print $HTTP_USER_AGENT; // the variable is already in the global scope.
also $ua = getenv('HTTP_USER_AGENT');
Most variables are automatically made a part of the environment in a PHP
script. It's one of the ways PHP makes scripting easier.
The online manual is invaluable for this type of info. http://www.php.net/
Also, write a short script and run it as so:
<? phpinfo(); ?>
You'll see a myriad of variables and their values. It's also handy for
debugging. You can include phpinfo() anywhere to see the output values of
your script.
