Hacking around with PHP to have a better solution than get_browser()
Please see changelog for a list of recent changes.
The browscap.ini file is a database which provides a lot of details about browsers and their capabilities, such as name, versions, Javascript support and so on.
The browscap.ini, which provides a lot of details about browsers and their capabilities, such as name, versions, Javascript support and so on.
PHP's native get_browser() function parses this
file and provides you with a complete set of information about every browser's
details, But it requires the path to the browscap.ini file to be specified in
the php.ini browscap
directive which is flagged as PHP_INI_SYSTEM.
Since in most shared hosting environments you have not access to the php.ini file, the browscap directive cannot be modified and you are stuck with either and outdated database or without browscap support at all.
Browscap is a standalone class for PHP >=5.3 that gets around the limitations of
get_browser() and manages the whole thing.
It offers methods to update, cache, adapt and get details about every supplied
user agent on a standalone basis.
It's also much faster than get_browser() while still returning the same results.
If you can switch away from get_browser() then you definitely should. This implementation is very inferior
when compared to browscap-php. Not only the pure PHP implementation is way faster, especially with opcache,
as you can see here: https://github.com/browscap/browscap-php#features but also it is actually being updated,
in contrary to get_browser().
So if there are some RAM, speed issues, or problems with ini parsing, they will most likely be fixed in browscap-php
and WON'T in get_browser().
Browscap is a Composer package.
The Browscap.ini database now has an official site at http://browscap.org/.
A quick start guide is available on the GitHub wiki at the original repostitory for this project, at the following address: https://github.com/GaretJax/phpbrowscap/wiki/QuickStart (the Wiki is on the original project page)
Here is a non-exhaustive feature list of the Browscap class:
- Very fast
- at least 3 times faster than get_browser() when not using opcache
- 20 or more times faster than get_browser() when using opcache (see tests)
- Standalone and fully PHP configuration independent (no need for php.ini setting)
- Fully get_browser() compatible (with some get_browser() bugs fixed)
- User agent auto-detection
- Returns object or array
- Parsed .ini file cached directly into PHP arrays (leverages opcache)
- Accepts any .ini file (even ASP and lite versions)
- Auto updated browscap.ini file and cache from remote server with version checking
- Fully configurable, including configurable remote update server and update schedules
