You may add items to the various -user agent arrays if needed. - -Example -======= - -When the User Agent class is initialized it will attempt to determine -whether the user agent browsing your site is a web browser, a mobile -device, or a robot.

It is not a complete list of bots. - There are hundreds of them so searching for each one would not be very efficient. If you find that some bots - that commonly visit your site are missing from the list you can add them to your - **application/config/user_agents.php** file. - - .. php:method:: is_referral() - - :returns: TRUE if the user agent is a referral, FALSE if not - :rtype: bool - - Returns TRUE/FALSE (boolean) if the user agent was referred from another site. - - .. php:method:: browser() - - :returns: Detected browser or an empty string - :rtype: string - - Returns a string containing the name of the web browser viewing your site. - - .. php:method:: version() - - :returns: Detected browser version or an empty string - :rtype: string - - Returns a string containing the version number of the web browser viewing your site. - - .. php:method:: mobile() - - :returns: Detected mobile device brand or an empty string - :rtype: string - - Returns a string containing the name of the mobile device viewing your site. - - .. php:method:: robot() - - :returns: Detected robot name or an empty string - :rtype: string - - Returns a string containing the name of the robot viewing your site. - - .. php:method:: platform() - - :returns: Detected operating system or an empty string - :rtype: string - - Returns a string containing the platform viewing your site (Linux, Windows, OS X, etc.). - - .. php:method:: referrer() - - :returns: Detected referrer or an empty string - :rtype: string - - The referrer, if the user agent was referred from another site.
