Question

我对某事很不安全。如果我想删除我的数据库的整个表，代码是否正确？或者我是否需要添加更多代码？它需要一个while循环，还是有什么我误解的？

del.php：

<form method="POST" action="del.php">
  <button type="button" name="delete" id="delete" value="Delete">
</form>

<?php
    include 'connect.php';

    $stmt = $mysqli->prepare("DELETE * FROM numbers") or die($mysqli->error);
?>

Answer 1

您可以删除通配符*，即

$stmt = $mysqli->prepare("DELETE FROM numbers") or die($mysqli->error);

Answer 2

必须是DELETE FROM numbers

$stmt = $mysqli->prepare("DELETE FROM numbers") or die($mysqli->error);

如果你想截断，你可以

TRUNCATE [TABLE] numbers

删除语句mysqli
