Create nested list from Multidimensional Array

Question

I have an array in PHP, which looks like this:

array (
    [0] => array (
        [id] => 1
        [title] => \"Title 1\"
        [parent_id] =>         


        

Answer 1

The following array:

Array
(
    [0] => Content
    [1] => Array
        (
            [0] => International
            [1] => Array
                (
                    [0] => Mexico
                    [1] => Array
                        (
                            [0] => Tamaulipas
                        )

                    [2] => USA
                )

        )

)

With this function:

function r($element) {
    foreach ($element as $value) {
        if (!is_array($value)) {
            echo "
";
            echo $value;
        } else {
            echo "
";
            r($value);
            echo "";
            echo "
";
        }
    }
}

PHP code:

echo "
";
r($array);
echo "
";

Returns:

    
Public
    
User
    
Content
        

            
International
                

                    
Mexico
                        

                            
Tamaulipas
                        
  
                    
                    
USA
