                    )

            )
    )

I have this array. I need per 'deelnemer' the individual values. I tried:

echo '<select>';
foreach ($xml as $obj)
{
    foreach ($obj['deelnemer'] as $ob)
    {

            echo '<option value='.$ob['naam'].'>'.$ob['naam'].'</option>';

    }
}
echo '</select>';

But i keep getting error messages. The only thing i can substract atm is 'deelnemer'.

I need a PHP code to create a loop (for each) with a dropdown select with the names of the participants.

Answer 1

$xml is not an array but an object, so in order to access its elements use -> instead of [] as explained in php how to access object array

Try this code:

echo '<select>';
foreach ($xml->deelnemer as $ob) {
  echo '<option value="' . $ob->naam . '">' . $ob->naam . '</option>';
}
echo '</select>';
