get_browser() results

问题描述

我使用了 get_browser（）功能，我安装了最新的 php_browscap.ini 文件< A HREF =htt​​p://tempdownloads.browserscap.com/相对=nofollow> http://tempdownloads.browserscap.com/ ，更新了我的的php.ini 文件反映新的位置。

I'm using the get_browser() function, and I installed the latest php_browscap.ini file from http://tempdownloads.browserscap.com/, updated my php.ini file to reflect the new location.

下面是我简单的code我从PHP的网站上收集到的：

Here's my simple code I've gleaned from PHP's site:

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

和的结果是这样的：

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0

Array ( [browser_name_regex] => �^mozilla/5\.0 \(.*windows nt 6\.1.*wow64.*\).*gecko/.*firefox/21\..*$� [browser_name_pattern] => Mozilla/5.0 (*Windows NT 6.1*WOW64*)*Gecko/*Firefox/21.* [parent] => Firefox 21.0 [platform] => Win7 [platform_version] => 6.1 [win32] => [win64] => 1 [comment] => Firefox 21.0 [browser] => Firefox [version] => 21.0 [majorver] => 21 [minorver] => 0 [beta] => 1 [frames] => 1 [iframes] => 1 [tables] => 1 [cookies] => 1 [javascript] => 1 [javaapplets] => 1 [cssversion] => 3 [alpha] => [win16] => [backgroundsounds] => [vbscript] => [activexcontrols] => [ismobiledevice] => [issyndicationreader] => [crawler] => [aolversion] => 0 ) 

我看到在 [browser_name_regex] 部分一个奇怪的字符。结果
该预期是什么？

I'm seeing a weird character in the [browser_name_regex] section.
Is that expected?

另外，我

推荐答案

虽然这不是预期，但它是允许的。我从 get_browser（）函数是 [browser_name_regex] =＆GT输出; §^ * $§。它只是有两个段落，而不是施加的斜线 /^.*$/ 。

Although it's not expected, but it's allowed. My output from the get_browser() function was [browser_name_regex] => §^.*$§. It just has two paragraphs instead of exerted slashes /^.*$/.

说明：

分隔符可以是除反斜线（\\）和空字节任何非字母数字，非空白ASCII字符。 （链接）

Delimiters can be any non-alphanumeric, non-whitespace ASCII character except the backslash (\) and the null byte. (link)

你所看到的仅仅是包裹着分隔符是\\ xA7一个PCRE模式。要得到
  浏览器匹配你需要一个版本的browscap.ini它通过的链接可下载
  在文档页面。 （链接）

What you see is merely a pcre pattern wrapped with delimiter which is \xA7. To get browsers matching you'll need a browscap.ini which is downloadable by the links on the doc page. (link)
