Download the PHP package nadar/parser without Composer
On this page you can find all versions of the php package nadar/parser. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.
Informations about the package parser
This fork is required because the project seems to be abandoned, but there are some php 8.2 fixes required. See => https://github.com/WhichBrowser/Parser-PHP/pull/673 We have kept the same namespace, so you just have to replace whichbrowser/parser with nadar/parser in your composer.json
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.
About WhichBrowser
But 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?
Because everybody lies. Seriously, there is not a single browser that is completely truthful. Almost all browsers say they are Netscape 5 and almost all WebKit browsers say they are based on Gecko. Even Internet Explorer 11 now no longer claims to be IE at all, but instead an unnamed browser that is like Gecko. And it gets worse. That is why it is 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:
JUC (Linux; U; 2.3.6; zh-cn; GT-I8150; 480*800) UCWEB8.7.4.225/145/800
UC Browser 8.7 on a Samsung Galaxy W running Android 2.3.6
Android is never mentioned
Mozilla/5.0 (Series40; Nokia501/10.0.2; Profile/MIDP-2.1 Configuration/CLDC-1.1) Gecko/20100401 S40OviBrowser/3.0.0.0.73
Nokia Xpress 3.0.0 on a Nokia Asha 501 running Nokia Asha Platform
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.
Opera/9.80 (X11; Linux zvav; U; zh) Presto/2.8.119 Version/11.10
Opera Mini on a Nokia 5230 running Series60 5.0
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.
Requirements
WhichBrowser 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 it
You can install WhichBrowser by using Composer - the standard package manager for PHP. The package is called whichbrowser/parser
.
composer require nadar/parser
You can easily update WhichBrowser by running a simple command.
composer update nadar/parser
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 it
The first step require the Composer autoloader:
The second step is to create a new WhichBrowser\Parser
object. This object will contain all the information the library could find about the browser. The object has a required parameter, either the headers send by the browser, or a useragent string. Using the headers is preferable, because it will allow a better detection, but if you have just the useragent string, this will also work.
For example:
or:
The variable $result
now contains an object which you can query for information. There are various ways to access the information.
First of all, you can call to toString()
function to get a human readable identification:
Another possiblity is to query the object:
You can also access these properties directly:
Or access parts of these properties directly:
Finally you can also query versions directly:
Options
It is possible to set additional options by passing an array as the second parameter when creating the Parser
object.
Disabling detection of bots
In 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.
Enable result caching
WhichBrowser 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 Parser
object, or use the setCache()
function to set it afterwards. WhichBrowser has been tested to work with the adapters provided by PHP Cache. For a list of other packages that provide adapters see Packagist.
For example, if you want to enable a memcached based cache you need to install an extra composer package:
composer require cache/memcached-adapter
And change the call to WhichBrowser/Parser as follows:
or
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 cacheExpires
option or passing it as a second parameter to the setCache()
function.
API reference
The Parser object
After a new WhichBrowser\Parser
object is created, it contains a number of properties and functions. All of these properties are guaranteed to be present.
Properties:
browser
an object that contains information about the browser itselfengine
an object that contains information about the rendering engineos
an object that contains information about the operating systemdevice
an object that contains information about the device
Functions:
getType()
Returns the type
and subtype
property of the device
object. If a subtype is present it is concatenated to the type and seperated by a semicolor, for example: mobile:smart
or gaming:portable
. If the subtype is not applicable, it just return the type, for example: desktop
or ereader
.
isType($type [,$type [,$type [,$type]]])
If a single argument is used, the function returns true
if the argument matches the type
propery of device
object. The argument can optionally also provide a subtype by concatenating it to the type and seperating it with a semicolon. It can use multiple arguments in which case the function returns true
if one of the arguments matches. If none of the arguments matches, it returns false
isMobile()
Return true
if the browser is a mobile device, like a phone, tablet, ereader, camera, portable media player, watch or portable gaming console. Otherwise it returns false
.
isBrowser($name [, $comparison, $version])
Is used to query the name
and version
property of the browser
object. The funcion can contain a single argument to a simple comparison based on name
, or three arguments to compare both name
and version
. The first argument always contains the name of the browser. The second arguments is a string that can container either <
, <=
, =
, =>
or >
. The third is an integer, float or string that contains the version. You can use versions like 10
, 10.7
or '10.7.4'
. For more information about how version comparisons are performed, please see the is()
function of the Version
object.
isEngine($name [, $comparison, $version])
Is used to query the name
and version
property of the engine
object. This function works in exactly the same way as isBrowser
.
isOs($name [, $comparison, $version])
Is used to query the name
and version
property of the os
object. This function works in exactly the same way as isBrowser
.
