Your code is perfect just make sure your URL must have a as index.php?a=somevalue.

<ul>
    <?php
        if(isset($_GET['a']))
        {
            $var=$_GET['a'];
    ?>
        <li>
            <a href = ""<?php echo $var; ?>.php" rel="">
                <span><?php echo $var." "; ?>Home</span>
            </a>
        </li>
        <li><a href = ''><span>HOD</span></a></li>
        <li>
            <a href = "faculty.php?b=<?php echo $var; ?>" rel="">
                <span>Faculty</span>
            </a>
        </li>
    <?php
        }
    ?>
</ul>
