For some time now I've been using the following code to dynamically write in html page titles and add an active class to menu items. Is this still a good why to achieve this or are there better/smarter/optimal ways of achieving the same thing?

<?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='contact.php'? 'class="active"' : '');?>

Menu example

<ul id="nav">
<li><a href="index.php"  target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='index.php'? 'class="active"' : '');?>><span>Home</span></a></li>
<li><a href="services.php"  target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='services.php'? 'class="active"' : '');?><?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='services-landlords.php'? 'class="active"' : '');?><?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='services-sellers.php'? 'class="active"' : '');?><?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='services-tennants.php'? 'class="active"' : '');?>><span>Our Services</span></a></li>
<li><a href="for-sale.php" target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='sales.php'? 'class="active"' : '');?>><span>Sales</span></a></li>
<li><a href="to-let.php" target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='lettings.php'? 'class="active"' : '');?>><span>Lettings</span></a></li>
<li><a href="register.php"  target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='register.php'? 'class="active"' : '');?><?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='register-thanks.php'? 'class="active"' : '');?>><span>Register</span></a></li>
<li><a href="contact.php"  target="_parent" <?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='contact.php'? 'class="active"' : '');?>><span>Contact Us</span></a></li>
</ul>

Page title Example

<?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='services.php'? 'Services' : '');?>
<?php echo (basename($_SERVER['SCRIPT_FILENAME'])=='services-landlords.php'? 'Services for Landlords' : '');?>
