get_browser

GET_BROWSER(3)								 1							    GET_BROWSER(3)

get_browser - Tells what the user's browser is capable of

SYNOPSIS

       mixed get_browser ([string  $user_agent], [bool	$return_array = false])

DESCRIPTION

	Attempts to determine the capabilities of the user's browser, by looking up the browser's information in the browscap.ini file.

PARAMETERS

	      o $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.  You can bypass this parameter with a NULL value.

	      o $return_array
		- If set to TRUE, this function will return an array instead of an object.

RETURN VALUES

	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(3), reload, and check for the value.

EXAMPLES

       Example #1

	      Listing all information about the users browser

	      <?php
	      echo $_SERVER['HTTP_USER_AGENT'] . "

";

	      $browser = get_browser(null, true);
	      print_r($browser);
	      ?>

	      The above example will output something similar to:

	      Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3

	      Array
	      (
		  [browser_name_regex] => ^mozilla/5.0 (windows; .; windows nt 5.1; .*rv:.*) gecko/.* firefox/0.9.*$

NOTES

       Note

	       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.
