添加 browscap 插件 - 无需修改 php.ini

• http://browscap.org/

• browscap/browscap-php

• 刚安装完 php5 后,原来网站调用 get_browser() 出现如下错误:

2016/05/14 09:51:23 [error] 32417#32417: *4 FastCGI sent in stderr: 
"PHP message: PHP Warning:  get_browser(): browscap ini directive not set in /data/home/coam/ServerCoam/LogisticsPlatform/applications/controllers/ControllerBase.php on line 25

• 下面开始测试安装 browscap 插件

coam@coam:~$ cd /ServerCoam/Home/applications/plugins
coam@coam:~/ServerCoam/Home/applications/plugins$ git clone https://github.com/browscap/browscap-php BrowsCap
coam@coam:~/ServerCoam/Home/applications/plugins$ cd BrowsCap
coam@coam:~/ServerCoam/Home/applications/plugins$ composer install

• 必须通过命令自动下载 browscap.ini

coam@coam:~/ServerCoam/Home/applications/plugins/BrowsCap$ bin/browscap-php browscap:fetch
coam@coam:~/ServerCoam/Home/applications/plugins/BrowsCap$ bin/browscap-php browscap:convert

否则 通过 $this->BrowsCap->getBrowser(); 获取的信息都是空白

• 通过命令自动更新 browscap.ini

sudo ./bin/browscap-php browscap:update

• 引入文件测试:

<? php
require 'vendor/autoload.php';

// The Browscap class is in the BrowscapPHP namespace, so import it
use BrowscapPHP\Browscap;

// Create a new Browscap object (loads or creates the cache)
$bc = new Browscap();

// Get information about the current browser's user agent
$current_browser = $bc->getBrowser();

实测性能与php.ini加载的方式没有什么性能提升,应把原来的php.ini中对 browscap 的 配置注释掉

性能有巨大的提升,并且不用修改配置php.ini文件

使用 browscap.ini 让php识别客户端浏览器 – 旧版,性能不高,已弃用

• 首先添加 browscap 到 php.ini

<?php
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";

$browser = get_browser(null, true);
print_r($browser);
?>
