Conditional text based on login

I figured this one out, just did a quick if else PHP.

I could use this – care to share the PHP with me? I am great at following directions & cut/paste, but do not understand PHP at all.

Give me a “find SKLDJHF and change to LKFOITR” and I’m good!

<?php

global $user_login, $user_identity;
get_currentuserinfo();
if ($user_login) :
?>
<h2>Welcome Back <?php echo $user_identity; ?>!</h2>

   <ul> <?php
$date = date("D M j G:i:s Y", time()+60*60*$diff=-3);
print ($date);
?>
   <br /><?php wp_register(); ?><br />
   <a href="<?php echo get_settings('siteurl') . '/wp-login.php?action=logout&amp;redirect_to=' . $_SERVER['REQUEST_URI']; ?>"><?php _e('Logout'); ?></a>
    </ul>

    DO LOGGED IN STUFF HERE

<?php else : ?>
<li><h2>Welcome Guest! </h2>

Please Login or <?php wp_register('', ''); ?> for member's benefits.<br />
    <form name="loginform" id="loginform" action="<?php echo get_settings('siteurl'); ?>/wp-login.php" method="post">
    <label><?php _e('Login') ?>:&nbsp;&nbsp;<input type="text" name="log" id="log" value="" size="10" maxlength="30" tabindex="7" /></label><br /><br />
    <label><?php _e('Password') ?>:&nbsp;&nbsp;<input type="password" name="pwd" id="pwd" value="" size="10" maxlength="30" tabindex="8" /></label><br /><br />
    <input type="hidden" name="rememberme" value="forever" />
    <center><input type="submit" name="submit" value="<?php _e('Login'); ?> &raquo;" tabindex="9" /></center>
    <input type="hidden" name="redirect_to" value="<?php echo $_SERVER['REQUEST_URI']; ?>"/>
    </form>
<?php endif; ?>

Wow – that was fast!

Now I need to know how to use it. I think I cut/paste it into a PHP file. Which one?

Do I need to put some code somewhere else to activate this?
