Thanks Poyzn.
I'v been working on my own loop since and I'm getting a similar result to your's.

PHP Code:

echo "\n\n\n<ul id=\"nav_menu\"><!-- Unordered List Start Tag -->\n";

foreach ($main_menu as $key => $keyValue)
{
        echo "\n<li class=\"main_menu\"><a href='". $keyValue['link'] ."'>". $keyValue['name'] ."</a>";
             { echo "\n\n<ul class=\"sub_menu\">\n";
               foreach ($keyValue as $keyValuex)   {
                       echo "\n<li><a href='". $keyValuex['link'] ."'>". $keyValuex['name'] ."</a></li>\n";

                                                   }
                                                   { echo "</ul><!-- Sub Menu Unordered List Item Closing Tag -->";
             }
             } { echo"\n</li><!-- Sub Menu List Item Closing Tag -->\n";
          //echo "</li>";

}
}
echo "\n</ul><!-- Unordered List End Tag -->\n"; 


<ul id="nav_menu"><!-- Unordered List Start Tag -->

<li class="main_menu"><a href='index.php'>HOME PAGE</a>

<ul class="sub_menu">

<li><a href='i'>i</a></li>
</ul><!-- Sub Menu Unordered List Item Closing Tag -->
</li><!-- Sub Menu List Item Closing Tag -->

<ul class="sub_menu">

<li><a href='i'>i</a></li>
</ul><!-- Sub Menu Unordered List Item Closing Tag -->
</li><!-- Sub Menu List Item Closing Tag -->

</ul><!-- Unordered List End Tag -->

I have 2 issues, first should the Menu's that dont have a Sub menu array not have closing </li> tag's ,for example the first Home link
<li class="main_menu"><a href='index.php'>HOME PAGE</a>
should it be <li class="main_menu"><a href='index.php'>HOME PAGE</a></li>

The second issue is for some reason the Loop is creating 2 unwanted List items at the start of each UL , example

<li><a href='H'>H</a></li>

<li><a href='i'>i</a></li>
