get_browserPHP ManualPrevNextget_browserget_browser -- Tells what the user's browser is capable of. Descriptionobject get_browser(string [user_agent] ); get_browser() attempts to determine the capabilities of the user's browser. This is done by looking up the browser's information in the browscap.ini file. By default, the value of $HTTP_USER_AGENT is used; however, you can alter this (i.e., look up another browser's info) by passing the optional user_agent parameter to get_browser(). The information is returned in an object, which will contain various data elements representing, for instance, the browser's major and minor version numbers and ID string; true/false values for features such as frames, JavaScript, and cookies; and so forth. While browscap.ini contains information on many browsers, it relies on user updates to keep the database current. The format of the file is fairly self-explanatory. The following example shows how one might list all available information retrieved about the user's browser. Example 1. Get_browser() example 1  2 <?php 3 function list_array ($array) { 4  while (list ($key, $value) = each ($array)) { 5  $str .= "<b>$key:</b> $value<br>\n"; 6  } 7  return $str; 8 } 9 echo "$HTTP_USER_AGENT<hr>\n"; 10 $browser = get_browser(); 11 echo list_array ((array) $browser); 12 ?> 13  The output of the above script would look something like this: 1  2 Mozilla/4.5 [en] (X11; U; Linux 2.2.9 i586)<hr> 3 <b>browser_name_pattern:</b> Mozilla/4\.5.*<br> 4 <b>parent:</b> Netscape 4.0<br> 5 <b>platform:</b> Unknown<br> 6 <b>majorver:</b> 4<br> 7 <b>minorver:</b> 5<br> 8 <b>browser:</b> Netscape<br> 9 <b>version:</b> 4<br> 10 <b>frames:</b> 1<br> 11 <b>tables:</b> 1<br> 12 <b>cookies:</b> 1<br> 13 <b>backgroundsounds:</b> <br> 14 <b>vbscript:</b> <br> 15 <b>javascript:</b> 1<br> 16 <b>javaapplets:</b> 1<br> 17 <b>activexcontrols:</b> <br> 18 <b>beta:</b> <br> 19 <b>crawler:</b> <br> 20 <b>authenticodeupdate:</b> <br> 21 <b>msn:</b> <br> 22  In order for this to work, your browscap configuration file setting must point to the correct location of the browscap.ini file. For more information (including locations from which you may obtain a browscap.ini file), check the PHP FAQ at http://www.php.net/FAQ.html. Note: Browscap support was added to PHP in version 3.0b2.
