If you have a UL that does not contain any href elements (e.g. just plain text nexted ul).. I've adjusted Salman's simplehtmldom code to work with that:

$DOM = str_get_html( $catshtml );
$ARR = array( );
function WalkUL( $ul, &$ar )
{
    foreach( $ul->children as $li )
    {
        if ( $li->tag != "li" )
        {
            continue;
        }
        $arar = array( );
        foreach( $li->children as $ulul )
        {
            if ( $ulul->tag != "ul" )
            {
                continue;
            }
            WalkUL( $ulul, $arar );
        }
        $ar[ trim(preg_replace("#]*>(.+]*>|)#is","",$li->innertext)) ] = $arar;
    }
}
WalkUL( $DOM->find( "ul", 0 ), $ARR );
echo "
"; print_r( $ARR );
