开源软件名称（OpenSource Name）：WhichBrowser/Parser-PHP开源软件地址(OpenSource Url)：https://github.com/WhichBrowser/Parser-PHP开源编程语言(OpenSource Language)：PHP 100.0%开源软件介绍(OpenSource Introduction)：This is an extremely complicated and almost completely useless browser sniffing library. Useless because you shouldn't use browser sniffing. So stop right now and go read something about feature detecting instead. I'm serious. Go away. You'll thank me later. WhichBrowser/Parser-PHPThe PHP version of WhichBrowser for use on a server. Fully compatible with PHP 7.0 or higher, including PHP 8.

About WhichBrowserBut why almost completely useless and not completely useless? Well, there is always an exception to the rule. There are valid reasons to do browser sniffing: to improve the user experience or to gather intelligence about which browsers are used on your website. My website is html5test.com and I wanted to know which score belongs to which browser. And to do that you need a browser sniffing library. Why is it extremely complicated? What kind of information does it give? You get a nice object which has information about the browser, rendering engine, os and device. It gives you names and versions and even device manufacturer and model. And WhichBrowser is pretty tenacious. It gives you info that others don't. For example: Android is never mentioned Despite the useragent header claiming to be a Series40 device, we know it's actually running the Asha Platform and we also know that OviBrowser has been renamed to Nokia Xpress. The useragent header looks like Opera 11.10 on Linux, but we know it's Opera Mini. We can even figure out the real operating system and device model from other headers. RequirementsWhichBrowser requires with PHP 7.0 or higher and supports PHP 8. WhichBrowser is compatible with the PSR-4 autoloading standard and follows PSR-1 and PSR-2 coding style. How to install itYou can install WhichBrowser by using Composer - the standard package manager for PHP. The package is called You can easily update WhichBrowser by running a simple command. You should run this command as often as possible. You might even want to consider setting up a cron job for this purpose. How to use itThe first step require the Composer autoloader: <?php
require 'vendor/autoload.php';The second step is to create a new For example: $result = new WhichBrowser\Parser(getallheaders());or: $result = new WhichBrowser\Parser($_SERVER['HTTP_USER_AGENT']);The variable First of all, you can call to "You are using " . $result->toString();
// You are using Chrome 27 on OS X Mountain Lion 10.8Another possiblity is to query the object: $result->isType('desktop');
// true
$result->isType('mobile', 'tablet', 'media', 'gaming:portable');
// false
$result->isBrowser('Maxthon', '<', '4.0.5');
// false
$result->isOs('iOS', '>=', '8');
// false
$result->isOs('OS X');
// true
$result->isEngine('Blink');
// trueYou can also access these properties directly: $result->browser->toString();
// Chrome 27
$result->engine->toString();
// Blink
$result->os->toString();
// OS X Mountain Lion 10.8Or access parts of these properties directly: $result->browser->name;
// Chrome
$result->browser->name . ' ' . $result->browser->version.toString();
// Chrome 27
$result->browser->version->value;
// 27.0.1453.110
$result->engine->name;
// BlinkFinally you can also query versions directly: $result->browser->version->is('>', 26);
// true
$result->os->version->is('<', '10.7.4');
// falseOptionsIt is possible to set additional options by passing an array as the second parameter when creating the Disabling detection of botsIn some cases you may want to disable the detection of bots. This allows the bot the deliberately fool WhichBrowser, so you can pick up the identity of useragent what the bot tries to mimic. This is especially handy when you want to use WhichBrowser to switch between different variants of your website and want to make sure crawlers see the right variant of the website. For example, a bot that mimics a mobile device will see the mobile variant of you site. $result = new WhichBrowser\Parser(getallheaders(), [ 'detectBots' => false ]);Enable result cachingWhichBrowser supports PSR-6 compatible cache adapters for caching results between requests. Using a cache is especially useful if you use WhichBrowser on every page of your website and a user visits multiple pages. During the first visit the headers will be parsed and the result will be cached. Upon further visits, the cached results will be used, which is much faster than having to parse the headers again and again. There are adapters available for other types of caches, such as APC, Doctrine, Memcached, MongoDB, Redis and many more. The configuration of these adapters all differ from each other, but once configured, all you have to do is pass it as an option when creating the For example, if you want to enable a memcached based cache you need to install an extra composer package: And change the call to WhichBrowser/Parser as follows: $client = new \Memcached();
$client->addServer('localhost', 11211);
$pool = new \Cache\Adapter\Memcached\MemcachedCachePool($client);
$result = new WhichBrowser\Parser(getallheaders(), [ 'cache' => $pool ]);or $client = new \Memcached();
$client->addServer('localhost', 11211);
$pool = new \Cache\Adapter\Memcached\MemcachedCachePool($client);
$result = new WhichBrowser\Parser();
$result->setCache($pool);
$result->analyse(getallheaders());You can also specify after how many seconds a cached result should be discarded. The default value is 900 seconds or 15 minutes. If you think WhichBrowser uses too much memory for caching, you should lower this value. You can do this by setting the API referenceThe Parser objectAfter a new Properties:
