This code snipped help me to print dynamic arrays try this one:

function makeNestedList(array $Array){
    $Output = '<ul>';
    foreach($Array as $Key => $Value){
        $Output .= "<li><strong>{$Key}: </strong>";
        if(is_array($Value)){
            $Output .= makeNestedList($Value);
        }else{
            $Output .= $Value;
        }
        $Output .= '</li>';
    }
    $Output .= '</ul>';
    return $Output;
}
$Data = array("Some Info" => array("A" => "a", "B" => array("B1" => "b1", "B2" => "b2"), "C" => array("C1" => array("C11" => "c11", "C12" => "c12", "C13" => array("C131" => "c131", "C132" => "c132")), "C2" => "c2")));
echo makeNestedList($Data);
