(PHP 4, PHP 5)
get_browser — Tells what the user's browser is capable of
Attempts to determine the capabilities of the user's browser, by looking up the browser's information in the browscap.ini file.
user_agentThe User Agent to be analyzed. By default, the value of HTTP User-Agent header is used; however, you can alter this (i.e., look up another browser's info) by passing this parameter.
You can bypass this parameter with a NULL value.
return_array
If set to TRUE, this function will return an array
instead of an object.
The information is returned in an object or an array which will contain
various data elements representing, for instance, the browser's major and
minor version numbers and ID string; TRUE/FALSE values for features
such as frames, JavaScript, and cookies; and so forth.
The cookies value simply means that the browser itself is capable of accepting cookies and does not mean the user has enabled the browser to accept cookies or not. The only way to test if cookies are accepted is to set one with setcookie(), reload, and check for the value.

Notă:
In order for this to work, your browscap configuration setting in php.ini must point to the correct location of the browscap.ini file on your system.
browscap.ini is not bundled with PHP, but you may find an up-to-date » php_browscap.ini file here.
While browscap.ini contains information on many browsers, it relies on user updates to keep the database current. The format of the file is fairly self-explanatory.
