Need help creating CSS current page selection using PHP

[bgbs]

How do I css menu to show current page using php?

Into each unique page I inserted this code 

<?php $page = "about"; ?> 

( "about" is the name of page used in this example )

Now I'm stock with the rest.

 

Someone suggested that I should write the php like this:

<li><a href="about.php" <?php if ($page == 'about') { ?>class="current"<?php } ?>>About</a></li>

Is this correct usage?  Or is there a better way to do this?

 

Please let me know

Either your way, or my way. either is sufficient

 

$referer = basename($_SERVER['SCRIPT_NAME']);
<?php if ($referer == 'about.php') { echo 'class="current"'; } ?>
