mixed get_browser(string $user_agent[, bool $return_array = false])
Attempts to determine the capabilities of the user's browser, by looking up the browser's information in the browscap.ini file.
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;
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.
- string $user_agent: The 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.

$browser = get_browser(null, true);
The above example will output something similar to:

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.
