Weird PHP issue with Server 4.0.3

Question

Yosemite 10.10.2
OS X Server 4.0.3
default PHP installation 5.5.14
Ok, so I successfully added a couple of Virtual Host websites, strictly using the OS X Server.app, and I can browse on my local network using the private url I gave them.
The problem is, on one of my websites, the PHP that renders the menu isn't working properly. I'm not smart enough to understand exactly why or what's going wrong. It does this whether I host the files in the standard document root, or my own virtual host folder.
Here's how it looks when hosted by OS X Server's Apache (i.e. - wrong)
And for comparison, here's how it looks using MAMP (i.e. - perfect)
The index.php of the site is literally just this and nothing more…
<?php
     include('head.html');
?>
<?php
     include('logo.html');
?>
<?php
     include('menu.html');
?>
<?php
     include('showreel/showreel.html');
?>
The PHP error appears to be happening in the menu.html portion, in particular the array section. I've copied it here for you to see http://pastebin.com/fpAi2YjF
I have a info.php file that confirms php is on, and the checkbox 'Enable PHP Web Applications' is checked in Server.app.
Now, I now I could use MAMP, but I'd rather not. I just want a simple, clean OS X solution. I've paid for Server.app and I want to use it. I'm only hosting these sites for dev purposes on my local network. Also I have no use for MySQL, etc. MAMP is overkill for my needs.
Any idea what I did wrong? Or what I need to change? I'm thinking maybe apple's version of PHP may have slightly different settings.

Mark,
Using the following code I got a properly formatted bullet list - as you would expect as I do not have the css.
<?php
  ini_set('display_errors', '1');
  $current_url = $_SERVER['REQUEST_URI'];
?>
<?php
$menu_items = array(
        "Showreel" => "/",
        "Motion" => "/motion/index.php",
        "Animation" => "/animation/index.php",
        "Interface" => "/interface/index.php",
        "Live Action" => "/live_action/index.php",
        "Info" => "/info/index.php",
?>
<div class="main_menu_container">
        <ul id="main_menu">
        <?php
    foreach ($menu_items as $title => $url)
        if($current_url==$url)
        ?>              
                        <li class='active'><?php echo $title; ?></a></li>
                        <?php
                    else  
                        ?>
                        <li><a href="<?=$url?>"><?php echo $title; ?></a></li>
                        <?php
        ?>
        </ul>
</div>
