1. How can I get detailed browser capabilities from user agent string from my own PHP code?

Here’s typical example:

global $quick_browscap;
if(isset($quick_browscap) && is_object($quick_browscap)){
    $agent = 'Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_2; en-us) AppleWebKit/525.18 (KHTML, like Gecko) Version/3.1.1 Safari/525.18';

    * First argument is user agent (string, optional, default is $_SERVER['HTTP_USER_AGENT']).
    * Second argument is return array or not (bool, optional, default is false to return object).
    * Example to return capabilities for given agent string $agent as PHP array.
    $bw_info = $quick_browscap->get_browser($agent, true);

    /* Output $bw_info array */
    echo '<pre>'.print_r($bw_info, true).echo '</pre>';

This is output of the preceeding code:

    [browser_name] => Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_2; en-us) AppleWebKit/525.18 (KHTML, like Gecko) Version/3.1.1 Safari/525.18
