2D array

[seby]

i am still rather new to 2D arrays, and i am trying to display this array as such:

NAV1
<a href="/nav1/cat1">cat1</a>
<a href="/nav1/cat2">cat2</a>
<a href="/nav1/cat3">cat3</a>

NAV2
<a href="/nav2/cat1">cat1</a>
<a href="/nav2/cat2">cat2</a>
<a href="/nav2/cat3">cat3</a>

$navmenu=array(
       'NAV1' => array(
	                   'cat1' => '/nav1/cat1',
                       'cat2' => '/nav1/cat2',
			           'cat3' => '/nav1/cat3'),
	   'NAV2'  => array(
	                   'cat1' => '/nav2/cat1',
					   'cat2' => '/nav2/cat2',
					   'cat3' => '/nav2/cat3')
					   );

i want to bold NAV1 and NAV2 and have it group the cat1, etc as urls.. i am stuck on this part:

foreach($navmenu as $key => $val)
{ 
    if(isset($navmenu[$key]['NAV1']))
	{ 
		// what now?
    } 
} 

not sure if i am even doing it correctly..

Sounds like what you want to do is something like this:

foreach ($navmenu as $name => $menu) {
	echo '<strong>' . $name . '</strong><br />';

foreach ($menu as $item => $link) {
	echo '<a href="' . $link . '">' . $item . '</a><br />';
}
}

To traverse a 2D array, you need an inner foreach loop to iterate over the inner arrays.

Hope this helps.

alright, one more question.. how do i delete NAV2 and everything below that array using an if statement.

eg. NAV2 is for moderators, i want to hide it if they aren't a mod.. but i cant seem to do it, it will delete the NAV and its associates no matter what.

thanks.

i think i got it.

foreach ($navmenu as $section => $menu)
{
	if(!$moderator)
	{
		unset ($navmenu[$section]);
	}

foreach ($menu as $item => $location)
{
	// code..
} 
}
