使用PHP和SQL在复选框上提交多个值

<form method="post" action="process.php">
  <input type="checkbox" name="fruits[]" value="apple"> Apple<br>
  <input type="checkbox" name="fruits[]" value="banana"> Banana<br>
  <input type="checkbox" name="fruits[]" value="orange"> Orange<br>
  <input type="submit" value="Submit">
</form>

$selectedFruits = $_POST['fruits'];

// 假设已经建立了与数据库的连接
foreach ($selectedFruits as $fruit) {
  $sql = "INSERT INTO fruits (name) VALUES ('$fruit')";
  // 执行SQL语句
  // ...
}
