Like Erwin noticed, the code wasn't correct. I've updated it re. commas
and semicolons.
function makelist($a)
{
static $level = -1;
++$level;
$spc = str_repeat(' ', 2 * $level);
$html = "$spc<ul>\n";
foreach ( $a as $i )
{
if ( is_array($i) )
$html .= makelist($i);
else
$html .= "$spc <li>$i</li>\n";
}
$html .= "$spc</ul>\n";
--$level;
return $html;
}
echo makelist($notes));
