PHP Checkbox values to ARRAY and to UL LI list

I've been trying lately to store selected checkbox values to an Array and show them in UL and LI lists.

Here is how???

     Hummer

     Party Limo

	if(isset($_POST["csubmit"])){
		print_r($_POST['fleet']);	
		
		$arr = $_POST['fleet'];
		
		echo '
';
		foreach($arr as $key => $value):
			echo '
' . ucwords($value) . '
';
		endforeach;
		echo '
';		
	}
