[RESOLVED] Foreach within a Foreach

[Royalmike]

I'm trying to create a php nav bar by pulling the links and the corresponding images from a preset array. I have that working with a foreach loop. The problem is some(Not All) links in the nav bar have sub links. Those sub links are stored within another array named the same as main link.

If one of the main links has sub links then I want another foreach loop(inside the one listing the main links) to list the sub links.

Sorry if this explanation is really vague. I just want to be able to execute a foreach loop inside another foreach loop.

<?php
$titles=array("test", "test2");//Main Titles

$test2=array("hello", "hello2");//One of the links that have sublinks. The array is filled with the sublinks
?>

<ul class="nav">
	<?php 
		foreach($titles as $temp)
		{
	 ?>
				<li>
					<a href="<?php echo $temp ?>.php">

					<?php
					  if($pagetitle != $temp) //Pagetitle is declared on all the main pages. This is just an include page.
						{
					?>
						<img src="<?php echo $temp ?>.png"  />
						<img src="<?php echo $temp ?>roll.png"  class="hover" /><!--CSS Rollover-->
				<?php 
						} 

					else{
				?>
						<img src="<?php echo $temp ?>roll.png"  /><!--Current Page-->
					</a>

						<?php
						//PROBLEM
							if($temp == "test2" /*|| Others || */)
							{
								echo $temp;
								foreach($temp as $temp2)
								{
									echo $temp2;
								}
							}
							?>
					<?php } ?>
			</li>
		<?php } ?>
</ul>

Ignore the last echo of temp(NOT TEMP2) in the second foreach loop. I was testing something.

Yes you can. You can even "nest" the arrays, that is make an array of arrays...

$titles = array(
			'main1' => array('sub11', 'sub12', 'sub13'),
			'main2' => array('sub21', 'sub22', 'sub23')
				);

foreach ($titles as $mainitem=>$sub) {
	echo $mainitem . '<br />';
	foreach ($sub as $subitem) {
		echo $subitem . '<br />';
	}
	echo '<br />';
}

btw this works too and you dont have to drop in and out of php mode quite so often:

<?php
echo '<a href="' . $temp '.php">';
?>

Thank you, it works perfectly now. Arrays inside arrays always confuse me, but I guess they come in handy if you know how to use them.
