Question

Example:

class MyRecursiveIteratorIterator extends RecursiveIteratorIterator{

  public function current(){
    echo 'START';
    return parent::current();
  }

}

$it = new MyRecursiveIteratorIterator(new RecursiveArrayIterator($arr));

foreach ($it as $key => $val){

  // here it starts

  echo $val;


  // here it ends
}

So what method should I implement in my class so I can insert my stuff after each element?

Answer 1

If I understand the question correctly, here is code to echo the elements of a php array into a UL html list. If this is not what you’re looking for please add additional information.

echo "<ul>";
foreach($it as $val)
{
    echo "<li>" . $val . "</li>";
}
echo "</ul>";
