PHP Best Practices

Hello, I have a basic design question, in terms of what is "better"
programming.

I have a web site, and am using php pages as includes. some of the php
pages have php tags, and "echo" or "print" the php variables and html.

Like this:
<div id="body">
<?php include("phpincludes/server-nav.php"); ?>
</div>

the php page has code like this:
<div id="header">
<ul>
<li class="tab" <?php if ($thisPage=="Home")
echo " id=\"currentpage\""; ?>>
<a href="http://abf966/LBA/index.php";>Home</a>
</li>
<li class="tab" <?php if ($thisPage=="Introduction")
echo " id=\"currentpage\""; ?>>
<a href="http://abf966/LBA/intro.php";>Introduction</a></li> ...
etc

is it better (or not) to not only echo divs, etc but to create
everything within php tags like this?

<?php echo ('<h2 class="decco" id="hdrTopic">Who We Are Not</h2>'); ?>

OR is this really the same thing, but looks different???

thanks again,
