What are the potential pitfalls of using the "Ziehen mit Zurücklegen" method in PHP?
The potential pitfalls of using the "Ziehen mit Zurücklegen" method in PHP include the risk of selecting the same item multiple times due to replacement, which may not be desired in certain scenarios. To avoid this issue, you can use a method that removes the selected item from the array after each selection to ensure unique selections.
// Original array of items
$items = ['item1', 'item2', 'item3', 'item4', 'item5'];
// Select a random item and remove it from the array
$randomIndex = array_rand($items);
$selectedItem = $items[$randomIndex];
unset($items[$randomIndex]);
// Output the selected item
echo $selectedItem;
