PHP에서 루프를 사용하여 동적 변수 이름을 만드는 방법은 무엇입니까?

<code class="php">for ( $counter = 1; $counter <= $aantalZitjesBestellen; $counter ++) {
  $key = 'seat' . $counter;  // Creates the variable name dynamically
  $$key = $_POST[$key];  // Assigns the POST value to the newly created variable
}

<code class="php">$seat1 = $_POST['seat1'];
$seat2 = $_POST['seat2'];
// ... and so on

<code class="php">$seats = [];
for ( $counter = 1; $counter <= $aantalZitjesBestellen; $counter ++) {
  $key = 'seat' . $counter;
  $seats[$key] = $_POST[$key];
}

<code class="php">$seats = [
  'seat1' => $_POST['seat1'],
  'seat2' => $_POST['seat2'],
  // ... and so on
];</code>
