* The BrowserDetection class facilitates the identification of the user's environment such as Web browser, version,
* platform or if it's a mobile device.
* $browser = new BrowserDetection();
* if ($browser->getBrowser() == BrowserDetection::BROWSER_FIREFOX && $browser->getVersion() >= 5) {
* echo 'You have FireFox version 5 or greater.';
* The class is an updated version of Chris Schuld's Browser class version 1.9 which is unmaintaned since August 20th,
* 2010. Chris' class was based on the original work from Gary White.
* + Version 2.1. Added IE 11+ support.
* + Version 2.0 is (almost) a complete rewrite based on Chris Schuld's Browser class version 1.9 plus changes below
* + Added support for Opera Mobile
* + Added support for the Windows Phone (formerly Windows Mobile) platform
* + Added support for BlackBerry Tablet OS and BlackBerry 10
* + Added support for the Symbian platform
* + Added support for Bingbot
* + Added support for the Yahoo! Multimedia crawler
* + Removed iPhone/iPad/iPod browsers since there are not browsers but platforms - test them with getPlatform()
* + Removed support for Shiretoko (Firefox 3.5 alpha/beta) and MSN Browser
* + Merged Nokia and Nokia S60
* + Updated some deprecated browser names
* + Many public methods are now protected
* + Documentation updated
* + Added detection of IE compatibility view - test with getIECompatibilityView()
* + Added support for all (deprecated) Netscape versions
* + Added support for Safari < 3.0
* + Better Firefox version parsing
* + Better Opera version parsing
* + Better Mozilla detection

//--- MAGIC METHODS ------------------------------------------------------------------------------------------------
* BrowserDetection class constructor.

* Determine how the class will react when it is treated like a string.
* @return string Returns an HTML formatted string with a summary of the browser informations.

* Compare two version number strings.
* @param string $sourceVer The source version number.
* @param string $compareVer The version number to compare with the source version number.

* Get the version of AOL (if any). AOL releases "optimized" Internet Explorer and Firefox versions. In the making
* they add their version number in the user agent string of these browsers.
* @return string Returns the version of AOL or an empty string if no AOL version was found.
* Get the name of the browser. All of the return values are class constants. You can compare them like this:
* $myBrowserInstance->getBrowser() == BrowserDetection::BROWSER_FIREFOX.
* @return string Returns the name of the browser.
* Get the name and version of the browser emulated in the compatibility view mode (if any). Since Internet
* Explorer 8, IE can be put in compatibility mode to make websites that were created for older browsers, especially
* IE 6 and 7, look better in IE 8+ which renders web pages closer to the standards and thus differently from those
* @param bool $asArray Determines if the return value must be an array (true) or a string (false).
* @return mixed If a string was requested, the function returns the name and version of the browser emulated in the
* compatibility view mode or an empty string if the browser is not in compatibility view mode. If an array was
* requested, an array with the keys 'browser' and 'version' is returned.
* Get the name of the platform on which the browser is runned on (such as Windows, Apple, iPhone, etc.). All of the
* return values are class constants. You can compare them like this:
* $myBrowserInstance->getPlatform() == BrowserDetection::PLATFORM_ANDROID.
* @return string Returns the name of the platform or BrowserDetection::PLATFORM_UNKNOWN if unknown.
* Get the user agent value used by the class to determine the browser details.
* @return string The user agent string.
* Get the version of the browser.
* @return string Returns the version of the browser or BrowserDetection::VERSION_UNKNOWN if unknown.
* Determine if the browser is from AOL. AOL releases "optimized" Internet Explorer and Firefox versions. In the
* making they add their details in the user agent string of these browsers.
* @return boolean Returns true if the browser is from AOL, false otherwise.
* Determine if the browser runs Google Chrome Frame (it's a plug-in designed for Internet Explorer 6+ based on the
* open-source Chromium project - it's like a Chrome browser within IE).
* @return boolean Returns true if the browser is using Google Chrome Frame, false otherwise.
* Determine if the browser is in compatibility view or not. Since Internet Explorer 8, IE can be put in
* compatibility mode to make websites that were created for older browsers, especially IE 6 and 7, look better in
* IE 8+ which renders web pages closer to the standards and thus differently from those older versions of IE.
* @return boolean Returns true if the browser is in compatibility view, false otherwise.
* Determine if the browser is from a mobile device or not.
* @return boolean Returns true if the browser is from a mobile device, false otherwise.
* Determine if the browser is a robot (Googlebot, Bingbot, Yahoo! Slurp...) or not.
* @return boolean Returns true if the browser is a robot, false otherwise.
* Set the user agent to use with the class.
* @param string $agentString The value of the user agent. If an empty string is sent (default),
* $_SERVER['HTTP_USER_AGENT'] will be used.
$agentString = $_SERVER['HTTP_USER_AGENT'];
