README

This is a userland replacement for PHP's native get_browser() function, which is officially supported by the Browser Capabilities Project.

Note that you are currently viewing the 4.x series. If you're looking for the unsupported 2.x version, please read the documentation for that branch here.

Installation

Run the command below to install via Composer

composer require browscap/browscap-php 

Then you may identify the current user agent this way:

$cache = new \Roave\DoctrineSimpleCache\SimpleCacheAdapter($doctrineFileCache); // or maybe any other PSR-16 compatible caches
$logger = new \Monolog\Logger('name'); // or maybe any other PSR-3 compatible logger

$browscap = new \BrowscapPHP\Browscap($cache, $logger);
$info = $browscap->getBrowser();

Recommended Setup

Before you can start, you have to download the browscap.ini file and convert it into a cache. There are two ways.

a. Download the file and convert it in two steps. The downloaded file will be stored in a local file, but there is no check if the remote file has changed. If your cache gets corrupted you only need to rerun the convert command.

vendor/bin/browscap-php browscap:fetch
vendor/bin/browscap-php browscap:convert

b. Download the file and convert it in one step. The downloaded file will not be stored in a local file, but there is a check if the remote file has changed. If your cache gets corrupted you have clean the cache and restart the process.

vendor/bin/browscap-php browscap:update

If you want to autoupdate the used cache, we recommend a separate cron job that calls the command listed above.

What's changed in version 4.x

BC breaks listed

• Strict type hints have been added throughout. This may break some type assumptions made in earlier versions.
• CheckUpdateCommand, ConvertCommand, LogfileCommand, ParserCommand, UpdateCommand removed setCache methods so that caches must now be constructor-injected
• Many classes are now final - use composition instead of inheritance
• PropertyFormatter now assumes any non-truthy values are false
• checkUpdate method now throws an exception if we could not determine the "remote" version, or if there is no version in cache already.
• log method was removed

Changes

• for caching the Doctrine Cache package is used
  • Any other Cache compatible with PSR-16 could be used
• instead of the debug flag for the CLI commands the verbose flag has to be used

What's changed in version 3.x

Changes

• the namespace was changed to BrowscapPHP
• the Browscap class was split into pieces
  • for caching the WurflCache package is used
  • for downloading the browscap.ini the Guzzle HTTP package is used

Removed features

• the autoupdate function was removed
• all public properties were removed

New features

• now it is possible to use other caches than the file cache (see the WurflCache package formore information)
• now it is possible to write your own formatter to change the output format
• now it is possbile to set a PSR-3 compatible logger

Setup Examples

Update your setup to version 4.x

This is the base setup in version 3.x.

$bc = new \BrowscapPHP\Browscap();

$adapter = new \WurflCache\Adapter\File([\WurflCache\Adapter\File::DIR => $cacheDir]);
$bc->setCache($adapter);

$logger = new \Monolog\Logger('name');
$bc->setLogger($logger);

$result = $bc->getBrowser();

Change this to the base setup for version 4.x. to use the current cache directory

$fileCache = new \Doctrine\Common\Cache\FilesystemCache($cacheDir);
$cache = new \Roave\DoctrineSimpleCache\SimpleCacheAdapter($fileCache);

$logger = new \Monolog\Logger('name');

$bc = new \BrowscapPHP\Browscap($cache, $logger);
$result = $bc->getBrowser();

NOTE: You may use any other cache which implements the PSR-16 interface.

Using the full browscap.ini file

$bc = new \BrowscapPHP\BrowscapUpdater();
$bc->update(\BrowscapPHP\Helper\IniLoaderInterface::PHP_INI_FULL);

Setting up a proxy configuration

If you are behind a proxy or need a spcific configuration, you have to set up a client instance. See into the Guzzle documentation for more information about this.

$proxyConfig = [
    'proxy' => [
        'http'  => 'tcp://localhost:8125',
        'https' => 'tcp://localhost:8124',
    ],
];
$client = new \GuzzleHttp\Client($proxyConfig);
$bcu = new BrowscapUpdater();
$bcu->setClient($client);

Usage Examples

Taking the user agent from the global $_SERVER variable

$bc = new \BrowscapPHP\Browscap();
$current_browser = $bc->getBrowser();

Using a sample useragent

$bc = new \BrowscapPHP\Browscap($cache, $logger);
$current_browser = $bc->getBrowser($the_user_agent);

the CLI commands

NOTE: If you don't want to use a file cache, you could not use the CLI commands. It is not possible to use other caches there at the moment. NOTE: Each operation (fetch, update, check-update) which fetches data from the remote host browscap.org may run into the rate limit of that site. If this happens an Exception is thrown.

Each CLI command returns zero if everything went fine.

check-update

If you only want to check if a new version of the browscap.ini is available, you can use the check-update command.

vendor/bin/browscap-php browscap:check-update

options

• cache (optional) the relative path to your cache directory

return codes

• 1: no cached version found
• 2: no new version availble
• 3: an error occured while checking the cached version
• 4: an error occured while fetching the remote version
• 5: an other error occured

fetch

The fetch command downloads an ini file from browscap.org.

vendor/bin/browscap-php browscap:fetch

options

• cache (optional) the relative path to your cache directory
• remote-file (optional) only required if you dont want to download the standerd file, possible values are
  • PHP_BrowscapINI downloads the standard file (default)
  • Lite_PHP_BrowscapINI downloads the lite file
  • Full_PHP_BrowscapINI downloads the full file
• file (optional) the relative path to the local file where the remote content is stored

return codes

• 3: an error occured while checking the cached version
• 9: an error occured while fetching the remote data
• 10: an other error occured

convert

The convert command reads a local stored browscap.ini file and writes the contents into a cache.

vendor/bin/browscap-php browscap:convert

options

• file (optional) the relative path to the local file where the remote content is stored, this should be the same file as in the fetch command
• cache (optional) the relative path to your cache directory

return codes

• 6: the name of the file to convert is missing
• 7: the file to convert is not available or not readable
• 8: an other error occured while reading the file

update

The update command downloads an ini file from browscap.org and writes the contents into a cache. No local files are created.

vendor/bin/browscap-php browscap:update

options

• remote-file(optional) only required if you dont want to download the standerd file, possible values are
  • PHP_BrowscapINI downloads the standard file (default)
  • Lite_PHP_BrowscapINI downloads the lite file
  • Full_PHP_BrowscapINI downloads the full file
• cache (optional) the relative path to your cache directory

return codes

• 3: an error occured while checking the cached version
• 9: an error occured while fetching the remote data
• 10: an other error occured

parse

The parse command parses a given user agent and writes the result to the console.

vendor/bin/browscap-php browscap:parse

options

• user-agent (required) the user agent which should be parsed
• cache (optional) the relative path to your cache directory

return codes

• 11: an other error occured while parsing the useragent

CLI Examples

Updating the cache using the full browscap.ini file

Note: Both ways to create/update the cache will use the standard mode file as default. If you want more detailed information you may change this with the remote-file option. Please use the help function this parameter.

vendor/bin/browscap-php browscap:update --remote-file Full_PHP_BrowscapINI

Updating a custom cache dir

Each operation expect fetch uses a cache inside the resources directory inside the project. If you update this library with composer, the cache is cleared also. If you want to avoid this and want to set your own cache folder, you can use the cache option. If you do this, you have to set a Cache Instance for this this path.

vendor/bin/browscap-php browscap:update --cache ./browscap-cache
