Multidimensional array to HTML unordered list

Question

I have the following array which I want to transform into an unordered list (HTML).

Array
(
    [0] => Array
        (
            [url] => /
            [         


        

Answer 1

Try a function like this:

function ToUl($input){
   echo "
";

   $oldvalue = null;
   foreach($input as $value){
     if($oldvalue != null && !is_array($value))
        echo "";
     if(is_array($value)){
        ToUl($value);
     }else
        echo "
" + $value;
      $oldvalue = $value;
    }

    if($oldvalue != null)
      echo "
";

   echo "
";
}

[Edit]

I'll leave the function which creates a li for every array, which is simpler, in case any reader needs it:

function ToUl($input){
   echo "
";

   foreach($input as $value)
     if(is_array($value)){
        echo "
";
        ToUl($value);
        echo "
";
     }else
        echo "
" + $value + "
";

   echo "
";
}
